Substrate-Versatile Approach to Robust Antireflective and Superhydrophobic Coatings with Excellent Self-Cleaning Property in Varied Environments
Robust antireflective and superhydrophobic
coatings are highly
desired in wide applications, such as optical devices, solar cell
panels, architectural and automotive glasses, lab-on chip systems,
and windows for electronic devices. Meanwhile, simple, low-cost, and
substrate-versatile fabrication is also essential toward real applications
of such coatings. Herein, we developed a substrate-versatile strategy
to fabricate robust antireflective and superhydrophobic coatings with
excellent self-cleaning property in varied environments, including
air and oil and after oil contamination. A mixed ethanol suspension,
which consists of 1<i>H</i>,1<i>H</i>,2<i>H</i>,2<i>H</i>-perfluorooctyltriethoxysilane modified
dual-sized silica nanoparticles and acid-catalyzed silica precursor,
was first synthesized. The acid-catalyzed silica precursor could help
to form a highly cross-linked silica network by connecting the silica
nanoparticles, thus significantly enhancing the robustness of coatings.
The as-prepared coatings were able to withstand a water drop impact
test, sand abrasion test, tape adhesion test, and knife and pencil
scratching tests. More importantly, it was also found that the wettability
and self-cleaning property of coatings after oil contamination were
surprisingly different from those in air and oil. These observations
are explainable by the alteration of interface; i.e., the alteration
of interface has significant effects on the functional properties
of coatings. Additionally, the mixed suspension could be sprayed onto
various hard and soft substrates including glass, polyethylene terephthalate
(PET), polycarbonate (PC), and polyĀ(methyl methacrylate) (PMMA), opening
up a feasible route toward varied practical applications in solar
cell panels, optical devices, architectural and automotive glasses,
droplet manipulators, and fluid control
Inkjet Printing Enabled Controllable Paper Superhydrophobization and Its Applications
Papersā
intrinsic interconnected porous structures and hydrophilic
properties usually results in difficulty and complexity in partial
functionalization and regulation processes because the capillary effect
may lead to the fast diffusion of modifiers from one side to the other.
Here, we report a simple and innovative inkjet printing approach that
led to precise hydrophobic functionalization controllable in both
planar and steric dimensions. Fabrication of Janus superwetting papers
and superwettable patterned papers with high precision was achieved
by computer-controlled inkjet printing. Elaborate controls of ink
quantity enabled superhydrophobic functionalization on one side of
the paper substrate, with the opposite side superhydrophilic. Static
water contact angles up to 154Ā° were obtained on the inkjet-printed
side of the paper, thanks to an appropriate combination of surface
chemistry with dual-scale surface roughness. Furthermore, paper-based
microfluidics were fabricated and the resolution of which were estimated
to be ca. 600 Ī¼m. Meanwhile, a paper-based analytical device
for colorimetric sensing of NiĀ(II) was designed and demonstrated based
on superwettable patterned papers by inkjet printing. The inkjet printing
approach reported here represents a key step forward in fabricating
Janus materials and complicate patterns for practical applications
Novel SiO<sub>2</sub>/H<sub>2</sub>Ti<sub>2</sub>O<sub>5</sub>Ā·H<sub>2</sub>OāNanochain Composite with High UVāVisible Photocatalytic Activity for Supertransparent Multifunctional Thin Films
In
the current work, a peroxo titanium complex (PTC) solution was
used as a novel water-soluble precursor to fabricate H<sub>2</sub>Ti<sub>2</sub>O<sub>5</sub>Ā·H<sub>2</sub>O and the SiO<sub>2</sub>/H<sub>2</sub>Ti<sub>2</sub>O<sub>5</sub>Ā·H<sub>2</sub>O-nanochain
composite at low temperature (90ā100 Ā°C). The average
width of H<sub>2</sub>Ti<sub>2</sub>O<sub>5</sub>Ā·H<sub>2</sub>O nanochains is 4.5 Ā± 1.5 nm. Under full-spectrum irradiation,
the Si/Ti-nanochain composite showed good UVāvisible light
absorption and excellent photocatalytic activity, which is 2.8 times
that of P25. In the composite, SiO<sub>2</sub> not only contributes
to the formation of nanochains and improves the catalytic performance
of H<sub>2</sub>Ti<sub>2</sub>O<sub>5</sub>Ā·H<sub>2</sub>O but
also reduces the refractive index of the complex. When coated on transparent
organic substrates, the composite thin film exhibited excellent antireflective
(as high as 99.3% on PC and 98.9% on PMMA) and self-cleaning properties.
Pencil hardness, washing, and tape adhesion tests showed favorable
adhesion-to-substrate and mechanical robustness of thin films, which
make them extremely attractive for applications as highly transparent
and self-cleaning thin films on lenses, photovoltaic cells, and windows
of high-rise buildings
CuO Nanoparticles-Containing Highly Transparent and Superhydrophobic Coatings with Extremely Low Bacterial Adhesion and Excellent Bactericidal Property
Human health and industrial instruments
have been suffering from
bacterial colonization on the surface of materials for a long time.
Recently, antibacterial coatings are regarded as the new strategy
to resist bacterial pathogens. In this work, novel highly transparent
and superhydrophobic coatings with extremely low bacterial adhesion
and bactericidal performance were prepared by spray-coating hydrophobic
silica sol and CuO nanoparticles. The coated glass showed high transmittance
in 300ā2500 nm with a maximum value of 96.6%. Compared with
bare glass, its superhydrophobic characteristics resulted in a reduction
in adhesion of bacteria (Escherichia coli, E. coli) by up to 3.2 log cells/cm<sup>2</sup>. Additionally, the live/dead staining test indicated that
the as-prepared coating exhibited excellent bactericidal performance
against E. coli. Moreover, the as-prepared
coating could maintain their superhydrophobicity after the sand impact
test. The proposed method to fabricate such coatings could be applied
on various substrates. Therefore, this novel hybrid surface with the
abilities to reduce bacterial adhesion and kill attached bacteria
make it a promising candidate for biosensors, microfluidics, bio-optical
devices, household facilities, lab-on-chips, and touchscreen devices
Hydrogel-Encapsulated Enzyme Facilitates Colorimetric Acute Toxicity Assessment of Heavy Metal Ions
Conventional
analysis of heavy metal ions in water requires highly
skilled staff and sophisticated equipment. These limitations make
conventional approaches difficult to perform analysis on-site without
delay. Herein, we report a facile colorimetric sensing system developed
for acute toxicity assessment of heavy metal ions. A bioactive enzyme,
Ī²-galactosidase, was used as sensing agent rather than bacteria
or other higher organisms to improve selectivity and response time.
The developed bioassay is capable of assessing the toxicity of heavy
metal ions such as HgĀ(II), CdĀ(II), PbĀ(II), and CuĀ(II). The effects
of enzyme concentration on the assessing performances (i.e., sensitivity
and response time) of bioassay were explored and illustrated. Generally,
low enzyme concentration facilitates sensitivity enhancement, achieving
a 50% inhibiting concentration (IC<sub>50</sub>) of 0.76 Ī¼M
(=152 ppb) HgĀ(II), and high enzyme concentration ensures quick response,
enabling a response time down to 9 min. Moreover, the enzyme and substrate
were respectively encapsulated by hydrogel to further simplify the
assay procedure and enhance the stability of the enzyme. The hydrogel-encapsulated
enzyme worked well even when heated up to 60 Ā°C and retained
ca. 90% activity after storage for 5 months. Moreover, the developed
toxicity-assessing system is feasible for assessing toxicity of actual
water samples. This assay approach is low cost and time effective
and has no potential ethic issues. In addition, this work paves the
way for the development of toxicity assessment kits for on-site analysis
based on functional bioactive molecules
