In the study, we have utilized several unique amphiphilic block copolymers as
templates, such as PE-PEO, PEO-PCL, PEO-PLLA, PE-PEO-PLLA and PE-PEO-PCL,
to successfully fabricate a series of mesoporous materials, for example, mesoporous
silicas, mesoporous phenolic resins and mesoporous carbons by a convenient EISA
method. Firstly, we took PE-PEO as model block copolymer to study the
TEOS-to-template or HCl-to-template weight ratio effect during the EISA process, view
from the thermal dynamic point and kinetic reason, respectively. In addition, we
expended the research method to the other block copolymer systems, especially for the
unusual ABC type triblock copolymers, we obtained the hierarchical mesostructure by
single template. Furthermore, the lab-made amphiphilc block copolymer that
synthesized from ring-opening polymerization (ROP) could increase the possibility of
the mesoporous materials field by tuning the segment length through synthesis
technique. Moreover, blending technique could also be used in the templating process
during EISA, the clear method could easily control the morphology and pore size of the
mesoporous materials. Eventually we take our mesoporous thin film as the volatile
organic compounds (VOCs) sensors and obtain great results due to the large surface
area of the mesoporous materials
