Microporous Organic Network: Superhydrophobic Coating to Protect Metal–Organic Frameworks from Hydrolytic Degradation
Despite
the rapid development of versatile metal–organic
frameworks (MOFs), the synthesis of water-stable MOFs remains challenging,
which significantly limits their practical applications. Herein, a
novel engineering strategy was developed to prepare superhydrophobic
MOFs by an in situ fluorinated microporous organic
network (FMON) coating. Through controllable modification, the resulting
MOF@FMON retained the porosity and crystallinity of the pristine MOFs.
Owing to the superhydrophobicity of the FMON and the feasibility of
MOF synthesis, the FMON coating could be in situ integrated
with various water-sensitive MOFs to provide superhydrophobicity.
The coating thickness and hydrophobicity of the MOF@FMON composites
were easily regulated by changing the FMON monomer concentration.
The MOF@FMON composites exhibited excellent oil/water separation and
catalytic activities and enhanced durability in aqueous solutions.
This study provides a general approach for the synthesis of superhydrophobic
MOFs, expanding the application scope of MOFs
