Conformal Internal Coating of Macroporous Co-continous MCF-silicas with Isocyanate Derived Polymers
Abstract
The mesoporous surfaces of silica-derived co-continuous mesoporous cellular foams (MCFs) have been conformally coated with isocyanate derived polymers, in analogy to polymer crosslinked silica aerogels. The resulting materials undergo minimal shrinkage upon drying with SCF-CO2, they require no calcination, they are extremely robust, and although their density has increased 3-fold by the polymer uptake, nevertheless, they retain all the macroporosity and 92% of the mesoporous surface area of their native counterparts. Based on those properties, we expect that such polymer-modified mesoporous cellular foams will find applications as platforms for separations.
