发明名称 NON-DEGRADABLE AND DEGRADABLE POROUS MATERIALS WITH HIGH SURFACE AREAS
摘要 <p>A method for preparing a highly porous, high surface area material comprises steps of mixing a non-degradable polymer with a solvent; gelling the mixture; and treating the gel to form a substantially solvent free porous structure having a porosity greater than about 80 %. The resultant material is mechanically strong and has an architecture selected from nanofibrous, microfibrous, non-fibrous, complex porous structure with nanofibrous architecture, or mixtures thereof. A method for preparing a highly porous, high surface area material comprises steps of mixing a degradable or partially degradable polymer with a solvent mixture comprising a first and second solvent in a first to second solvent ratio higher than 1:1; gelling the mixture; and treating the gel to form a solvent free, mechanically strong, porous structure having a porosity greater than 80 % and having a complex porous structure with nanofibrous architecture.</p>
