Chitosan-silica porous hybrids were prepared by a novel strategy in order to improve the mechanical properties of chitosan (CHT) in the hydrogel state. The inorganic silica phase was introduced by sal-gel reactions in ...
Hybrid porous membranes of polycaprolactone (PCL) and silica were obtained by a two stage procedure. First a porous PCL membrane was produced by freeze extraction technique and then a sol-gel reaction was used to form a ...
A novel approach to reinforce polymer porous membranes is presented. In the prepared hybrid materials, the inorganic phase of silica is synthesized in-situ and inside the pores of aminolyzed polylactic acid (PLA) membranes ...
