TEMPERATURE-SENSITIVITY OF PU/PNIPAM SEMI-IPN MICROPOROUS MEMBRANES

Drug release of pH/temperature-responsive calcium alginate/poly(N-isopropylacrylamide) semi-IPN beads.

A series of semi-interpenetrating, polymer network (semi-IPN), hydrogel beads, composed of calcium alginate (Ca-alginate) and poly(N-isopropylacrylamide) (PNIPAAM), were prepared for a pH/temperature-sensitive drug delivery study. The equilibrium swelling showed the independent pH- and thermo- responsive nature of the developed materials. At pH=2.1, the release amount of indomethacin incorporat...

Microporous Silica Based Membranes for Desalination

This review provides a global overview of microporous silica based membranes for desalination via pervaporation with a focus on membrane synthesis and processing, transport mechanisms and current state of the art membrane performance. Most importantly, the recent development and novel concepts for improving the hydro-stability and separating performance of silica membranes for desalination are ...

Hybrid microporous membranes intended for protective clothing

Self-decontaminating materials are defined as substances or objects designed and fabricated to deactivate pathogenic microorganisms or chemical warfare agents. Self-decontamination makes it possible for continuous protection against toxic materials. In order to develop destructive barriers against biological and chemical air pollutants, protective clothing and membranes using catalytic or enzym...
