Polymer-Clay nanocomposites with improved thermal and physical properties by free radical polymerization

A huge interesting to use the Poly(N-vinylcaprolactam) (PNVCL) as thermoresponsive polymer in the biomedical applications, mainly in drug delivery systems. The Poly(N-vinylcaprolactam) (PNVCL) are show a lower critical solution temperature (LCST) as a temperature responsive polymers which ranging fr...
