Optimization of stable recipe of semi interpenetrating polymeric network based on the diffusivity and swelling percentage

Abstract

The hydrophilic nature of semi interpenetrating polymeric network hydrogels (SIPN) bestows a wide spectrum of applications of such systems establishing it as a remarkable material in polymer technology. A SIPN of Polyacrylamide and Glutaraldehyde mediated crosslinked Poly Vinyl Alcohol can be synthesized with variety of combinations of the basic constituents with variable state parameters. In this work we report the fabrication of SIPN matrix hydrogel prepared as small cylinders of length about 2.0 cm and diameter about 0.8 cm in which the constituents are varied in a sequential manner to attain the optimum parametric condition of state of Acrylamide, Glutaraldehyde and Poly Vinyl Alcohol established on the basis of water transport properties based on the diffusivity and swelling percentage studies of the SIPN prepared. We believe this study will pave the way to a new methodology to achieve optimum conditions of precursors in SIPN.
