manufacturing and characterizing of interpenetrating polymer network films based on carboxymetheyl cellulose and tetraethylorthosilicate

In this research, by using tetraethylorthosilicate (teos) and carboxymethyl cellulose (cmc), one of theetheric cellulose derivaties, semi-ipn composites in the form of polymer thin layer films were prepared. the study of the optimal sample which was made up of l/1 ratio of cmc and teos with thickness of 0.3mm showed thesmart abilities like,swelling in alkaline ph and deswelling in acidic liquid mediums with dynamic swelling. the results of this studyrevealed that fabricated ipns could be a suitable substrates because of ph responsibality, biocompatibility and flexibility in mixing with other agents.
