Preparation of easily stripped off temporary wound dressing materials by radiation grafting
摘要
A novel method of preparation of easily stripped off temporary wound dressing material is disclosed. In this process, the-N-isopropyl acrylamide (NIPAAm) monomer is successfully grafted on the non-woven cloths by copolymerization. It is initiated by gamma -ray irradiation to activate the surface of the non-woven cloth. NIPAAm is then grafted onto the surface of the non-woven cloth. The free radical or peroxide is produced by Co-60 gamma -ray, then grafted on the non-woven cloths. The lower critical solution temperature (LCST) in thermoresponsive poly-N-isopropylacrylamide (NIPAAm) is still retained after the grafting. This will make the dressing cloth stripped off easily and without hurting the tissue. The material process is very simple and has medically applicable value.
