ENVIRONMENT-FRIENDLY SELF-HEALING POLYVINYL ALCOHOL HYDROGELS WITH IMPROVED MECHANICAL PROPERTIES USING CELLULOSE AND METHOD OF PREPARING THE SAME

摘要

The present invention relates to an environmentally friendly self-healing polyvinyl alcohol hydrogel having improved mechanical properties using cellulose and a method for producing the same. More particularly, the present invention relates to a polyvinyl alcohol having improved stress / strain and self-Alcohol (PVA) based hydrogel and a method for producing the same. By including biocompatible cellulose in the self-healing hydrogel, it is possible to produce self-healing polyvinyl alcohol hydrogel not only in strength of the material but also in self-healing ability at the damaged interface by acting as a crosslinking agent of cellulose through hydrogen bonding.;
