NOVELTY - Preparation of polylactic acid based adhesive comprises placing 300-400 pts. wt. graphene oxide coated cationic starch in ice-water bath, performing ultrasonic dispersion in 15-25 pts. wt. trichloromethane, adding 3000-4000 pts. wt. polylactic acid and 15-25 pts. wt. trichloromethane, adding citric acid to polylactic acid solution, mixing poured in vessel, placing in ventilated place and volatilizing trichloromethane. USE - Method of preparing polylactic acid based adhesive (claimed). ADVANTAGE - The method has wide raw material sources, low impact on environment, is non-toxic and environment friendly and improve mechanical strength of adhesive and crystallinity and thermal stability of polylactic acid.
