NOVELTY - Preparing modified graphene and nano-cellulose composite temperature-sensitive material involves dissolving 20-30 pts. wt. graphene in 100-200 pts. wt. absolute ethanol, adding 2-5 pts. wt. ammonia water rapidly under magnetic stirring, continuously stirring, adding 1-2 pts. wt. decahexaalkyl trimethyl ammonium bromide first dissolving in anhydrous ethanol, adding solution in dropwise manner with rapid stirring, maintaining at 60-80 degrees C, magnetic stirring for 2-5 hours. USE - Method for preparing modified graphene and nano-cellulose composite temperature-sensitive material (claimed). ADVANTAGE - The method enables to prepare modified graphene and nano-cellulose composite temperature-sensitive material in simple manner, cost-effective, which has avoids raw material graphite agglomeration, and has excellent mechanical property. DETAILED DESCRIPTION - Preparing modified graphene and nano-cellulose composite temperature-sensitive material involves dissolving 20-30 pts. wt. graphene in 100-200 pts. wt. absolute ethanol, adding 2-5 pts. wt. ammonia water rapidly under magnetic stirring, continuously stirring, adding 1-2 pts. wt. decahexaalkyl trimethyl ammonium bromide first dissolving in anhydrous ethanol, adding solution in dropwise manner with rapid stirring, maintaining at 60-80 degrees C, magnetic stirring for 2-5 hours, and standing. 0.5-1 pts. wt. nanocellulose is dissolved into 100-150 pts. wt. water, added 0.5-1.5 pts. wt. alkyl phenol polyoxyethylene ether, 2-10 pts. wt. urea, low temperature ultrasonic dispersing, magnetic stirring for 1- 12 hours at 20-30 degrees C, and placing for 2-3 days, and standing. The solution obtain is heated in a water bath at 35-55 degrees C, added 1-2 pts. wt. precursor solution under stirring, kept temperature for 40-60 minutes, added product obtained, maintained temperature, stirred for 10-12 hours, removed cetyltrimethylammonium bromide, centrifuged by using distilled water and alcohol for 3-4 times, and freeze-dried to obtain final product.
