NOVELTY - Preparing graphitic alkenyl nano-borate composite material involves adding 1 pts. wt. graphene oxide and 1000-3000 pts. wt. water and dissolving to obtain solution, mixing solution with 1-60 pts. wt. alkyl phenol and N,N-dimethyl acetamide and ultrasonically dispersing for 2-3 hours to obtain 0.3-1 milligram/milliliter graphene oxide solution. The reaction mixture is stirred at 80 degrees C, followed by the addition of 20-30 pts. wt. sodium borohydride and sodium mixed solution and stirred for 1-2 hours. 10-1000 pts. wt. hexadecyl calcium borate and nano-cerium borate are stirred for 10-15 hours. USE - Method for preparing graphitic alkenyl nano-borate composite material (claimed). ADVANTAGE - The method enables to prepare graphitic alkenyl nano-borate composite material in simple manner which has mild reaction condition, is easy to realize and convenient to operate. DETAILED DESCRIPTION - Preparing graphitic alkenyl nano-borate composite material involves adding 1 pts. wt. graphene oxide and 1000-3000 pts. wt. water and dissolving to obtain solution, mixing solution with 1-60 pts. wt. alkyl phenol and N,N-dimethyl acetamide and ultrasonically dispersing for 2-3 hours to obtain 0.3-1 milligram/milliliter graphene oxide solution. The reaction mixture is stirred at 80 degrees C, followed by the addition of 20-30 pts. wt. sodium borohydride and sodium mixed solution and stirred for 1-2 hours. 10-1000 pts. wt. hexadecyl calcium borate and nano-cerium borate, are mixed and stirred for 10-15 hours. The reaction mixture is stirred and refluxed on oil bath for 5-20 hours at certain temperature. The mixture is hot filtered, washed and dried to obtain desired product.
