NOVELTY - Nano-graphene modified cyanobacteria composite bioplastics comprises 130-135 pts. wt. cyanobacteria, 9-10 pts. wt. Lactobacillus delbrueckii, 7-8 pts. wt. blood red mycelia spores liquid, 16-17 pts. wt. lactose, 9-10 pts. wt. nano-graphene, 10-11 pts. wt. konjak glucomannan, 50-55 pts. wt. pearl fiber, 56-67 pts. wt. bamboo fiber, 24-25 pts. wt. shell powder, 8-9 pts. wt. vinyl methoxysilane, 7-8 pts. wt. polyvinyl alcohol and water. USE - Nano-graphene modified cyanobacteria composite bioplastics. ADVANTAGE - The bioplastics is biodegradable, has strong toughness, good tensile property and enhances biological plastic barrier performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the preparation of nano-graphene modified cyanobacteria composite bioplastics comprising mixing konjak glucomannan, nano-graphene, lactose and 2 times water, homogenizing, spray drying, mixing Lactobacillus delbrueckii, blood red mycelia spore liquid, lactose and 0.5 times water, mixing, activating at 30 degrees C, mixing, drying to obtain microencapsulated compound powder, fermenting, adding blue algae, removing sediment, adding 5 times water, mixing, using 600W ultrasonic-assisted wall treatment for 1 hour, sterilizing culture medium, fermenting at 25 degrees C, filtering, mixing to obtain high lactic acid conversion rate of cyanobacteria fermentation compound reserve, baking, pulverizing to obtain cyanobacteria fiber, mixing, concentrating at 80 degrees C for 50 minutes, heating inert gas nitrogen at 160 degrees C under 160 Pa, decompressing at 220-260 degrees C, performing polycondensation under 133 Pa to obtain modified polylactic acid, adding pearl fiber to modified polylactic acid, bamboo fiber, shell powder, vinyl methoxysilane and seaweed fiber, mixing at 70-75 degrees C at 600-700 revolutions per minute for 20-30 minutes to obtain a suspension, adding polyvinyl alcohol, mixing, extruding, granulating and stretching into films.
