[0033]Put sodium alginate and water in a No. 1 beaker at a mass ratio of 1:95, stir with a glass rod for 30 minutes, and let it swell for 5 hours. ℃, the rotation speed is 500r / min, heat and stir to dissolve for 60min to obtain sodium alginate solution; put chitosan and water in a No. 2 beaker with a mass ratio of 1:100, stir and mix with a glass rod for 20min, Let stand to swell for 4 hours, then add chitosan enzyme with 0.08 times the mass of chitosan, and place the No. After stirring the enzymolysis for 5 hours, raise the temperature to 95°C, keep warm for 15 minutes to inactivate the enzyme, and wait for natural cooling to room temperature to obtain the modified chitosan liquid; place the aluminum nitride whiskers in a ball mill for ball milling, and pass through a 100-mesh sieve to obtain a refined chitosan solution. Aluminum nitride whiskers, put aluminum nitride whiskers and paraffin wax in a ball mill at a mass ratio of 1:10, mix and ball mill them, and pass through a ...
