[0018] Moso bamboo is pulverized and ball-milled through a 100-mesh sieve to obtain moso bamboo ball-milled particles and the mass ratio is 1:10. Add the moso bamboo ball-milled particles to a 5% sodium hydroxide solution by mass fraction, then heat in a water bath at 75° C., filter and collect the filtered After washing the cake with a mass fraction of 10% sodium hypochlorite solution for 3 times, the washed filter cake was obtained and according to a mass ratio of 1:5, the washed filter cake was stirred and mixed with a mass fraction of 15% acetic acid solution, heated in a water bath at 45°C for 3 hours, and statically Set to cool to room temperature, then centrifuged at 12000r / min for 10min, collected the lower sediment and rinsed with deionized water for 3 times, vacuum freeze-dried and ball milled through a 200 mesh sieve to obtain a ball milled powder; according to the mass ratio of 1:10, the polyzircon Add oxane to the xylene solution, heat in a water bath at 45°C for 1...
