Embodiment 1
[0027] 1.645g of methyl methacrylate, 0.355g of vinyltrimethoxysilane, 35g of tetrahydrofuran and 0.05g of azobisisobutyronitrile were successively added into the autoclave. Concentrated hydrochloric acid was then added to pH=1. Then, 0.4 g of zirconium n-propoxide, 0.8 g of acetylacetone and 0.5 g of deionized water were sequentially added into the autoclave. Cover the lid, put it into a metal can, put it into an incubator with a temperature of 80° C., and react for 10 hours. After the reaction is completed, the metal tank is completely cooled, and then the reactor is taken out. The prepared product solution was spin-coated on a silicon wafer by using a homogenizer at a rotation speed of 3000 rpm and a spin-coating time of 40 seconds. Then put the coated silicon wafer into an oven at 80°C for 1 hour, at 100°C for 1 hour, and at 150°C for 2 hours for annealing. The obtained film is the polymethyl methacrylate / zirconia composite material.

Embodiment 2
[0030] 1.532g of methyl methacrylate, 0.428g of vinyltriacetoxysilane, 50g of toluene and 0.20g of dicumyl peroxide were successively added into the autoclave. Concentrated hydrochloric acid was then added to pH=1. Then, 2.0 g of zirconium isopropoxide, 4.0 g of benzoylacetone and 1.0 g of deionized water were successively added into the autoclave. Cover the lid, put it into a metal can, put it into a thermostat with a temperature of 100° C., and react for 8 hours. After the reaction is completed, the metal tank is completely cooled, and then the reactor is taken out. The prepared product solution was spin-coated on a silicon wafer by using a homogenizer at a rotation speed of 2500 rpm and a spin-coating time of 60 seconds. Then put the coated silicon wafer into an oven at 80°C for 2 hours, 100°C for 1 hour, and 150°C for 1 hour for annealing. The obtained film is the polymethyl methacrylate / zirconia composite material.

Embodiment 3
[0033]Add 1.546g of methyl methacrylate, 0.521g of γ-glycidyl etheroxypropyl trimethoxysilane, 0.216g of maleic anhydride, 30g of N,N-dimethylformamide and 0.17g of dimethylmethoxysilane in the autoclave Benzoyl. Concentrated hydrochloric acid was then added to pH=1. Then, 1.6 g of zirconium acetate, 3.2 g of dibenzoylmethane and 0.6 g of deionized water were successively added into the autoclave. Cover the lid, put it into a metal can, put it into a thermostat with a temperature of 70° C., and react for 12 hours. After the reaction is completed, the metal tank is completely cooled, and then the reactor is taken out. The prepared product solution was spin-coated on a silicon wafer by using a homogenizer at a rotation speed of 3500 rpm and a spin-coating time of 50 seconds. Then put the coated silicon wafer into an oven at 80°C for 1 hour, 110°C for 2 hours, and 150°C for 2 hours for annealing. The obtained film is the polymethyl methacrylate / zirconia composite material.
