摘　　要：采用热/UV双重固化方式制备高透光率、高雾度光学扩散膜扩散涂层。分别研究了不同树脂/粒子比例(以热固化树脂为参考)、双重固化树脂比例(UV固化树脂/热固化树脂),以及相同树脂/粒子比例条件下不同粒子粒径等参数对光学扩散膜扩散涂层力学性能、光学性能的影响。对制备的光学扩散膜扩散涂层力学、光学性能及表观形貌进行表征。测试结果表明:使用合适比例的热/UV混合固化树脂,能够制备出具有耐划伤性能且翘曲度较低的光学扩散膜扩散涂层。A kind of high light transmittance and high haze diffusion optical light diffusion film was prepared using thermal/UV dual curing methods. The influence of the different resin/ particle ratio（base on the thermosetting resin）, the ratio of dual curing resin（ UV Curing res- in/thermosetting resin） and different size particles with the same resin/particle ratio on the mechanical properties and optical performance of optical diffusion film diffusion coating were studied, respectively. The particle size and its distribution was tested, optical properties and surface morphology of the optical light diffusion coating were characterized. The test results showed that, a kind of anti - scratch diffusion coating of optical light diffusion film which possesses low curl value could be produced when using proper ratio of dual curing resin.
