对以聚苯乙烯(PS)和自行合成的纳米“类双亲”PMMAPS为光散射剂，以聚甲基丙烯酸甲酯(PMMA)为基体的复合光散射材料进行了实验研究。测试并分析了样品的雾度及透光率与添加量之间的关系，目的在于通过调节散射剂添加量来调控以PMMA为基体的高聚物材料的光散射性能。实验结果表明，添加少量PS到PMMA中即可制备出光散射材料，PS添加量为1%时，复合光散射材料的透光率为80%；不添加PMMAPS时雾度为50%，添加了PMMAPS时雾度达到80%，PMMAPS可以改善PMMA和PS之间的相容性，提高样品的雾度值。因此通过调节散射剂PS和PMMAPS添加量可实现光散射高雾度和高透光率的双高要求。

Compound Light Scattering Materials(LSMs) with polystyrene(PS) as the light scattering agents and Polymethylmethacrylate(PMMA) as the matrix were studied.The relationship between the haze and transmittance of samples and the amounts of agents was analysized for adjusting and controlling the light scattering properties of polymer materials which took the PMMA as the matrix.The results show that LSMs can be obtained with only a small amount of PS dispersed in PMMA. Experimental results also show that the transmittance of LSMs is 80% provided the content of PS is 1%. The haze could be improved from 50% to 80% with the aid of PMMAPS and the PMMAPS is able to increase the haze of LSMs by improving the compatibility between PMMA and PS. Therefore, LSMs with high haze and transmittance can be achieved by adjusting the amounts of PS and PMMAPS.
