纳米sio2/pmma复合材料的光学性能
DOI: 10.3969/j.issn.1671-7627.2012.04.020, PP. 101-104
Keywords: 复合材料,原位,光学常数
Abstract:
以聚甲基丙烯酸甲酯(pmma)为基体,通过原位复合的方法制备含纳米sio2的复合材料。用紫外-可见分光光度计(uvpc)和傅里叶红外光谱仪(ft-ir)研究复合材料的光谱特性。结果表明:当掺入少量纳米sio2时,复合材料的反射谱峰和透射谱峰均发生一定程度的红移;当纳米sio2含量超过一定量时,复合材料透过率显著降低。此外,依据fresnel’s公式和beer’s定律计算了复合材料的光学常数。
