【摘要】 将C60 掺入聚甲基丙烯酸甲酯形成C60 复合材料。研究了其折射率与温度变化的关系 ;随加入C60 量不同 ,导致折射率有不同的变化 ;并研究了该复合物经紫外线照射后的折射率变化。结果表明 :掺入C60 的聚甲基丙烯酸甲酯折射率比纯聚甲基丙烯酸甲酯折射率明显提高。此种C60 复合物的折射率随温度升高而降低 ,而且C60 含量越高 ,折射率对温度变化越敏感 ;经紫外线照射后的C60 复合物的折射率对温度的变化更加敏感更多还原

【Abstract】 The experiment makes C 60 composite material by mixing up C 60 and polymethyl methacrylate Then three minor studies are conducted :(1) Studying the relation of refractivity of the material with the change in temperature (2) Studying the different change in refractivity with different amount of C 60 in the composite material (3)Studying the change in refractivity of the material radiated with ultraviolet radiation A comparison is made between the above three cases The result shows that:under different circumstances, the change in refractivity with the change of temperature differ更多还原
