| 摘 要： | 阳光中的紫外线是引起高分子材料老化的最主要因素，高分子材料被紫外线照射后发生一系列的光化学反应，导致材料变色、变脆、透明度下降和力学性能降低，缩短了其使用寿命，长期以来，围绕紫外光对高分子材料老化作用的问题，科学工作者进行了广泛的观测和研究。结果表明，在高

| Abstract: | The carbon nanotubes(CNTs) and two types of low density polyethylene(LDPE, DFDA7042 and EF7B) were melting blended and blown into films with thickness 10 μm. The ultraviolet(UV) transparent characteristics and the mechanical properties of the films were investigated. The UV transparency of the films can be reduced significantly when the content of CNTs was very low; the UV transparency of the DFDA7042 film filled with 0 01% CNTs and the EF7B film filled with 0 01% CNTs was decreased by 52.1% and 50.8%, respectively compared to the blank films. CNTs would agglomerate in the LDPE matrix with the CNTs content increasing, which lead to the increase of the UV transparency. |
