Abstract

The effects of physical properties and molecular structure of 200 nm polystyrene nanospheres (PSN) coated on silicon wafer exposed with daily solar flux were explored by field emission scanning electron microscope (FE-SEM) and attenuated total reflectance-Fourier transform infrared (ATR-FT-IR) spectrometer. It is revealed that the particles shape of PSN changed from spheric to eight-shaped after solar radiation. Reduction of the size as much as 29.5% after 5 minutes exposure was also observed in PSN particles. Changes in the molecular structure of the PSN particles after solar radiation were observed where some of the phenyl moieties of polystyrene broke down to facilitate carbon-carbon cross linkage bonds. These results demonstrated that the shrinkage of PSN particles is caused by the change of the molecular structure of polystyrene.
日晒下聚苯乙烯纳米球物理性质和分子结构的变化
利用场发射扫描电镜(FE-SEM)和衰减全反射-傅里叶变换红外光谱仪(ATR-FT-IR)研究了日晒下硅片表面涂覆200 nm聚苯乙烯纳米微球(PSN)的物理性质和分子结构的影响。结果表明,在太阳辐射作用下,PSN的粒子形状由球状变为八字形。PSN颗粒在暴露5分钟后也缩小了29.5%。在太阳辐射后,PSN粒子的分子结构发生了变化,聚苯乙烯的一些苯基部分被分解以促进碳-碳交叉键的形成。这些结果表明PSN颗粒的收缩是由聚苯乙烯分子结构的变化引起的。
