| 摘 要： | 用衰减全反射红外光谱(FTIR-ATR)技术研究了纳米SiO2粒子在紫外光固化复合涂层中的迁移现象,并对影响纳米SiO2粒子在涂层中分布梯度的因素进行了半定量分析。研究结果表明,纳米SiO2粒子在光固化过程中向涂层接触空气的表面迁移,在表面层富集。当纳米SiO2粒子含量较高、分子量较小、接枝率较高,或者在极性较大的基体树脂中时,迁移较快,分布梯度较大。

| Abstract: | The migration phenomena of nano-SiO_2 particles in UV cured composite coatings are studied by FTIR-ATR and the factors affecting the distributing gradient of nano-SiO_2 particles in coating are discussed by semi-quantitative analysis. The results show that nano-SiO_2 particles migrate to the surface of composite coatings. The distributing gradient of nano-SiO_2 in the coating is larger when the nano-SiO_2 content or its molecular weight or graft ratio or the polarity of host resin is larger. |
