Preparation, characterization, and infrared emissivity property of optically active polyurethane/TiO2/SiO2 multilayered microspheres
Opticallyactive polyurethane/titania/silica (LPU/TiO2/SiO2) multilayered core–shell composite microspheres were prepared by the combination of titania deposition on the surface of silica spheres and subsequent polymer grafting. LPU/TiO2/SiO2 was characterized by FT-IR, UV–vis spectroscopy, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), SEM and TEM
光学活性聚氨酯/二氧化钛/二氧化硅(LPU / TiO 2 / SiO 2)多层核-壳复合微球是通过将氧化钛沉积在二氧化硅球表面并随后进行聚合物接枝而制得的。LPU / TiO 2 / SiO 2的特征在于FT-IR,紫外可见光谱,X射线衍射(XRD),X射线光电子能谱(XPS),热重分析(TGA),SEM和TEM,以及红外发射率此外,还研究了其值(8–14μm)。结果表明二氧化钛和聚氨酯已成功地涂覆在二氧化硅微球的表面上。LPU / TiO 2 / SiO 2展示了明显的多层核壳结构。红外发射率值随覆盖层的增加而降低,因此证明界面相互作用直接影响红外发射率。此外,基于光学活性聚氨酯的LPU / TiO 2 / SiO 2多层微球具有有序的二级结构和增强的界面协同作用。因此,它具有最低的红外发射率值。
