摘 要：
一种新型的纳米级有机/无机杂化材料——多面体低聚倍半硅氧烷(POSS)引起了人们的广泛关注。向聚合物体系中加入很少量的POSS便会使复合材料的性能得到明显提高。首先利用顶角-盖帽法合成POSS,用其改性水性聚氨酯木器漆。采用FT-IR、TGA、XRD对复合材料进行表征,并且测量复合材料在室温下接触角。结果表明,POSS能够均匀地分布在漆膜中,形成有机-无机互穿网络结构。此外,POSS的加入提高漆膜的耐热性能,增加涂膜的疏水性。漆膜的机械性能除附着力外均有所提高。

摘 要：
A new organic / inorganic hybrid material with nanoscale sizes,polyhedral oligomeric silsesquioxane( POSS),has attracted wide concerns. The performance of the composite was markedly improved after adding only small amounts of POSS to polymers. In this paper,firstly,POSS was synthesized by using"corner-capping"method,and then waterborne polyurethane wood coatings were modified. The composite was characterized by fourier transform infrared( FT-IR),thermo gravimetric analyzer( TGA) and X-ray diffraction( XRD). The contact angles were measured at room temperature. The results showed that POSS was evenly dispersed in paint film,and formed a net structure with organic and inorganic penetrating together. In addition,the heat-resisting and hydrophobic ability of paint film were improved after adding POSS. The mechanical property was increased except adhesion.
