本工作较深入地描述了负载型铌氧化物催化剂表面相互作用，为深刻认识负载型铌氧化物催化剂酸催化作用和进行高效固体酸催化剂的设计和制备提供了参考依据。

After removing the catalyzer by dense muriatic acid, carbon nanotubes are reacted with mix acid (vitriol:nitric acid=3:1 vol./vol.). By comparing the surface image of gained carbon nanotubes under the different condition, the best mix acid oxidation temperature is fixed on 140°C and the reaction time is 30min. The soluble carbon nanotubes were prepared by decorating of octadecylamine on the surface of nanotubes. Three processes of grafting were investigated in this research.

The results indicated that both weight and mechanical property of resins decreased by environmental complex fungouds,the weight losses of sheets of gels in 60d were 9.41%、20.65% and 18.60%,the deformation ratios of sheets of gels were 23.5%,25.1% and 26.4% respectively. Mono-germ and mono-fungus tests showed obvious growth of fungoids on the surface of SA/NaAA/AM and SA/NaAA/PVA gels,and slight growth on the surface of SA/NaAA gel.

研究结果发现，环境混合霉菌降低了海藻酸钠复合吸水树脂的质量和力学性能，60d试片失重率依次为9.41%、20.65%和18.60%，试片的破坏形变百分率下降依次是23.5%、25.1%和26.4%；单一细菌和真菌降解实验显示，菌群在含有AM和PVA的SA/AA/AM和SA/AA/PVA凝胶中呈现中度或深度生长状态，在SA/AA凝胶表面呈现轻度生长。

Firstly, micron-size monodisperse polystyrene particles were prepared by emulsifier-free polymerization. Then the photo-initiator with double bond and ester group were attached on the surface of the PS particles by copolymerization using "starve" addition together with styrene. Finally both poly and poly(N-isopropylacrylamide) as hybrid hairy homopolymers were grafted on the surface of the PS particles by "grafting from" photo-initiation with sequential addition of AA and NIPA.
