查询词典 composite hypothesis

Materials and methods: The composite was respectively prepared by blending Lysine, Histidine, Arginine with PLGA, while the composite respectively prepared by blending Algin, chitosan, NaHCO3 with PLGA as the comparison and the pure PLGA as the control. All composites were degradated in tri-distilled-water at 37℃ for 7 weeks. The degradation property of PLGA with the addition of basic additives was investigated by using gross observation, the pH change of degradation solution and the mass loss ration of the composite.

Poly/melamine cyanurate composite latex particles are prepared via soapless emulsion polymerization. XPS data and TGA analysis reveal that MC particles are encapsulated by PMMA during polymerization, resulting in the formation of a core-shell structure of PMMA/MC composite latex particles. MC can affect the thermal degradation and promote the charring of PMMA. The application of PMMA/MC in nylon 6 (PA6) indicate that the composite latex particles can improve the mechanical pro...

采用原位乳液聚合法制备了聚甲基丙烯酸甲酯/三聚氰胺氰尿酸盐复合胶粒，对其进行X光电子能谱及热重分析结果显示，在MC阻燃剂颗粒表面覆盖了一层PMMA胶膜，形成了具有核-壳结构的PMMA/MC复合胶粒；MC能影响PMMA的热降解过程并促进其成炭；在尼龙6(PA6)中的应用结果表明，PMMA/MC复合胶粒能改善PA6的力学性能和阻燃性能。

In the aspects of research method, we took the method of preparing sol at first and then impregnating the wood to obtain ceramic-wood composite; this method made the wood use efficiently and increased the wood's weight gain percent. The ceramic-wood composite with performances of well decay resistance, dimensional stability, effloresce resistance and high strength was obtained by importing the cymene to the net of gel as the result of co-hydroxylation between MTES and TEOS. Making use of XPS ,we found that the apex of Si2p、O1s、C1s had evident chemical shift , which validated the existence of Si-O-C bonding.Key Words: Sol-gel, Ceramic-wood composite, Modified sol, Ecomaterials
