Hollow glass microspheres (HGMs)/epoxy syntactic foam were reinforced by hybrid functionalized carbon nanotubes that were synthesized by simultaneous covalent and noncovalent functionalization of carbon nanotubes. The effect of hybrid functionalized carbon nanotubes on density, mechanical properties, and water absorption of HGMs/epoxy syntactic foam was studied. The study indicated that the dispersion of carbon nanotubes in epoxy resin can be improved by hybrid functionalization. The compression strength of syntactic foam reinforced by hybrid functionalized carbon nanotubes was significantly enhanced. The maximum compressive strength of syntactic foam corresponding to chitosan modified carbon nanotubes approached 60 MPa. Hybrid functionalized carbon nanotubes had little effect on the water absorption ability of syntactic foam, and was less than 1%. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

杂化功能化碳纳米管增强复合泡沫的性能研究

中空玻璃微球（HGMs）/环氧复合泡沫材料通过杂化功能化碳纳米管得到增强，该杂化功能化碳纳米管是通过同时对碳纳米管进行共价和非共价官能化而合成的。研究了杂化功能化碳纳米管对HGMs /环氧复合泡沫塑料的密度，力学性能和吸水率的影响。研究表明，通过混合功能化可以改善碳纳米管在环氧树脂中的分散性。杂化功能化碳纳米管增强的复合泡沫的压缩强度得到显着提高。与壳聚糖改性的碳纳米管相对应的复合泡沫的最大抗压强度接近60 MPa。杂化功能化碳纳米管对复合泡沫材料的吸水率影响不大，小于1％。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48586。
