电子束固化 PVP 非共价功能化碳纳米管/环氧树脂
Electron Beam Cured PVP Non-Covalent Functionalized Multi-Walled Carbon Nanotubes/Epoxy Composites
摘要
Abstract
In this paper, multi-walled carbon nanotubes (MWNTs) were functionalized with PVP, and then the PVP functionalized MWNTs (PVP-MWNTs)/epoxy composites were prepared by the electron beam in-situ curing. The PVP-MWNTs were characterized by IR spectroscopy and TGA. The results showed that the MWNTs were sucess-fully coated with PVP, and the PVP-MWNTs showed improved dispersion stablity in the epoxy resin. The tensile modulus of the 0.1 wt% PVP-MWNTs/epoxy composites was enhanced by 25%. Dynamic mechanical analysis studies also revealed that the addtion of PVP-MWNTs can improve the storage modulus of epoxy matrix.关键词
