Study on Curing Mechanism of Hyperbranched Polymer Modified Carbon Nanotube/Epoxy Resin Composites Based on Two-dimensional Correlation Infrared Spectroscopy
摘要
Abstract
To clarify the curing mechanism of hyperbranched polymer modified carbon nanotubes/epoxy resin composite materials and the influence mechanism of different hyperbranched polymers on the curing behavior of epoxy resin matrix,a moving window two-dimensional correlation infrared analysis method was used,and a comparative analysis was conducted on the changes in characteristic functional groups of hyperbranched polyester modified carbon nanotubes/epoxy resin composite material(EP/MWCNTs H204)and hyperbranched polyamide modified carbon nanotubes/epoxy resin composite material(EP/MWCNTs N103)during the heating and curing process.The sequence of changes in each functional group was discussed in detail using generalized two-dimensional correlated infrared analysis.The influence of the introduction of different hyperbranched polymers on the curing behavior of epoxy resin composites was reasonably explained.关键词
