摘要: The phenolic (PF) resins/attapulgite (AT) nanocomposites are synthesized by the in-situ polymerization of which AT was not premodified. Fourier transform infrared spectroscopy (FTIR) study demonstrates that there's no chemical interaction between PF resins and nanoparticles. However, variation peak intensity ratios corresponding characteristic bands suggests there may be hydrogen bonding resins. Phenolic foams also prepared this reinforced PF/AT Scanning electron microscope (SEM) images indicate nanoparticles well dispersed in foams. size distribution foam cells more uniform than neat ones. Thermogravimetric analysis (TGA) indicates initial temperature for major structural decomposition increased ∼20°C when 10 wt% added. influences on mechanical properties investigated. results sh...
