概要(目的・用途・実施内容)/ Abstract (Aim, Use Applications and Contents)
The purpose of this experiment is to compare the chemical bond between the neat and nano-silica modified epoxy resin.
実験 / Experimental
結果と考察 / Results and Discussion
The XPS spectra were examined to determine whether the incorporation of nano-silica affected the chemical structure of the epoxy resin. Results show the C1s core-level spectra of the neat epoxy resin and nano-silica modified epoxy resin. The XPS spectra of both specimens exhibited two fitted peaks at 284.8 eV and 286.4 eV, attributed to C–C/C–H and C–O bonds, respectively. In the epoxy resin sample modified with nano-silica, no significant peak was observed at 284.2 eV (C–Si bond). With the proportion of nano-silica growth, there is still no cpnpiscouos change in C1s core-level spectra of modified epoxy resin, we can draw a conclusion that nano-silica did not establish noticeable covalent bonding with the epoxy resin backbone.
