Abstract
|
Anovel strategy was design and applied for the fabrication of an epoxy resin nanocomposite
containing epoxidized novolac (ENR), epoxidized poly(vinyl chloride) (EPVC) and modified silica
nanoparticles (M-SiO2 NPs). For this purpose, novolac was epoxylated through the functionalization
with epichlorohydrin in super basic medium to produce ENR. The EPVC was synthesized through the
allylation of PVC using allyl alcohol followed by oxidation of allyl groups with meta-chloroperoxybenzoic
acid (m-CPBA). The amine-modified SiO2 NPs (7 wt%) in the presence of a small amount of
ethylenediamine (EDA; 3 wt%) were applied as curing agents for curing a mixture of ENR (70 wt%)
and EPVC (20 wt%) in order to afford a C-ENR-EPVC/SiO2 nanocomposite. The morphology and
thermal stability of the fabricated nanocomposite were investigated using transition electron
microscopy (TEM) and thermogravimetric analysis (TGA), respectively. As the thermal property
studies results, the addition of EPVC as well as curing of mixture using amine-modified SiO2 NPs has
synergistic effect on the thermal stability of theENR resin.
