THERMOSET NANOCOMPOSITES FROM EPOXIDIZED LINSEED OIL FOR STRUCTURAL APPLICATIONS

摘要

In this study, a bio-based epoxy thermoset was made from highly functional epoxidized linseed oil (ELO) using a polyethyleneimine (PEI) crosslinking agent. Following optimization of cure conditions and the stoichiometric ratio of ELO to PEI, the compatibility of this system with several commercial montmorillonite and hydrotalcite layered nanofillers was studied. The hydrotalcites were observed to enhance the homogeneity of the ELO-PEI system, whereas the montmorillonites showed settling and produced inhomogeneous materials in all cases.
