Intercalative Polymerization

Epoxy resin/ montmorillonite (EP/MMT) composite was prepared via monomer insert in-situ polymerization. It was shown that the EP/MMT composites could be successfully synthesized from the raw materials only by one step, making it simpler than traditional in-situ intercalative polymerization method. The d001 spacing of montmorillonite was tested by XRD and increased to 4.30nm. The results showed that tensile strength and impact strength were improved by 98.11 and 93.69%, respectively. The glass transition temperature was increased by 17.3 °C.

Modified Epoxy

P(BA-St), a good modifier for epoxy resin, was prepared by BA and St in situ polymerization. The modified resin system was based on diglycidyl ether of bisphenol and methyl tetrahydrophthalic anhydride, tris (dimethylaminomethyl) phenol. The influence of the copolymer on mechanical properties and thermal performance of the systems was studied. When 15 wt% of the BA/St with a weight ratio composition of 7.5/7.5 was added to epoxy, high performance modified epoxy resin was obtained.

Electrode Technique

Self-healing materials offer tremendous potential for providing long-lived structural materials. In this study, isophorone diisocyanate (IPDI) microcapsules as self-healing materials were synthesized via in situ polymerization. Thermogravimetric analysis characterized the thermal ability of IPDI, microcapsules and microcapsule shells. The morphology of microcapsules and microcapsule shells were characterized by FE-SEM. Scanning micro-reference electrode technique demonstrated that epoxy resin coatings with IPDI microcapsules on the surface of reinforcing steel Q235 could cure the scratched crevice by immersion in 0.01 M NaCl solution after the coating was scratched. The self-healing epoxy resin coating could protect Q235 from corrosion.
