Improvement of anti-swelling property and anticorrosion performance of epoxy coatings by the introduction of nanocrystalline cellulose composite.

In this work, the effect of nanocrystalline cellulose (NCC) as a nanofiller on the corrosion protection of epoxy resin coatings was examined. To solve problems like poor solvent swelling resistance and micropore formation during the solidification and shrinkage of epoxy resin coatings, NCC was modified with a silane coupling agent. Alkyl chains and active amine groups were grafted onto its surface, improving the dispersibility of NCC in organic solvents and its bonding with epoxy resin.

Research on the Performance of Modified Nanocrystalline Cellulose Reinforced Waterborne Epoxy Coatings.

This study addresses the critical challenges of long-term protection and mechanical stability in waterborne epoxy resin (WEP) coatings by developing composite systems reinforced with modified nanocrystalline cellulose (NCC). Through surface functionalization of NCC using hexadecyltrimethoxysilane (HDTMS) and -[3-(trimethoxysilyl)-propyl]-ethylenediamine (TMPEDA), we synthesized Si-NCC/WEP coatings with enhanced interfacial compatibility and tailored physicochemical properties. Comprehensive characterization via FTIR, AFM, and EIS revealed that the 1% Si-NCC/WEP coating exhibited optimal performance, achieving a 251% increase in Young's modulus (6.
