Silanization of nanographene platelets improves interaction with dentin bonding resin matrix and enhance interfacial bond integrity to dentin

Research output: Contribution to journalArticlepeer-review

Abstract

This study synthesized and characterized graphene nanoplatelets silanized with 3-(trimethoxysilyl)propyl methacrylate (MPS-GNP) for morphological and chemical characteristics. In addition, we modified dentin bonding agent using different concentrations of MPS-GNP to study its interaction within the resin matrix of adhesive, degree of conversion (DC), biological, and mechanical properties after bonding to tooth. Both 0.25% and 0.5% MPS-GNP-modified bonding agents showed comparable DC values to the unmodified control adhesive (range: 41%–43%). However, a statistically significant reduction in the DC was found when 0.25% and 0.5% non-silanized GNP was doped with adhesive (
