Progress of Boron Nitride Nanosheets Used for Heavy-duty Anti-Corrosive Coatings

Abstract

Boron nitride nanosheets (BNNSs), also known as "white graphene", is an important nanofiller with excellent mechanical properties, thermal conductivity, abrasion resistance, barrier properties, and hydrophobicity. It is also a new type of excellent performance insulation materials. It is widely used in heavy-duty anti-corrosion coatings, lubricants, sensors and other fields. Based on the huge application prospects of BNNSs in the field of metal corrosion protection, this article systematically summarizes the preparation and surface functionalization of BNNSs, boron nitride thin film protective coatings, BNNSs/organic protective coatings, BNNSs-inorganic materials/organic protective coatings, and focuses on the detailed analysis and existing problems of BNNSs uniformly dispersed in organic coatings and used for metal corrosion protection. The future development of BNNSs-based anticorrosive coatings is prospected.
