Recent coating advances in polybenzoxazine nanocomposites

Abstract

ABSTRACT Polybenzoxazines (PBz) are advanced thermosetting phenolic resins with many advantages, including producing nontoxic by-products, molecular design flexibility, minimum shrinkage, and low water absorption. Nevertheless, some issues might occur when synthesizing PBz, such as their brittleness, which necessitates the incorporation of some additives, such as adding another polymer or some nanocomposite material to enhance the performance of PBz. Polymer nanocomposites have emerged as multifaceted and advanced materials in recent years to overcome the disadvantages of PBz. The development of polymer nanocomposites has broadened the scope of possible uses for coatings and adhesives. Researchers constantly discover new methods for creating polymer nanocomposite coatings. The modification of fillers and the manufacturing processes used determine the properties of polymer nanocomposite coatings. Depending on various features and application types, polymer nanocomposite coatings can be classified into conductive, biocompatible, and intelligent nanocomposite coatings. Nanocomposite adhesives can be classified based on their specific performance features, such as structural, biomimetic, pressure-sensitive, and conductive. The use of newly produced polymer nanocomposites has become increasingly common in several areas of modern technology, including applications such as corrosion protection and accelerated regeneration of biological tissue. The use of polymer nanocomposites has resulted in a substantial revolution in coatings and adhesives. This review aims to shed light and provide information on using polybenzoxazine nanocomposites and their most recent coating implementation.
