R & D needs in the field of clay modified polymeric coatings

Abstract Polymeric coatings play a crucial role in protecting surfaces from various environmental factors, such as corrosion, abrasion, and UV degradation. In recent years, the incorporation of nanoclays into polymeric coatings has gained attention due to their ability to enhance various properties, including mechanical strength, barrier performance, and flame retardancy. The performance of these coatings is significantly influenced by interaction between clay nano particles and polymer matrices, dispersion technique and finally its drying behaviour, which dictates the formation of a continuous and robust film. However, optimisation of polymeric coating using clay as filler for cost reduction and impact of clay modification on the drying kinetics and subsequent film properties of polymeric coatings remains a complex phenomenon and often poorly understood. Also, several other challenges remain, such as optimization of clay within polymer matrices and assessing its long term durability, drying under different environmental conditions. This paper explores the current research & development (R&D) needs in the clay modified polymeric coating and significant opportunity for enhanced cost reduction, performance and sustainability in various industrial applications. The insights gained from this study will contribute to a deeper understanding of the complex interactions between clay-polymer matrices, its optimization, drying behaviour, and coating performance, ultimately guiding the development of more efficient and durable coatings.
