Abstract

The coating industry may comply with new safety rules by using more environmentally friendly and harmless alternative materials. The present study intends to investigate the characteristic of agricultural waste material-based bio-polyol derived polyurethane wood protective coating for building and construction applications. This study covers the synthesis and characterization of cardanol based bio-polyol through dual epoxidation of phenolic -OH and terminal unsaturation to generate monoglycidyl ether of cardanol followed by ring opening reaction. The resultant bio-polyol is used for formulation of polyurethanes using aliphatic (Desmodur N75) and aromatic (Desmodur L75) isocyanates. The formulated polyurethanes employed for sustainable wood protective coating as well as architectural and multitudinous applications with enhanced antibacterial activity. The resultant wood protective coating was characterized by attenuated total reflectance-fourier transform infrared spectroscopy (ATR-FTIR), mass spectroscopy, 1 H NMR, thermogravimetric analysis (TGA), surface morphology, mechanical and antibacterial properties.

期刊介绍： Polymers from Renewable Resources, launched in 2010, publishes leading peer reviewed research that is focused on the development of renewable polymers and their application in the production of industrial, consumer, and medical products. The progressive decline of fossil resources, together with the ongoing increases in oil prices, has initiated an increase in the search for alternatives based on renewable resources for the production of energy. The prevalence of petroleum and carbon based chemistry for the production of organic chemical goods has generated a variety of initiatives aimed at replacing fossil sources with renewable counterparts. In particular, major efforts are being conducted in polymer science and technology to prepare macromolecular materials based on renewable resources. Also gaining momentum is the utilisation of vegetable biomass either by the separation of its components and their development or after suitable chemical modification. This journal is a valuable addition to academic, research and industrial libraries, research institutions dealing with the use of natural resources and materials science and industrial laboratories concerned with polymer science.
