Abstract

The primary aim of this article is to update many important synthetic pathways, properties and applications of the polyurethanes and its composites. Polyurethanes (PUs) are a special group of versatile materials with a great potential for different use in the development of modern, healthy and clean society, including its multifaceted use in the fields of construction and building related work, transportation, furniture and bedding, appliances, packaging, textiles, fibres, apparel, machinery and foundry, electronics, footwear, medical and so forth. Over the last 8-9 decades, several synthetic strategies of the diverse polyurethanes (PUs) are maturely designed and actively executed using various sustainable and non-sustainable methods for miscellaneous applications in different areas. The major advantages of the modern PUs are to impose desired properties in the materials pertinent to the field of work during their preparation by changing a different kind of monomers and additives. Briefly, this review summarizes the overall accounts, importance, synthetic approaches, properties, and miscellaneous applications in the desired scenario in details.

Keywords: Polyurethanes, diisocyanates, polyols, composites, synthesis and applications.
