Bio‐Based Hyperbranched Polyurethane Nanocomposites

Abstract

This article describes bio‐based hyperbranched polyurethane nanocomposites with special emphasis on vegetable oil–based polyurethanes. The article also demonstrates the importance of such nanocomposites and the roles of nanomaterials on ultimate performance of such polymeric materials. Materials and methods for preparation of bio‐based hyperbranched polyurethanes and their nanocomposite are also discussed. Fourier transformed infrared spectroscopic, X‐ray diffraction, thermogravimetric analysis, differential scanning calorimetric, scanning electron microscopic, and transmission electron microscopic studies are briefly mentioned to characterize such nanocomposites. Physicomechanical, chemical, thermal, and biological attributes like biodegradability and biocompatibility of the nanocomposites are also demonstrated in this article. The article shows that the fabrication of appropriate nanocomposites of bio‐based hyperbranched polyurethane using suitable nanomaterials is the key guideline to achieve desired performance or new set of exciting performance for such environmentally benign materials. Finally, the article emphasizes various applications of bio‐based hyperbranched polyurethanes and their nanocomposites.
