New click chemistry scheme towards improvement of filler/polymer crosslinking in bio-based polymer composites

摘要: The current study aims to develop a cutting-edge methodology to enhance compatibility between natural fiber and polymeric matrix in bio-composites. To achieve this, an innovative approach for grafting an azide functional group (Az) onto the surface of polypropylene (PP) was successfully developed and confirmed. The Az group contributed to enhancing the interfacial interaction between the polymer matrix and the bio-filler through chemical crosslinking. Crosslinking is achieved through an innovative and efficient chemical process known as click chemistry. In particular, a click reaction is established between the functionalized PP with an azide group and functionalized natural filler with an alkyne group. The effectiveness of the proposed technique is verified using Fourier Transform Infrared (FTIR) spectroscopy, X-ray Photoelectron Spectroscopy (XPS), Thermo-Gravimetric Analysis (TGA), and Scanning Electron …
