The interest in using cellulosic fiber-type fillers as reinforcing elements in composite materials based on polymeric matrices is constantly growing, mainly because of the many advantages associated with this renewable material. However the preparation of cellulose-based composites is perturbed by the highly hydrophilic character of the fibers, which is associated with a low interfacial compatibility with hydrophobic polymer matrices, as well as with a loss of mechanical properties. In this study, we will describe a new approach for chemically surface modification of a microcrystalline cellulose (MCC) using poly(ethylene-co-glycidyl methacrylate) (PEGMA) to construct an MCC surface anchored by PEGMA. When applied the modified MCC (PEGMA-a-MCC) to high-density polyethylene (HDPE) composite, interfacial adhesion performance between the PEGMA-a-MCC and HDPE matrix showed better and stronger than that of the pristine MCC, which will induce in better mechanical properties of the composites
