Characterization studies of biopolymeric matrix and cellulose fibres based composites related to functionalized fibre-matrix interface

Abstract

Interfacial bonding between cellulosic fibres and biopolymeric matrices is always an issue when it comes to blending with a different medium in composites. For example, the blending of natural or synthetic fibre with a biopolymer or synthetic polymer composite. Many research presumed that hydrophilic fibre has low interfacial bonding in composites. Nevertheless, there are several techniques that can be used to improve the interfacial bonding of hydrophobic fibre, for instance, through certain chemical treatments for the hydrophilic fibre. Chemical treatments for the fibre involve macro-sized fibre up to the nanocellulose section. The changes include physical and chemical reactions on both fibre/nanocelullose and the matrices of the composites. The transformation of interfacial bonding improvement can be observed either in macro or nano conditions. This chapter will discuss several techniques that were used to observe the changes in interfacial bonding improvement through the use of special types of equipment. © 2020 Elsevier Ltd.
