Adhesion and Surface Issues in Biocomposites and Bionanocomposites

Cintil Jose, Merin Sara Thomas, B. Deepa, Laly A. Pothan, Sabu Thomas.


Abstract

Biopolymers and biocomposites draw our attention in various applications due to their versatile properties. But the lack of good interfacial adhesion between the hydrophilic filler particles and hydrophobic polymer matrix make these composites less attractive for various applications. The use of adhesion promoters, additives or chemical modification of the filler surface can help to improve the interfacial adhesion between filler particles and polymer macromolecules and their dispersion in the matrix, and thus improve the overall mechanical performance of the composites. Interfacial adhesion between filler and matrix remains the key issue in terms of overall performance, since it influences the final properties of the composites. This review focuses on biopolymers, biomatrices, their modifications and processing techniques and characterization of interfacial modifications.

Key words: Biopolymer; biocomposites; bionanocomposites; composites; interfacial adhesion
