6 Lignin Reinforcement in Thermoplastic Composites

Lignin has been investigated as a matrix, reinforcing filler, and a coupling agent in various thermoplastics. Mostly, it has been examined with polypropylene and polyethylene matrices. Several properties of thermoplastic composites and blends have been evaluated focusing on the influence of lignin addition at their various concentrations. This chapter will present a literature review of lignin incorporation in thermoplastics.
