What is it about?

The interest is rapidly growing to use green and renewable polymers for engineering applications. Herein, biopolymers have shown great potential as environmentally friendly alternatives. Lignin is one of the most abundant biopolymers obtained from lignocellulosic biomass. Lignin constitutes approximately 15–35% of the lignocellulosic biomass. It has unique properties, such as high carbon content, high thermal stability, adhesive properties, biodegradability, biocompatibility and biological activities. Lignin has also the benefit of cost-effective processing with low energy requirements as a by-product of agricultural, paper and pulp industries. Taking account of these properties, a significant amount of research has been carried out toward the fabrication of advanced lignin-based materials with functional properties to be evaluated in several industrial applications for the last few decades. In recent years, lignin composites have gained popularity in the biomedical applications including tissue engineering scaffolds, wound dressing materials, drug delivery carriers and other medical applications. The studies have shown the suitability of lignin composites for multiple biomedical proposes. The present chapter presents a widespread overview of current achievements, limitations and future perspectives of lignin composites in biomedical field.
