Lignin Modification for Enhanced Performance of Polymer Composites.

The biopolymer lignin, which is heterogeneous and abundant, is usually present in plant cell walls and gives them rigidity and strength. As a byproduct of the wood, paper, and pulp manufacturing industry, lignin ranks as the second most prevalent biopolymer worldwide, following cellulose. This review paper explores the extraction, modification, and prospective applications of lignin in various industries, including the enhancement of thermosetting and thermoplastic polymers, biomedical applications such as vanillin production, fuel development, carbon fiber composites, and the creation of nanomaterials for food packaging and drug delivery.

High-compact MXene-based coatings by controllable interfacial structures.

Titanium carbide (TiCT) MXenes have been regarded as important functional fillers of organic coatings for anticorrosion. Various MXene-based composite coatings have been fabricated and investigated a material modification strategy, enhancing the corrosion protection performance. However, the anticorrosion reliabilities of MXene-based composite coatings were thwarted by their disordered interfaces.
