Abstract
Biobased composite materials have been of great interests in recent years because of the need for environmentally friendly alternatives to traditional petroleum-based plastic materials. Among potential renewable materials in eco-friendly markets, starches are considered relatively abundant and inexpensive biopolymers with good biodegradability and biocompatibility. In the presence of plasticizers, starches can be engineered using conventional thermoplastic techniques, e.g., extrusion and injection molding. However, starch-based materials have some limitations due to their inadequate mechanical properties and moisture sensitivity. The blending of nano-sized layered silicates into a starch matrix provides a range of improved properties (increased stiffness, barrier, and thermal stability). In the recent years, new modification reactions and engineering methods have been developed to increase the interfacial interaction between starch polymers and layered silicates. Using novel additives such as plasticizers and compatibilizers could facilitate the dispersion of layered silicates in the polymeric matrix and lead to starch-layered silicates with improved performance. This article covers important topics in the field of starch-layered silicate materials and also reports the most recent progress in the technologies and performance of starch-layered silicate nanocomposites. © Springer-Verlag Berlin Heidelberg 2014.
