|Abstrakt EN:||Thermoplastic starch is a promising and well studied biodegradable polymeric material of natural provenience. It has potential to replace conventional oil-based non-biodegradable polymers especially in packaging industry. However, often low tensile strength of thermoplastic starch materials requires their reinforcement. It can be performed advantageously using clay or clay minerals, because these materials are able to form nanocomposites with polymer matrix. One particular type of montmorillonite (Cloisite Na®) is usually used in experiments involving starch/clay nanocomposites. This paper deals with thermoplastic starch reinforcement by bentonites as industrial minerals in comparison with conventionally used purified montmorillonite (MMT). Mechanical testing results proved that natural bentonites contribute by similar level of reinforcement to thermoplastic starch matrix as the purified MMT.|
