Effect of different fillers on the biodegradation rate of thermoplastic starch in water and soil environments

Popis výsledku v původním jazyce

This work investigates the efect of fller type on the rate of biodegradation of thermoplastic starch-based flms in water and soil environments. The authors applied the casting method to create flms of thermoplastic starch, based on waste paper, flled with clays or organic fllers. Since such materials made from cellulose tend to absorb water, we hydrophobized the surfaces of the flled thermoplastic starch samples. The structures of the blends were characterized by infrared spectroscopy, while atomic-force microscopy was applied to observe change in surface topography and the distribution of the fller. We also studied moisture resistance of the blends. Biodegradation tests revealed that surface topography, distribution of the fller and starch-to-fller interactions were non-critical to the rate and degree of biodegradation of the blends. The biodegradation rate of the blends was strongly afected by the environmental conditions (relative humidity 54%, 100%, respectively; temperature 25 °C, 37 °C, respectively). Under anaerobic conditions, it was the mixtures that biodegraded to the greatest extent, whereas the hydrophobized mixtures did so the least.
