Study of Microstructure and Dynamic Mechanical Analysis of Biodegradable Tableware Produced with Corn Straw

Abstract:

This paper focused on biodegradable tableware processed with plant fiber, which were obtained by mechanical processing corn straw, abundant in Heilongjiang Province of China. Firstly, the microstructure characteristics of tableware were described by Scan Electronic Microscope (SEM). Secondly, the dynamic mechanical property of biodegradable tableware was analyzed by DMA, which will provide a reference to optimize the biodegradable tableware design in future. And the dynamic mechanical property of biodegradable tableware also was compared with the dynamic mechanical properties of the plastic snack box. The results showed that biodegradable tableware had a highly storage modulus (E′) originally, it was 3216MPa,while the maximum storage modulus (E′) of plastic snack box was 852MPa. And the results also indicated that the treat temperature has a significant effect on the dynamic mechanical properties of biodegradable tableware, as the treat temperature increased closely to 95°C, the biodegradable tableware appeared glassy transition, but the storage modulus (1650MPa) was still much higher than that of the plastic snack box.
