| Abstract: | The use of disposable chopsticks is very popular in chopsticks-using countries, such as Taiwan, China
and Japan, and is one of the major sources of waste in these countries. In this study, the fiber recycling
from disposable chopsticks was chemically modified by coupling agents. Furthermore, the modified fiber
was added to the biodegradable polymer (polylactic acid, PLA), to form novel fiber-reinforced green
composites. These composites prepared by melt-mixing method, were examined by scanning electron
microscopy, differential scanning calorimetry, thermogravimetric analysis, and mechanical tests. The
results indicated that the Tg of PLA was increased by the addition of fiber, which may improve the heat
resistance of PLA. The thermogravimetric analysis of the composites showed that the degradation process
of fiber-filled systems started earlier than that of plain PLA, but possessed a higher char yield. Mechanical
tests showed that the tensile strength of the composites markedly increased with the fiber content,
reaching 115MPa in the case of being reinforced with 40 phr fiber, which is about 3 times higher as
compared to the pristine PLA. Furthermore, this type of reinforced PLA would be more environmental
friendly than the artificial additive-reinforced one, and could effectively reduce and reuse the waste of
disposable chopsticks. |
