Tóm tắt
The thermal behaviour of bio-fillers and bio-filler/polyolefin composites were studied with thermogravimetric analysis. The thermal analysis of the fillers showed rice husk has thermal resistance comparing to sawdust. In the air atmosphere, the main peak of rice husk degradation shifted to lower temperature values compared to that in nitrogen atmosphere. The residues of rice husk at 700oC in the air atmosphere were lower than that in nitrogen atmosphere. Moreover, the effects of filler type and loading as well as polymer matrix type and modification on the thermal properties of the three composite systems including rice husk/polypropylene composite, rice husk/polyethylene composite and sawdust/polyethylene composite were evaluated. It was found that the thermal stability of the composites decreased with increase of filler loading from 30 wt% to 50 wt%. However, the thermal stability and degradation temperature of the composites with compatibilizers were slightly higher than those of the composites without compatibilizers.
