Biodegradability of Electron Beam Treated Natural Fibers and Biocomposites |
| 초록 |
Biodegradability of biocomposites and electron beam irradiation effect on natural fiber composting has been studied in order to environmentally friendly natural fiber reinforced polymer composites. For natural fibers, composting tests on the electron beam treated henequen and flax fibers were performed and the biodegradability of raw and 500 kGy electron beam treated flax fibers was also compared. For biocomposites, biodegradability of PHB-Kenaf and PHB-MA-Kenaf composites is compared to the PP-glass composite and also composting test on neat polymer samples such as PHB, PLA, CA-TEC were performed as references. At the end of test period, most of the samples were still actively degrading. Cellulose positive control samples degraded 62% after 60 days. Henequen-EBI 500 fibers are degrading faster than raw henequen fibers, but henequen-EBI 100 degrade slower than raw henequen fibers. Flax fiber and compost mixture degrade slowly as compared to the blank compost; flax-EBI 500 fibers degrade faster than raw flax fibers. PHB-MA-Kenaf composites are degrading slightly faster as compare to PHB-Kenaf composites. Degree of degradation for neat polymer samples is of the following order, PHB ＞ PLA ＞ CA-TEC (least degradable). Maximum amount of degradation for a particular sample can be achieved in a period of four to six months; less time using more active compost. |
