| 摘 要： | 采用注射成型的方法制备了聚乳酸/废旧报纸回收纤维复合材料，探讨了马来酸酐接枝聚丙烯改性处理和1 %的NaOH改性处理对复合材料性能的影响。结果表明，在复合材料中加入2 %的马来酸酐接枝聚丙烯后，聚乳酸与废旧报纸回收纤维的相容性得到改善，复合材料的力学性能得到提高。废旧报纸回收纤维经1 %的NaOH处理后，与聚乳酸的界面被优化，纤维的相对结晶度增大，二者的黏结性能得到改善，复合材料的力学性能也会得到提高。

| Abstract: | The composites of waste newspaper recycled fiber(NRF) and poly(lactic acid)(PLA) were prepared via injection molding technology,and were further modified with MAPP or NaOH.It showed that,addition of 2 % MAPP improved the compatibility of PLA and NRF,and mechanical properties of the composites were enhanced.After NRF was treated with 1 % NaOH,crystallinity of NRF increased,surface bonding between NRF and PLA was improved,also resulted in the increase of mechanical properties of the composites. |
