等离子体是继固态、液态、气态之后的物质第四态,当外加电压达到击穿电压时,气体分子被电离,产生包括电子、离子、原子和原子团在内的混合体,等离子体辅助加工被用来制造特种优良性能的新材料、研制新的化学物质和化学过程,加工、改造和精制材料及其表面,具有极其广泛的工业应用--从薄膜沉积、等离子体聚合、微电路制造到焊接、工具硬化、超微粉的合成、等离子体喷涂、等离子体冶金、等离子体化工、微波源。

S3:取适量间甲酚溶液放入反应釜中,将聚酯短纤维B放进反应釜中,60℃-70℃的恒温条件下,搅拌浸泡1.5-2h,水洗风干,得到聚酯短纤维C;
S4:将聚酯短纤维C放进低温等离子接枝设备中,放入聚丙烯和引发剂,进行接枝处理,得到聚丙烯-聚酯短纤维初品;
S5:将聚丙烯-聚酯短纤维初品放进真空干燥箱内,烘干4-5h,得到聚丙烯-聚酯短纤维成品。
优选地,所述S1中浸泡条件为:浸泡温度为20℃,且反应釜内为无光环境。
优选地,所述S4中引发剂为过氧化二碳酸二异丙酯溶液、过氧化环己酮溶液、过氧化苯甲酸叔丁酯溶液和过氧化苯甲酰中一种,优选为过氧化二碳酸二异丙酯溶液。
优选地,所述S5中真空干燥条件为真空干燥箱腔内压强为-0.4MPa~-0.6MPa,温度为100℃-120℃,烘干时间为3-4h。
