A polypropylene-grafted poly(hexamethylene guanidine) (PP-g-PHMG)/polyethylene (PE) monofilament was prepared by melt blending and spinning using PE and PP-g-PHMG. The effect of PP-g-PHMG content on the structure, mechanical properties, and antimicrobial properties of PP-g-PHMG/PE alloy monofilaments was studied. Compared with PP/PE without grafting PHMG, of PP-g-PHMG/PE alloy monofilaments increased due to rigidity of PHMG grafted. In the PP-g-PHMG/PE alloy monofilaments, the total degree of crystallinity of alloy monofilaments decreased; hence, the -relaxation associated with the crystalline region of the polymer matrix becomes weaker as PP-g-PHMG content increases. The breaking strength of PP-g-PHMG/PE alloy monofilaments decreased while the knotting strength increased by increasing PP-g-PHMG content. The antibacterial test showed that the PP-g-PHMG/PE alloy monofilament had obvious inhibitory effect on E. coli and Staphylococcus aureus. Therefore, the PP-g-PHMG/PE alloy monofilament has the potential to make green and highly effective antifouling materials.

聚丙烯接枝的聚六亚甲基胍/改性聚乙烯单丝及其抗菌性能

通过熔融共混并使用PE和PP-g-PHMG纺丝来制备聚丙烯接枝的聚（六亚甲基胍）（PP-g-PHMG）/聚乙烯（PE）单丝。研究了PP-g-PHMG含量对PP-g-PHMG / PE合金单丝的结构，力学性能和抗菌性能的影响。与未接枝PHMG的PP / PE相比，PP-g-PHMG / PE合金单丝由于接枝PHMG的刚性而增加。在PP-g-PHMG / PE合金单丝中，合金单丝的总结晶度降低；因此，-随着PP-g-PHMG含量的增加，与聚合物基质晶体区域相关的弛豫变得更弱。PP-g-PHMG / PE合金单丝的断裂强度降低，而打结强度则随着PP-g-PHMG含量的增加而增加。抗菌试验表明，PP-g-PHMG / PE合金单丝对大肠杆菌和金黄色葡萄球菌具有明显的抑制作用。因此，PP-g-PHMG / PE合金单丝具有制造绿色高效防污材料的潜力。
