| 中文摘要: |
| 目的 研究低密度聚乙烯( LDPE) 薄膜经低温等离子体处理前后,表面性能的变化情况。 方法 采用不同的处理条件,对 LDPE 进行低温等离子体处理,并对比 LDPE 薄膜处理前后的表面形貌、表面接触角及剥离强度。 结果 采用空气为处理气氛时,在功率 44 W、真空度 60 Pa 的条件下处理 30 s,LDPE薄膜的静态接触角从处理前的 101 o 降到 13 . 5 o ;等离子体处理后的 LDPE 薄膜在 1 h 内,接触角会迅速上升到 74 o ,失去等离子体处理的效果。 结论 对于处理气氛,空气比 N2 和 CO2 的处理效果更好;等离子体处理后的 LDPE 薄膜具有明显的时效性,应立即进入下道工序。 |

| Objective To study the change of the surface properties of low-density polyethylene ( LDPE ) film treated by low-temperature plasma. Methods The LDPE film was treated by low-temperature plasma under different treating conditions to compare the surface morphology, surface contact angle and peel strength of the LDPE film before and after treatment . Results Treating LDPE film using air as treatment atmosphere with 44 W, 30 s, 60 Pa parameters decreased its static contact angle from 101 o to 13 . 5 o . The contact angle of LDPE film quickly rose to 74 o within one hour after low-temperature plasma treatment and lost the plasma treatment effect . Conclusion The air was a better treatment atmosphere than N2 and CO2 . The timeliness of plasma treated LDPE film was obvious and should enter the next process immediately after low-temperature plasma treatment . |
