| Abstract: |
| 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 . |
