Abstract: |
The surface of low density polyethylene (LDPE) was modified using low temperature O2 plasma technology under the condition of working pressure of 20Pa and treatment power of 30W. The results have been analyzed with contact angle measurement, Fourier transformed infrared spectroscopy (FTIR), atomic force microscopy(AFM),differential scanning calorimetry (DSC),etc.. The results showed that the contact angle was gradually decreased in the 0～20s treatment time and theirs values did not cause significant changes during the 40s～300s treatment time; the contact angle was gradually increased with the place time; the surface of LDPE could form some polar species such as carbonyl, hydroxyl and carboxyl groups and the thermal behaviors of the surface (mainly crystallinity) were changed after treatment by low temperature O2 plasma.
