Treating polyvinyl chloride material with plasma, and the contact angle and shear strength, then study the changes of wettability and surface cohesiveness of the polyvinyl chloride material after modification. Measuring the background mass spectrometry and the mass spectrum of the intermediate product in the treatment of PVC, then we investigated the changes in gas composition during plasma treatment of PVC. Based on the analysis of contact angle and we found that the contact angle of PVC treated by plasma changed and the surface wettability was obviously improved. We also found that the shear strength of PVC treated by plasma showed a significant increase in surface bonding performance. The analysis of mass spectrometry shown that the composition of the air after plasma treatment of PVC changed a lot.
