Determination of optimal plasma treatment time of polypropylene

Plasma treatment is one of the most used surface treatment method to improve adhesion of the materials. Plasma treatment is especially used to treat polymer surfaces as polymers typically have very low surface free energy.plasma treatment of PP This leads to adhesion failures when coatings are applied. 

In this case study we will show: 

  • How contact angle measurements should be conducted 
  • How surface free energy can be utilized to determine the optimum plasma treatment time
