Change in the Contact and Adhesion Properties of Plasma-Modified Polyketone Films Stored under Different Conditions

The effect of storage under different conditions on contact and adhesion characteristics was studied for plasma modified films from commercial aliphatic polyketone Poketon™. The films were stored at room temperature and normal pressure in a humidity chamber and after isothermal heating. The change in the wettability, surface energy, and its polar and dispersion components was studied. Data on the retention of these parameters under different storage conditions were obtained, and the change in adhesion properties (peel strength) was estimated by using Scotch®810 adhesive tape.
