Waterproofing polymer films modified in gliding arc plasma

The article considers the use of polyethylene modified in sliding arc plasma as a waterproofing material. It assesses influence of plasma modification on physical and mechanical properties of polyethylene films by testing for relative elongation and maximum load. The study establishes increase in the size of supramolecular structures in crystalline parts, changing the strength properties of polymer film. It has been experimentally proven that application of 10-second plasma modification by sliding arc using the developed plasma installation results in formation of activated layer on the surface of polyethylene films, which increases the strength characteristics of the material. It has been determined that modifying the polyethylene within 10 seconds increases the strength of the polymer films. Due to increased mechanical strength and changed surface structure, modified polyethylene films are of interest as a base material for creating polymer-roll waterproofing materials.
