FIELD: process engineering.
SUBSTANCE: invention relates to modification of polymer material surface. Control over polymer surface modification in low-temperature HV discharge plasma at lower pressures of the medium is performed by varying the discharge power. Here, discharge power is continuously measured, its current magnitude being used for calculation in real time of temperature field in discharge area. Modification termination time is defined automatically when polymer surface reaches the preset temperature (70°C for polyethylene).
EFFECT: reproducibility of the surface adhesive properties, i.e. interfacial angle and work of adhesion, as well as stable surface hydrophysics.
