METHODS, SYSTEMS, AND POLYMER SUBSTANCES RELATING TO CONSIDERATION OF H2O LEVELS PRESENT WITHIN AN ATMOSPHERIC-PRESSURE NITROGEN DIELECTRIC-BARRIER DISCHARGE.

摘要

Methods and systems utilize an atmospheric-pressure nitrogen dielectric-barrier dischargeto treat the surface of polymer substances. The atmospheric-pressure nitrogendielectric-discharge may be maintained with a level of H2O below apre-defined amount, such as by measuring and controlling the H2O withina treater, to produce a surface treatment for a polymer substance that yieldsdesirable characteristics. Furthermore, the H H2O level may be measuredand controlled according to a pre-defined amount or according to another parametersuch as an analysis of the resulting polymer surface. For example, the polymersurface may be provided with an optimal added nitrogen-to-added oxygen ratioand/or an optimal stability based on washed and unwashed advancing contact anglessuch as by controlling the H2O level within the treater based on theseanalyses of the treated polymer.
