Market Need
Polymer surface characteristic control has wide-ranging benefits, especially in applications derived from biocidal and/or amphiphilic behavior. To alter surface properties, some methods, such as chemical modification, plasma, and grafting, require post-processing of bulk polymers. A preferred technique is to modify bulk polymers with additives that migrate to the surface where their properties prevail while the bulk polymer remains otherwise unchanged. Efficiency is gained by reducing process steps and minimizing the amount of modifier added. Polymeric surface modifying additives are therefore highly desirable for their combination of manufacturing efficiency and surface property control.
Technology Summary
These are novel polymeric surface modifiers (PSMs) that control bulk polymer surface biocidal and wetting activity and incorporation of dyes, sensors, and adhesives. The biocidal activity is achieved without biocide release. Wetting behavior includes both anticipated amphiphilic response and, more significantly, a contraphilic response where surfaces are hydrophobic from water contact and hydrophilic from organic solvent contact. The method for producing these PSMs can be easily scaled-up. The PSMs could be incorporated into a variety of materials, including in surgical gloves, medical and biomedical equipment, polyurethane and other plastic products, bathroom and kitchen equipment, protective coatings for wallpaper and countertops, and exercise equipment.
