| 摘要 |
The present invention provides numerous embodiments of new surface treatment methods, their apparatus for carrying out those methods, and articles made thereby. Numerous embodiments are disclosed which provide for a novel surface treatment for substrates to provide various properties, including but not limited to wettability, electrical conductivity, , improved adhesion, metallizability, sanitization, lubricity, abrasion resistance, static resistance, thrombo-resistance, anti-microbial, paintability, strengthening, vapor barrier properties, reflectivity, and voidless coverage of the treated article. The surface treatment is effected by subjecting a substrate, whether it is a polymeric sheet, some powder, a foam sheet, yam, or a fabric, to at least a sulfur containing gas for a relatively short period of time to provide a sulfonated surface treatment. Additional gases may be reactive or non- reactive in partial pressures effective within the range of the sulfur containing gas.
