Abstract

Systems, methods, and compositions for producing liquid repellant materials include a first support configured to support a spool of flexible substrate, a second support configured to support a plurality of compressing rollers configured to apply a force to a segment of the flexible substrate that extends from the roll. The segment is located within a zone between the compressing rollers. The system, in an embodiment, has a plurality of gas directors, wherein each one of the gas directors is configured to direct a stream of gas that flows at least partially around one of the compressing rollers. The streams cause an air pressure reduction in the zone. Also, the system has a precursor supply configured to expose the substrate to a precursor (e.g., a siloxane precursor), resulting in a coated material or protected material.

Abstract

Systems for producing coated textiles using photo-initiated chemical vapor deposition is presented. The system includes a process chamber and a light source of ultraviolet light. The process chamber includes a transparent window, a substrate stage disposed below the transparent window and a plurality of ports. The ports include a first inlet port and a second inlet port. The first inlet port transports a vapor-phase monomer into the process chamber and the second inlet port transports a vapor-phase initiator into the process chamber. The process chamber is controlled to deposit the monomer and the initiator onto a textile substrate. The light source of ultraviolet light is positioned to introduce the ultraviolet light into the process chamber via the transparent window. The ultraviolet light polymerizes the monomer and the initiator to coat the substrate with a polymer.
