A novel coating process for particle binding to textile interface for improved antimicrobial performance

P. Cronin*, M. Osiak, Mica NanoTech Ltd, Ireland

Antimicrobial surfaces are considered important in preventing the spread of drug resistant pathogens in both health care and community environments. The incorporation of antimicrobial nanoparticles (NPs) into material surfaces has received significant attention especially in textiles for self-cleaning or self-sterilization applications. The surface of these NPs is chemically active or can become active when exposed to a stimulus e.g. solar radiation. The interface between the NP and the textile fibers must be tailored to optimize the surface area of the NPs for maximum antimicrobial activity while sufficiently anchored into the surface of the textiles so that the bonding between the NPs and the textiles is durable for the intended purpose and do not create health or environmental concerns due to the release of NPs. This study shows a novel binder-free method of achieving such adhesion of NPs to a textile surface. The NP embedding process into textile and the interfacial adhesion mechanism is elaborated using contact mechanics underpinned by experimental verification.
