title = "Smart coatings: Core-shell particles containing poly(n-butyl acrylate) cores and chitosan shells as a novel durable antibacterial finish",
abstract = "A novel antibacterial coating for cotton fabrics has been developed using core-shell particles that consist of poly(n-butyl acrylate) (PBA) cores and chitosan shells. The spherical particles were prepared via a surfactant-free emulsion copolymerization of n-butyl acrylate in an aqueous chitosan solution. The particles had a narrow particle size distribution with average diameter of approximately 300 nm, and displayed highly positive surface charges. Transmission electron microscopic (TEM) images clearly showed well-defined core-shell morphology with PBA cores and chitosan shells. Cotton fabric was coated with PBA-Chitosan particles through a conventional pad-dry-cure process without using any chemical binders. Fabric antibacterial efficiency was evaluated quantitatively against Staphylococcus aureus by using the shake-flask method. The results showed that particle-coated fabric had an excellent antibacterial property with bacterial reduction more than 99 %. The durability of the antibacterial property was maintained above 90 % bacterial reduction even after 50 times of home laundering. Effects of particles coating on fabric hand, air permeability, break tensile strength and elongation, as well as fabric surface morphology, were investigated.",
