Abstract: Highly porous nucleophilic organic cages (Nu-POC) were in-situ synthesized on cotton fibers by a condensation reaction between cyanuric chloride and melamine, and the products were employed as a robust wearable and flexible detoxifying protective material (denoted as POCotton) for vaporous pesticides. The covalent growth of Nu-POC particles on surfaces of cotton fibers retained the physical characteristics of Nu-POC to the greatest extend, which include specific surface area and porosity, while the cotton fabrics still remained wearable. The resultant POCotton can repeatedly adsorb fumigant vapors instantly (i.e., equilibrium reached within one minute) and massively (i.e., adsorption capacity at 596.88 mg/g of methyl iodide).

Abstract: Disclosure provides antimicrobial fiber, comprising: a cationic or polycationic moiety grafted onto a cellulosic fiber and an anionic photosensitizer. Exposing the antimicrobial cotton fiber to light generates reactive oxygen species (ROS) and induces a biocidal function.
