Inorganic nano-antibacterial materials development and application progress in household products
In the background of Health China strategy,household products with healthy benefits,such as antibacterial fibers and antibacterial plastics,have attracted extensive attention because of their excellent antibacterial properties and applicability.Based on physiochemical properties of antibacterial materials,academic researchers and engineers from industries have developed a variety of products.This review summarized the antibacterial mechanisms of inorganic nano-antimicrobials including contact reaction mechanism and photocatalytic antibacterial mechanism,recent advances in nano-metallic species,nano-oxides and other nano-antibacterial materials and composite materials and related applications of inorganic antimicrobial agents,and antimicrobial household products such as antimicrobial textiles,antimicrobial plastics,antimicrobial coatings,antimicrobial ceramics,water and gas filtration and purification.The analysis indicated that inorganic antibacterial materials should be paid great attention to in terms of structure optimization,antibacterial waste recycling and toxicity research,as well as green and sustainable development.In the future development,this review also pointed out potential trends(e.g.development of antibacterial materials with porous structures and multi-points for synergistic function,green synthetic technology in the background of Dual Carbon Policy and easy examination methods for household antibacterial products),some problems for nowadays applications of inorganic nanomaterials(e.g.difficulty in dispersion,compatibility and stability with polymer matrix),and forecastd future market prospects for household antibacterial products.
