Development of slow release chlorine dioxide antibacterial film

A non-woven fabric as a carrier for the reaction component, a polyvinyl alcohol coated sodium chlorite component A and an acid combination B encapsulated with β-cyclodextrin were separately prepared to prepare a dioxide having a sustained release function. Chlorine antibacterial film. Through experimental verification, the results show that when the structure of the film is to add a certain amount of sodium bromide to the B component, a commercially available cling film with a moisture permeability of 33%±20% is sandwiched between the A and B films. The optimum structure is as follows: when the humidity of the space environment is 85%, the effective release days can reach 17 days, and the effective daily release amount is maintained between 0.15~1.5 mg of effective chlorine dioxide release, which can be used according to the need of antibacterial space. The size of the film is small, it is a new environmentally friendly material that is easy to use, safe and efficient.
