Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iodine-supported materials on activated carbon can scatter in the air or disperse in water, impairing their bactericidal power, necessitating a method to directly impart antibacterial and deodorant functions to materials like fibers, fabrics, and plastics without using activated carbon.
Innovation Solution
Reacting iodic acid with materials such as calcium silicate or gypsum to produce water-insoluble iodate compounds on their surfaces, which are non-toxic and maintain antibacterial and deodorant effects without elution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If iodine is supported on activated carbon powder, then antibacterial and deodorant functions are achieved, but the activated carbon scatters in air or disperses in water, impairing the bactericidal power
Solution Approach 1:
The invention extracts the problematic activated carbon supporter and replaces it with stable inorganic materials (calcium silicate, limestone, diatom earth, gypsum, or plastic) that do not scatter or disperse. The iodine is directly supported on these stable materials, eliminating the scattering issue while maintaining antibacterial function.
Solution Approach 2:
The invention changes the physical and chemical parameters of the supporter material from organic activated carbon to inorganic materials with different properties (water insolubility, air stability). This parameter change resolves the scattering problem while preserving the iodine's antibacterial effectiveness.
2Power
If iodic acid is used to impart antibacterial function, then strong oxidizing power is achieved, but the iodate ion diffuses in water and bactericidal power is impaired
Solution Approach 1:
The invention creates a composite structure where iodate is combined with water-insoluble inorganic materials (calcium silicate, limestone, etc.). This composite approach allows the iodate to maintain its oxidizing power while the insoluble matrix prevents diffusion and loss of bactericidal activity in water.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method allows for direct impartation of antibacterial, antiviral, fungicide, and deodorant properties to materials like textiles, plastics, and building materials, ensuring long-lasting effectiveness without the risks of scattering or water solubility impairing the iodine's disinfecting power.
Implementation Method 1
processing to react iodate compound to a material that includes an element capable of producing water-insoluble iodate
Implementation Method 2
producing iodate of such element on the surface of such material to make the iodate to be supported enabling to do antibacterial and deodorant effects without elution of the iodate to the outside
Implementation Method 3
Iodic acid dissolves in water to generate iodate ion (IO3−), but its bactericidal power is impaired if it is diffused in water
Implementation Method 4
its bactericidal power is impaired if it is diffused in water
Implementation Method 5
an iodine-supporting material in which elemental iodine is supported on a material such as activated carbon

AI summary
Provided is a method of imparting antibacterial and deodorant functions by reacting iodic acid, and a material that is given antibacterial and deodorant functions. The method of imparting antibacterial and deodorant function is as follows. Reacting iodate to a material that includes elements capable of producing iodate insoluble in water and non-toxic to a living body to form iodic acid of such elements on the surface of the material, thereby the iodate is made to be supported so that antibacterial and deodorant is possible without elution of said iodate to the outside.
