Adsorption of particles on a material containing a silicone polymer
A device for the dry cleansing of surfaces to remove particulates contains triboelectrically chargeable component(s) of an organic polymer material containing uniformly distributed finely divided silicone polymer particles.
1. A method for adsorption of particles by triboelectric charging, comprising adsorbing the particles on a material M which comprises an organic polymer material with silicone polymer(s) finely distributed therein, wherein the content of the silicone polymer in the material M is at least 0.0001 wt. % and less than 10 wt. % and wherein said silicon polymer comprises UHMW polysiloxane (ultra-high molecular weight silicone) having a dynamic viscosity from 1 kPa·s to 50 kPa·s at 25° C.
2. The method of claim 1 , wherein the organic polymer material is an organic plastic.
3. The method of claim 1 , wherein the organic polymer material is selected from the group consisting of polyolefin, polyester, polyamide, polyimide, polyamide imide, polyphenylene sulfide, aramide, polyacrylonitrile, polyacrylonitrile polymethacrylate copolymer, polyacrylonitrile polyvinyl chloride copolymer, polyvinyl chloride, polytetrafluoroethylene and polyurethane.
4. The method of claim 1 , wherein the UHMW polysiloxane is a linear polydiorganosiloxane.
5. The method of claim 1 , wherein the UHMW polysiloxane has an average particle size of less than 10 μm.
