Surface membrane structure with negative ion antibacterial layer

Abstract

This invention relates to a surface membrane structure with a negative ion antibacterial layer, comprising a plastic base body and a surface plastic negative ion antibacterial layer. The plastic base body and the surface plastic negative ion antibacterial layer are made of the same plastic material. The surface plastic negative ion antibacterial layer is solidified and bonded to the plastic base body. The thickness of the surface plastic negative ion antibacterial layer is the same as, or greater than or less than, 1 / 2 the thickness of the plastic base body. This allows the negative oxygen ion emission and antibacterial properties of the surface plastic negative ion antibacterial layer to be continuous and stable, achieving the effects of long-lasting negative oxygen ion emission and excellent antibacterial effect.
