Abstract
A manufacturing method of a PTC (Positive Temperature Coefficient) element includes: producing a polymer aqueous emulsion solution; producing a polymer aqueous emulsion conductive composite by mixing the polymer aqueous emulsion solution with a conductive agent; and producing the PTC element by coating a substrate with the polymer aqueous emulsion conductive composite, or print the polymer aqueous emulsion conductive composite on the substrate, or dipping the substrate in the polymer aqueous emulsion conductive composite and drying the substrate. Here, the polymer aqueous emulsion solution includes an adhesive polymer, a cross-linking agent, an initiator, and water. The substrate is film, non-woven, textile, inflexible plate, and the like, which are formed of polymer resin.
