The invention discloses a novel polymer positive temperature coefficient (PPTC) material, device, and method of fabrication. One example of polymer positive temperature coefficient (PPTC) includes a polymer matrix, the polymer matrix comprising a first polymer. The PPTC material may further include a conductive filler, disposed in the polymer matrix; and at least one polymer filler, dispersed within the polymer matrix. The at least one polymer filler may comprise a second polymer, different from the first polymer, wherein the at least one polymer comprises a first melting temperature, and wherein the second polymer comprises a second melting temperature, the second melting temperature exceeding the first melting temperature by at least 20 DEG C. 一种新颖的聚合物正温度系数(polymer positive temperature coefficient,PPTC)材料、装置、及制造方法。聚合物正温度系数(PPTC)的一实施例包括聚合物基质，该聚合物基质包含第一聚合物。该PPTC材料可进一步包括导电填料，该导电填料设置于该聚合物基质中；及至少一种聚合物填料，该至少一种聚合物填料分散于该聚合物基质内。该至少一种聚合物填料可包含第二聚合物，该第二聚合物不同于该第一聚合物，其中该至少一聚合物包含第一熔融温度，且其中该第二聚合物包含第二熔融温度，该第二熔融温度超过该第一熔融温度至少
