Title: Innovator Spotlight: Brian D. Blackledge – Pioneering Semiconductive Materials
Introduction: Brian D. Blackledge, an inventive force hailing from Taylorsville, MS, has made significant strides in the field of materials science with his innovative patents. His work primarily focuses on the development of revolutionary semiconductive materials that promise to enhance electrical performance without the need for complicated processing techniques.
Latest Patents: Brian holds two noteworthy patents that showcase his expertise and forward-thinking approach. His latest patent describes a PTC (Positive Temperature Coefficient) composition that incorporates low molecular weight polymer molecules, allowing for a sharp increase in electrical resistance at a predetermined maximum temperature. Notably, this innovative material requires substantially no annealing post-extrusion, achieving an essentially constant resistance at room temperature. The composition features finely divided conductive materials—such as carbon black—and a semicrystalline polymer that contains a sufficient number of relatively low molecular weight molecules. These molecules help to eliminate the necessity of annealing and ensure effective electrical conductivity by integrating a suitable polymeric material with a high number of polar molecules. Specifically, at least 9% by weight of the polymer molecules are in the molecular weight range of 1,000 to 30,000, with particular emphasis on the range of 5,000 to 23,000. Additionally, the overall polymeric portion maintains a number average molecular weight of 30,000 or less, solidifying its innovative potential.
