Preparation of an injection molding stainless-steel tool and optimization of the processing parameters to fabricate superhydrophobic silicone rubber insulators

This project is defined to mitigate the problems associated with the accumulation of ice and pollution on the high-voltage insulators and subsequent flashover and power outage. Superhydrophobic surfaces, having a controlled combination of low surface energy materials and surface roughness, are one of the best candidates for icephobic and self-cleaning applications. As the high-voltage silicone rubber insulators are manufactured using injection molding systems, this project aims to prepare an industrial injection molding system for fabrication of superhydrophobic insulators. To this end, proper surface features (in micro- and nanometer size) will be created on the injection molding tool. The molding parameters will also be modified to properly replicate the tool’s patterns on the silicone rubber surface. Consequently, the produced silicone rubber insulator, having surface micro-nanofeatures, will acquire superhydrophobic and subsequent icephobic and self-cleaning properties. This project can put the partner organization as the leading enterprises in the field of electrical transmission lines in Canada and worldwide.
