Project description

The objective of the present project is to develop structural composite materials  with superhydrophobic properties, for antifouling and antifogging function of high voltage outdoor insulation applications. This will reduce the leakage currents, as well as increase the flash over voltages during the lifetime of the outdoor insulation system. The projects contains a new approach for solving this challenging problem by combining two known technologies: patterned functional surfaces and regenerative superhydrophobic surfaces. The polymer composites will contain micro- and nanofillers, protected by a superhydrophobic structure. The adhesion of pollution particles and moisture to these functional materials will be investigated during various conditions, as well as time scales. The relation between these properties to leakage current levels and flash over voltages will be investigated. The investigated concept is primarily intended for HV/MV composite outdoor insulation, but the use as a structural coating on ceramic insulation can also be considered.
