The hydrophobic recovery of polydimethylsiloxane elastomers was studied after exposure to partial electrical discharge. Silicone elastomers that were thoroughly extracted of free oligomeric impurities as well as those deliberately contaminated with low molecular weight (LMW) silicone fluids were use

Silicone elastomers exposed to electrical discharges can be rendered hydrophilic, and the loss of water repellency is related to the energy level and number of the discharge pulses on the surface. However, the silicone surface has the unique ability to recover the hydrophobicity and enhance the perf
The thermal expansion coefficient and physical aging behavior of cured epoxy resins modified with amino-terminated polydimethylsiloxane were investigated. The epoxy resin was tetramethyl biphenol diglycidyl ether. Two factors influenced the thermal expansion behavior and the free volume relaxation o
