I am about to make a TENG with Polycaprolactone (PCL), the only problem that I am not sure about is if this material is very positive, like Nylon 66, cotton.. or very negative like PVDF, PDMS... Can someone help me with that? Thank you.
Polycaprolactone is a biodegradable polyester with a low melting point of around 60 °C and a glass transition temperature of about −60 °C. Polycaprolactones impart good resistance to water, oil, solvent and chlorine to the polyurethane produced. No charge at surface.
