The Micro-meter-sized plastic texture made by PVC with carbon black and AC electric field to enhance thermal conductivity

抄録

In this study, we created a microplastic texture by a mixture of PVC (polyvinyl chloride)-acetone and carbon black (CB) solution at an alternative high voltage. The results showed that the contact angle when high voltage of 2 kV was applied was greater than that when no voltage was applied, and the surface contact angle showed a maximum of 142° when the CB concentration was 1.5 wt.% and the applied frequency was 0 Hz, while the surface head convex structure was found when the CB was 1.5 wt.% at 10 Hz when observed by field emission scanning electron microscopy (FE-SEM). And it was found that the surface spherical structure was sharper when the frequency was applied at 10 Hz than 5 Hz.
