A recently published article reports the modified surface morphology of Poly-vinyl Alcohol (PVA) films using electro-spraying coating technique.
Atomic force microscopy (AFM) and scanning electron microscopy (SEM) were conducted to examine the surface structure of the prepared PVA films. Intriguingly, the novel micro-level developed surface, twisted by electro-spraying is very promising for humidity sensors.
The resistivity of the humidity sensors was measured under controlled humidity levels. Owing to the unique surface assembly, the electro-sprayed humidity sensor showed superior performance as compared to the electro-spun PVA based humidity sensor.
