Noticeably, the resistivity of PVOH-coated sample is lower than 2wt
%, 5wt% and 9wt% GNP added PVOH coating, indicating that PVOH
treatment alone would result in acceptable resistivity in all humidity
level for ESD protective packaging. Both PVOH and water
have hydrogen bonds, in which anions cannot move freely due to
the strong hydrogen bonds. However, the protons can move along
these hydrogen bonds acting as proton conductor
