ObjectiveConductivity of PVOH films DescriptionMeasure the conductivity of a PVOH film crosslinked with glutaraldehyde (see 9/14/12 for procedure) at different time intervals. Datacell constants: 0.4663 (orion versa star) 0.479 (orion 5 star) The following solutions were used on either side of the film
