The Current-Voltage Properties of Ch/AgNP Composite Membranes: A Study on the Effect of AgNP Content

IOP Conference Series: Materials Science and Engineering, 2019
In this study, we report the properties of current-voltage (I-V) of Ch/AgNP (chitosan/silver nanoparticles) composite membranes with emphasis on the effect of the content of AgNP. Composite membranes were made by a casting method using chitosan as matrix, 1% acetic acid as solvent and AgNP as filler. The content of AgNP added was 10, 100, 250, 500, 750
