PREPARATION OF AMPHIPHILIC MEMBRANES USING PHOTOSENSITIVE POLYMERS AND THEIR APPLICATIONS ON THE ENZYME ELECTRODE

To decrease the mass transfer resistance of oxygen permeation and to improve the response of the enzyme electrode, a series of hydrophilic-hydrophobic polyvinylcinnamate (PVCin) membranes were developed. The PVCins were synthesized from polyvinyl alcohol using various amounts of cinnamoyl chlorides in the presence of alkali. The amphiphilic membranes were prepared by using photosensitive PVCin and/or sensitizers that were used instead of the traditional Teflon-hydrophilic two-layer membranes. The properties of photocrosslinking, water and oxygen permeability of the amphiphilic membranes, the calibration curves, and the characteristics of the enzyme electrode prepared by the amphiphilic membranes were investigated.
