Processes for preparing barrier layer films for use in enzyme electrodes and films made thereby |
摘要 |
Methods for forming thin layer barrier layer films for use in enzyme containing laminated membranes and membranes formed thereby are disclosed. The barrier layers exhibit improved acetaminophen rejection and comprise a cellulose acetate/cellulose acetate butyrate blend. The thin layer barrier membranes are formed from a plural solvent containing solution and are cured at a critical temperature of about 102 DEG -114 DEG F., most preferably at about 106 DEG F.-114 DEG F. while traveling through a circulating hot air oven. Alternatively, the membranes can be cured at room temperature or in a stagnant oven at temperatures of from room temperature to about 175 DEG C. (350 DEG F.) for a period of from about 10 minutes to 1 hour.
