Özet
Polyimide (PI) and polyimide-boron nitride (PI-BN) composites as dopamine-selective membrane were synthesized. The structures of the monomer, pure PI, and PI-BN composites were characterized by FT-IR, SEM, and thermal analysis techniques. Experiment results showed that introduction of BN particles increased porosity, selectivity and improved heat-resistance of polyimide matrix. Selectivity of PI-BN composite membranes toward dopamine and interferences was examined by DPV technique. Electrochemical measurement results illustrated that polyimide membrane containing 5% BN possessed wide linear ranges, excellent sensitivity, selectivity, reversibility, and low detection limits (4 X 10(-8) M). The polyimide membrane was very high R value (0.9904). [GRAPHICS] .
