Opis ogólny
Polyurethanes are a broad class of polymers which have urethane group (-NHCO-O-). Urethane group is formed by isocyanate reacting with hydroxyl groups.

Zastosowanie
Polymeric membrane material for chemosensors and biosensors
Polyurethane was used as an outer coating membrane to increase stability and the linear range of the sensor during development of glutamate microbiosensor. It may also be suitable in investigating the thermal degradation of α,γ-diphenyl alkyl allophanates and carbanilates for crosslinking sites using pyrolysis-high-resolution gas chromatography/FT-IR (Py-HRGC/FT-IR).
Inne uwagi
Membrane material with favourable properties for sensors, e.g. long-term electrochemical stability, improved biocompatibility, etc.

Potentiometric responses of polyurethane (PU)-based membranes containing valinomycin and varying amounts of plasticizer (DOA) and/or lipophilic additive (KTpClPB) were examined as a function of soft segment [poly(tetramethylene ether glycol)] contents in aromatic diisocyanate-based PU matrices. Upon increasing the weight percentages
