Repeat Unit
–[C₄H₂NH]ₙ–
The repeating unit is the smallest structural fragment whose repetition builds the whole chain. Subscripts show the relative share of each unit in copolymers.
Key Properties
Easily electropolymerised directly onto electrodes; good biocompatibility and stability in air; insoluble and infusible once formed.
Applications
Biosensors, neural interfaces, artificial muscles, antistatic coatings.
