Product Name

Polypyrrole-block-poly(caprolactone)

Structure

Category

Bioelectronic Materials; Biodegradable Polymers

Synonyms

Biotron PP-NM,PCL-block-PPy

Description

Sheet resistance, spin cast thin films: 10,000-50,000 Ohms/sqAverage transmittance: 70-90%Biodegradble conducting polymer for bomedical applications. PCL diol blocks have average molecular weight 2000 and PPy block have an average molecular weight of 4000 with a 25% doping level. Good biocompatibility with expected weight loss of 40% at 200 days in pH=7 buffer.

Application

Thin films can be prepared by spin casting the nitromethane dispersion at 1000 rpm. Thicker and more conducting films can be prepared by air spraying the dispersion on a substrate. Sprayed films can be dried at 30-40 °C, then pressed between two polished dye plates at 1000-10,000 psi to increase film density, strength and scratch resistance.
