Sigma-Aldrich 聚吡咯-嵌段-聚己内酯，0.3-0.7重量%（在硝基甲烷中的分散体），含有对甲苯磺酸盐作为掺杂剂

产品概述

Sheet resistance, spin cast thin films: 10,000-50,000 Ohms/sq

Average 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.

应用领域

Thin films can be prepared by spin casting the nitromethane dispersion at 1000 rpm. To spin coat a thin film at 1000 RPM, 30 seconds to 1 minute is usually enough time to spread this dispersion. Thicker and more conducting films can be prepared by air spraying the dispersion on a substrate. Any substrate that is compatible can be used. 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. The drying time of the air sprayed film depends on the thickness of the prepared film. Try weighing the sample periodically during drying.
