Poly3-(4-AIkoxyphenyl)thiophenes Based Chemical Sensors

摘要

Polythiophenes and, in particular, poly(3-alkylthiophenes) have attracted much interest as VOCs sensing materials due to their good environmental stability, easy processability and their particular sensing ability. In this work, the potentiality of a particular class of polythiophenes, the highly regioregular poly [3-(4-alkoxyphenyl)thiophenes], has been investigated as VOCs sensor. This class of polymers showed long term stability under room temperature operation, very high sensitivity towards hydrocarbons and low response time.
