폴리다이아세틸렌-폴리다이메틸실록산 기반의 클로로포름 검출센서

초록

In this study, we have developed a solvatochromic polydiacetylene(PDA)-embedded polydimethylsiloxane (PDMS) film-type sensor for selective colorimetric detection of chloroform. PDA-PDMS film was readily fabricated by mixing PDA which was derived from 2-methoxyethyl pentacosa-10,12-diynoate (PCDA-EGME) and PDMS precursor. The PDA embedded PDMS film displayed a red (lambda(max)=545 nm) to yellow (lambda(max)=477 nm) colorimetric transition upon exposure to chloroform. The film-type sensor was found to be selective for chloroform among 19 common solvents.
