Abstract
본 연구에서는 용매변색성을 지니는 폴리다이아세틸렌(polydiacetylene, PDA)을 중합하여 이를 함유한 폴리다이메틸실록산(polydimethylsiloxane, PDMS) 기반의 필름센서를 개발하였으며 이를 이용하여 클로로포름에서의 용매변색을 확인하였다. 다이아세틸렌(diacetylene, DA) 단량체인 2-methoxyethyl pentacosa-10,12-diynoate(PCDA-EGME) 를 합성하고 저온에서 254 nm UV를 조사하여 PDA를 광 중합한 후, 이를 PDMS에 내포시켜 필름 센서를 제조하였다. 필름형 센서는 적색(λ max=545 nm)을 띠고 있으며, 센서를 클로로포름에 노출시키면 황색(λ max=477 nm)으로 변하는 것을 관찰하였다. 총 19 종의 용매 중 클로로포름에서 선택적으로 변색이 발생하였으며 이를 이미지 분석을통해 CMYK 중 yellow, magenta 값을 추출하여 차이 값을 분석하였다.
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.
