Colorimetric sensors for volatile organic compounds (VOCs) based on conjugated polymer-embedded electrospun fibers

A colorimetric sensor system for volatile organic compounds (VOCs) has been developed. By using polydiacetylene-encapsulated electrospun fiber mats, common organic solvents, such as chloroform, tetrahydrofuran (THF), ethyl acetate (EA), and hexane can be differentially detected on the basis of color patterns that are produced.
