Abstract(#br)This study explored a click method of using filter paper (FP) and a polydimethylsiloxane (PDMS) polymer coating solution to prepare a cost-effective volatile organic compound (VOC) preconcentrating sampler. This is the first report of successfully cross-linking a hydrophobic polymer with cellulose in filter paper via a sol-gel method and its application to the preconcentration of headspace VOCs.
