The employed poly(styrene sulfonate-b-tert-butylstyrene) diblock copolymer (SPS-b-PtBS) possesses two blocks of distinctively different polarity and charge, the hydrophilic SPS which is sensitive to polar substances and the hydrophobic PtBS which is sensitive to organic solvents. The coexistence of two different blocks allows for the detection of a wide variety of agents, ranging from ammonia, and organic solvents, to biomolecules like lysozyme, at room temperature as opposed to alternative usually more complicated techniques, all with the sole use of one sensing medium. Copolymers' high glass transition temperature enables the formation of stable and environmentally robust overlayers. The sensing performance of the material is evaluated experimentally on the customizable platform of polymer optical fibers, demonstrating fast response, high operational reversibility and also reusability in successively different testing agents. 16 pp. LOMv1.0 creator LOMv1.0subject matter expert LOMv1.0 publisher LOMv1.0 Project Final Beneficiary LOMv1.0 Project Executing Organisation 2013 Digital Library of the Operational Programme "Education and Lifelong Learning" abstract types Text Block copolymer Polymeric materials Sensors Biosensors Photonics 1288789 application/pdf http://repository.edulll.gr/edulll/bitstream/10795/1577/2/1577_J%20Polym%20Sci%20Part%20B%20Polym%20Phys%202014%2046.pdf URI http://hdl.handle.net/10795/1577 LOMv1.0creator 2016-01-22T11:58:28Z LOMv1.0validator 2016-01-22T11:58:28Z LOMv1.0 gre no no Copyright EYD-EPEDBM (Operational Programme "Education and Lifelong Learning")
