Poly(sulfobetaine methacrylate) was grafted from poly(vinylmethylsiloxane) elastomer substrates using thiol-ene click chemistry and surface-initiated, controlled radical polymerization. These surfaces exhibited both fouling resistance and triggered fouling-release functionality. The zwitterionic polymers exhibited fouling resistance over short-term (∼hours) exposure to bacteria and barnacle cyprids. The biofilms that eventually accumulated over prolonged-exposure (∼days) were easily detached by applying mechanical strain to the elastomer substrate. Such dual-functional surfaces may be useful in developing environmentally and biologically friendly coatings for biofouling management on marine, industrial, and biomedical equipment because they can obviate the use of toxic compounds.}, number={46}, journal={ACS APPLIED MATERIALS & INTERFACES}, author={Shivapooja, Phanindhar and Yu, Qian and Orihuela, Beatriz and Mays, Robin and Rittschof, Daniel and Genzer, Jan and Lopez, Gabriel P.}, year={2015}, month={Nov}, pages={25586–25591} } @article{mays_dickey_genzer_2013, title={Microfluidic channels fabricated from poly(vinylmethylsiloxane) networks that resist swelling by organic solvents}, volume={13}, ISSN={["1473-0189"]}, DOI={10.1039/c3lc50848j}, abstractNote={This paper describes the use of poly(vinylmethylsiloxane) (PVMS) networks for fabricating microfluidic channels that resist swelling in the presence of organic solvents, thus providing a versatile alternative to poly(dimethylsiloxane) (PDMS).

Nanoskiving is a technique to produce nanoscale structures using an ultramicrotome to section thin films of materials (e.g., gold) embedded in polymer. Epoxies are used typically as embedding resins for microtomy. Epoxies, however, do not adhere well to gold or other smooth metallic structures that are used commonly for nanoskiving. Thiol–ene and thiol–epoxy polymers provide improved adhesion to gold due to the thiol functional group. In addition, the thiol–ene polymers can be prepared within minutes using photopolymerization, which allows for rapid prototyping. Two commercial thiol-containing adhesives were evaluated as resins in addition to several formulations of commercially available monomers. The important physical and mechanical properties for microtomy of these unconventional embedding resins were characterized and the properties were compared to commercial epoxy resins. Gold nanowires were fabricated using nanoskiving of gold films embedded in these unconventional resins. These studies show that a 3 : 4 mixture of thiol (pentaerythritol tetra(3-mercaptopropionate)) and ene (triallyl-1,3,5-triazine-2,4,6-trione) works very well as a resin for nanoskiving and provides improved adhesion and reduced preparation time relative to epoxies.}, number={1}, journal={JOURNAL OF MATERIALS CHEMISTRY C}, publisher={Royal Society of Chemistry (RSC)}, author={Mays, Robin L. and Pourhossein, Parisa and Savithri, Dhanalekshmi and Genzer, Jan and Chiechi, Ryan C. and Dickey, Michael D.}, year={2013}, pages={121–130} } @article{zhu_so_mays_desai_barnes_pourdeyhimi_dickey_2013, title={Ultrastretchable Fibers with Metallic Conductivity Using a Liquid Metal Alloy Core}, volume={23}, ISSN={["1616-3028"]}, DOI={10.1002/adfm.201202405}, abstractNote={Abstract}, number={18}, journal={ADVANCED FUNCTIONAL MATERIALS}, publisher={Wiley}, author={Zhu, Shu and So, Ju-Hee and Mays, Robin and Desai, Sharvil and Barnes, William R. and Pourdeyhimi, Behnam and Dickey, Michael D.}, year={2013}, month={May}, pages={2308–2314} }
