Hydrophobic properties of poly(arylene ether)s derived from linear polydimethysiloxanes and decafluorobiphenyl

Abstract

A series of novel poly(arylene ether)s were synthesized with diphenol liner polydimethysiloxanes with different silicon numbers (2OH-PDMS-P; P 5 2, 6, 10, 12, 16) and decafluorobiphenyl via a two-step nucleophilic substitution polymerization. The chemical structures of the polymers were confirmed by Fourier transform infrared spectrometer, 19 F-NMR and 1 H-NMR spectra. All the polymers provided outstanding hydrophobic properties, high thermal stability and good solubility. The water contact angle (WCA) first increased and then suddenly decreased with the increasing of silicon numbers in PDMS. The highest WCA about 1128 was obtained when silicon numbers was ten.

Non‐hermetic packaging of biomedical microsystems from a materials perspective: A review

“…Flexible polymeric materials, such as thermoplastic polyurethanes (TPUs) (Bergmeister et al, 2015), polyimide (Palopoli‐Trojani et al, 2016; Rubehn & Stieglitz, 2010; Woods et al, 2018), parylene (Agarwal et al, 2018; Chang et al, 2013; Lecomte et al, 2017; Rodger et al, 2006; Shapero et al, 2016), polydimethylsiloxane (PDMS; Lachhman et al, 2012; Wang et al, 2015; Aceros, Yin, et al, 2012; Ko, Wang, & Lachhman, 2015; Brancato, Weydts, Oosterlinck, Herijgers, & Puers, 2017; Chong, Lou, Bogie, Zorman, & Majerus, 2019; Guo et al, 2013; Kim, Lee, et al, 2012; Lee & Cho, 2005; Lin et al, 2018; Majerus et al, 2018; Majerus, Dunning, Potkay, & Bogie, 2017) and liquid crystal polymer (LCP) (Lee et al, 2011), (Chen et al, 2006; Dean, Pack, Sanders, & Reiner, 2005; Jeong et al, 2015; Park, Jeong, Moon, Kim, & Kim, 2016; Schuettler & Stieglitz, 2013), have many properties that are attractive for non‐hermetic packaging. Table 1 offers a summary of these properties.…”
