“…We have found that a high contact angle hysteresis is characteristic of side chain partially‐fluorinated systems 6,10,23,24. For example, a polyphosphazene with a side‐chain semifluorinated architecture was examined.…”

“…Our studies have included (1) the surface science of α , ω ‐dihydroxy PDMS macromonomers cured with a semifluorinated ethoxysilane crosslinker, (2) platinum‐cured α , ω ‐divinyl PDMS macromonomers, and (3) ethoxysilane‐(sol gel) cured PDMS. Each of these PDMS network materials have different and complex surface properties 10–14…”

Surface‐modified siloxane networks were prepared using the dibutyltin diacetate catalyzed reaction of α,ω‐dihydroxy(polydimethylsiloxane), HO(Me2SiO)nH, with tridecafluoro‐1,1,2,2‐tetrahydrooctyl triethoxysilane, [CF3(CF2)5(CH2)2Si(OC2H5)3, FTEOS]. Surface characterization of these elastomers was carried out using electron spectroscopy for chemical analysis (ESCA) and atomic force microscopy (AFM). Surface phase separation occurs as a function of increasing ratio of FTEOS to HO(Me2SiO)nH. Dynamic contact angle (DCA) analysis with water as the interrogating fluid showed that water contamination affects DCA data in the compositional range 4x–8x, where “x” is the ratio of ethoxy groups from FTEOS to OH groups in HO(Me2SiO)nH. Diffusion of polydimethylsiloxane oil species from the coatings is blocked in compositions of 10x or greater. Chemical stability is also enhanced for 10x and 12x compositions.

“…After immersion in deionized water for 5 weeks, an increase of R a was observed for each coating, particularly for the PCL-based coatings (R a ≥ 2 µm) which can be explained by the possible surface degradation or polymer chains reorganization. For the PDMS elastomer reference, the roughness slightly increased probably due to the surface migration of a siliceous phase formed by the homocondensation of PDES [44][45][46][47].…”

“…Silicone materials based on poly (dimethylsiloxane) (PDMS) and tetraethoxysilane (TEOS) are known very well and they have been in use for many years in industry and medicine. 30,31 Two different methods of modication were developed. The rst one assume chemical incorporation of TMS in total volume of material by mixing it with PDMS and TEOS (about 1% of TMS is sufficient for modication).…”

“…22,27 Moreover, uorophores are mostly blended within the polymer matrix rather than chemically bonded. [22][23][24][25][26]28,32 Thus, it was not possible to create uorescent symbols and inscriptions because of an obstacle with introduction of the CDs at specic location over the material. Therefore, inkjet-printing technique was proposed to overcome this issue.…”
