POSS based ionic liquid as an electrolyte for hybrid electrochromic devices

Ionically conducting Er3+-doped DNA-based biomembranes for electrochromic devices

“…R b is obtained by interception of the imaginary part of the impedance (minimum value of Z") with the slanted line in the real part of the impedance (Z'). It is possible to observe that electrolytes exhibit ionic conductivity results similar to those of comparable materials based on PEO [26,28] and one order of magnitude higher than those based on d-U(600) [27,29]. The most conducting sample, DNA 10 Er, exhibits an ionic conductivity equal to 1.17 × 10 −5 S.cm −1 at 30 • C and 7.76 × 10 −4 S.cm −1 at 100 • C. If practical applications in electrochemical devices are envisaged, high ionic conductivity (higher than 10 −5 S.cm −1 [28,30]), is definitely one of the most important requirements that need to be fulfilled.…”

Highly untangled multiwalled carbon nanotube@polyhedral oligomeric silsesquioxane ionic hybrids: Synthesis, characterization and nonlinear optical properties

“…To this aim, chloropropylisobutyl POSS â was treated with sodium iodide to gain iodopropylhepta(isobutyl)POSS (POSS-I) [35]. Then, mono-imi-POSS/I has been obtained as a white solid in high yield, via alkylation of 1-vinylimidazole by POSS-I [40]. Finally, free radical polymerization of monoimi-POSS/I with AIBN, as described in the Experimental, has led to the wished polymer, poly-imi-POSS/I, which appears as a white solid readily soluble in low and medium polarity solvents (i.e.…”

Bacteriostatic photocatalytic properties of cotton modified with TiO2 and TiO2/aminopropyltriethoxysilane

“…The sol-gel TiP/APTES hybrid finishes resemble aminofunctionalized polymeric systems in many aspects. Namely, TiP/APTES hybrids belong to a class of organic-inorganic hybrid materials that have been extensively studied in our laboratory in the past (Vince et al 2006;Fir et al 2007;Jerman et al 2008;Vilčnik et al 2009;Koželj et al 2009;Č olović et al 2011;Jerman et al 2012;Simončič et al 2014;Vasiljević et al 2014). In the TiP/APTES hybrids studied here, the TiP and APTES acted as sol-gel network formers, while the amino groups of the APTES (the organic part of the hybrid) imparted the hybrid with bactericidal properties.…”
