Dispersion of gold nanoparticles above the poly(methyl methacrylate) surface by the use of fluoroalkyl end-capped oligomeric aggregates

Synthesis and applications of a variety of fluoroalkyl end‐capped oligomers/silica gel polymer hybrids

“…On the other hand, fluoroalkyl end‐capped DMAA and DOBAA homooligomers/SiO 2 polymer hybrids could afford nanometer size‐controlled particles (84–99 nm). This interesting finding would depend upon whether fluoroalkyl end‐capped DMAA and DOBAA oligomers can form the nanometer size‐controlled molecular aggregates in solutions,19 and these fluorinated aggregate cores should interact with TEOS to afford very fine hybrid nanoparticles.…”

Preparation and applications of novel fluoroalkyl end-capped oligomeric nanocomposites

“…17). 106 The modified cast PMMA film treated with these fluorinated oligomer/Au nanocomposites exhibited a similar plasmon absorption at around 540 nm, the same as for the 1,2-dichloroethane solution system (Fig. 18).…”

“…18). 106 XPS (X-ray photoelectron spectroscopy) analyses showed that gold nanoparticles should be well dispersed above the modified PMMA film (film thickness: 196 mm) surface as well as fluorinated DOBAA oligomers. 106 As mentioned before, the shape of fluoroalkyl end-capped oligomeric aggregates is easily exchangeable under a variety of conditions (see Fig.…”

Color-changing behavior of fluoroalkyl end-capped 2-methacryloyloxyethanesulfonic acid oligomer/polyaniline nanocomposites, triggered by a variety of basic compounds

“…We have hitherto comprehensively studied on the preparation and applications of fluoroalkylated polymers, especially, ABA triblock-type fluoroalkyl end-capped oligomers [R F -(M) n -R F : R F = fluoroalkyl groups, M=radical polymerizable monomer], and these fluorinated oligomers can exhibit a wide variety of unique properties such as high solubility, surface-active property, and nanometer size-controlled molecular aggregates, which cannot be achieved by the corresponding non-fluorinated and randomly fluoroalkylated ones [33][34][35][36][37]. The self-assembled fluorinated oligomeric aggregates formed by these fluoroalkyl end-capped oligomers can provide suitable host moieties to interact with numerous guest molecules such as fullerene, carbon nanotubes, gold, silver and copper nanoparticles, and organic dyes, affording the corresponding fluorinated aggregates/guest molecules nanocomposites [38][39][40][41][42][43][44][45][46][47]. In addition, preparation of poly(vinylidene fluoride) copolymers/silica nanocomposites has been reported including their unique properties [48][49][50].…”
