Structure of polymer solutions containing fumed silica.
Small angle neutron scattering is employed to estimate the interactions in complex multicomponent systems. The method is applied to describe a ternary system, poly(dimethyl siloxane) toluene with silica filler particles. Contrast variation by solvent deuteration is used to distinguish the three different partial structure factors of filled polymer samples, S(pp)(q), S(pf)(q), and S(ff)(q), wher...
متن کاملInvestigation of Fumed Silica/Aqueous NaCl Superdielectric Material
A constant current charge/discharge protocol which showed fumed silica filled to the point of incipient wetness with aqueous NaCl solution to have dielectric constants >10⁸ over the full range of dielectric thicknesses of 0.38-3.9 mm and discharge times of 0.25->100 s was studied, making this material another example of a superdielectric. The dielectric constant was impacted by both frequency a...
متن کاملStabilizing bijels using a mixture of fumed silica nanoparticles.
Bijels are typically prepared by arresting the phase separation of two liquids using interfacial particles. The surface treatment of the particles is challenging but can be overcome at a cost (Cui et al., Science, 2013, 342, 460-463). Here, we use mixed commercial fumed-silica nanoparticles, giving a facile route to bijel production.
متن کاملRheological study on the aging process in a polymeric fumed silica suspension
Understanding the influence of storage time on the rheological properties polymeric fumed silica gels is very important in the field of composite polymer electrolytes. A rheological study of the aging process of Aerosil R805 suspension in Polypropylene Glycol Mw2000 has been carried out by means of steady and oscillatory experiments.
متن کاملEffects of Fumed and Mesoporous Silica Nanoparticles on the Properties of Sylgard 184 Polydimethylsiloxane
The effects of silica nanoparticles on the properties of a commonly used Sylgard 184 polydimethylsiloxane (PDMS) in microfluidics were systemically studied. Two kinds of silica nanoparticles, A380 fumed silica nanoparticles and MCM-41 mesoporous silica nanoparticles, were individually doped into PDMS, and the properties of PDMS with these two different silica nanoparticles were separately teste...
