Structuring of hydroxy-terminated polydimethylsiloxane filled by fumed silica

Effects 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...

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...

Tensile Behaviour and Fracture Characteristics of Polydimethylsiloxane (PDMS) filled Silica Composites

The focus of this study is to investigate the mechanical properties and fracture behaviour of polydimethylsiloxane filled crystalline silica composites (PDMSJCS) via tensile test. The PDMSICS composites were fabricated by using casting method and cured at room temperature for 24 hours. Crystalline silica were filled into PDMS at composition of 2, 6, 10 wt%. The tensile properties of PDMS/2wt%CS...
