TL;DR: Two types of polymer-silica nanocomposites have been prepared by undergoing free radical polymerization of 2-hydroxyethyl methacrylate (HEMA) either in the presence of HEMA-functionalized SiO2 nanoparticles (Type 1) or during the simultaneous in situ growing of the silica phase through the acid-catalyzed sol-gel polymerisation of TEOS (TEOS) as mentioned in this paper.

TL;DR: In this article, the ability of different geometrical models to describe the experimental relative permeability data is discussed, which leads to the conclusion that it is necessary to consider the polydispersity of the impermeable filler shapes and to take into account the presence of surfactant located at the inorganic surface to appropriately model the transport properties of the nanocomposites in a large range of nanoclay contents.

TL;DR: This study demonstrates that the silylation reaction and the interlayer microstructure of the grafting products strongly depend on the original clay materials.

TL;DR: In this paper, the role of asphaltenes in asphalt viscoelastic properties is investigated and it is shown that a temperature dependent solid fraction exists within a liquid (or glassy) matrix.

TL;DR: In this paper, the processing and mechanical properties of new thermoset nanocomposites prepared from aqueous suspensions of microcrystalline cellulose fillers and epoxy are described.
