liquid crystal, colloid, SAXS Suspensions of three different clays in K15, a thermotropic liquid crystal have been studied by optical microscopy and small angle X-ray scattering. The three clays were Claytone AF, a surface treated natural montmorillonite, Laponite RD, a synthetic hectorite and mined Sepiolite. The Claytone and Laponite were sterically stabilized whereas Sepiolite formed a relat...

It has been brought to our attention that Laponite® is a trademark of BYK Additives, however the trademark symbol is missing in [1].[...].

Stretchable ionic thermoelectric (i-TE) materials have attracted growing interest in converting low-grade thermal energy into electricity. However, substantial improvement on i-TE performance of quasi-solid ionogels remains a significant challenge. Here, nanocomposite ionogel with skin-like stretchability, high performance, thermostability and durability is prepared by hybridizing liquid (IL) L...

Cellulose nanocrystals (CNCs) are attractive substances with interesting colloidal self-assembly behavior and rheological properties due to their rigid rod morphology. In this paper, the aqueous dispersion characteristics as well rheological, optical, structural of binary mixtures CNCs Laponite (L) investigated in detail. We obtain various complex structures by using Laponite. A phase diagram c...

Highly processable hydrogels loaded with active components for localised drug delivery and/or live cells regenerative medicine are an attractive target biotechnology research. We describe a single-pot precipitation polymerisation of poly (N-isopropylacrylamide) (pNIPAM) from the surface dispersed Laponite® platelets in aqueous media above its lower critical solution temperature (LCST), yielding...

Polymer-nanoclay composite materials have attracted considerable interest among materials scientists recently because of the pioneering work carried out by a research group in the Toyota Central Research Laboratories. The group applied a nylon-montmorillonite clay nanocomposite as an under-the-hood structural part in the engine compartment of an automobile with significantly improved tensile st...

a copolymer of styrene and methyl styrene was synthesized by nitroxide - mediated “living” free radical polymerization )nmp). n-bromosuccinimide was used as a brominating agent to obtain a copolymer with bromine as its end group. this brominated copolymer was used as macro initiators for atom transfer  radical  polymerization  (atrp).  chemical  modifcation  of  the  clay  and transformation of...

The neutral organic dye indigo forms an inorganic-organic hybrid material with nanoclays (see picture; blue circles on disks symbolizing indigo, spheres indicating liberated cations) and can thus be transferred into aqueous solution. Solids recovered from these solutions resemble the ancient Maya Blue pigment. The method can also be applied to other hydrophobic species and may open the gate for...
