A versatile new concept is presented for the synthesis of Janus colloids composed of Laponite nanoclay armored poly(divinylbenzene) with an anisotropic surface potential via a double Pickering emulsion template. First, polystyrene or poly(divinylbenzene) colloids stabilized with Laponite nanoclay are synthesized via a Pickering miniemulsion approach. These nanoparticle-stabilized colloids were ...

We report the energetics of association in polymeric gels with two types of junction points: crystalline hydrophobic junctions and polymer-nanoparticle junctions. Time-temperature superposition (TTS) of small-amplitude oscillatory rheological measurements was used to probe crystalline poly(L-lactide) (PLLA)-based gels with and without added laponite nanoparticles. For associative polymer gels, ...

The synthesis of Laponite®-based nanocomposite latexes by reversible addition-fragmentation chain transfer (RAFT)-mediated surfactant-free emulsion polymerization using different macroRAFT agents is described.

Two types of isotropic disordered nonergodic states exist in colloidal suspensions: glasses and gels. The difference between the two is that the nonergodicity, or elasticity, of gel stems from the existence of a percolated network, while that of glass stems from caging effects. Despite this clear difference in the origin of nonergodicity, it is not straightforward to distinguish the two states ...

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

Tremendous efforts are being made around the world to develop efficient ways prevent/treat novel β-coronavirus disease (COVID-19) caused by SARS-CoV-2. There currently many studies and clinical trials (either based on computational predictions or experiences), in progress, focusing finding relevant protein targets medications anti-COVID-19. In present study, we report a hydrogel drug delivery s...

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...

Hydrogels are 3D networks with an excellent ability to retain a high amount of water or biological fluids, representing suitable candidates for wound dressing applications. They can provide protective barrier and moist environment, facilitating treatment. The present paper focuses on physical hydrogels obtained from poly(vinyl alcohol) (PVA) pullulan (PULL) mixtures in different weight ratios b...

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...
