The demand for robust hydrogels in pharmaceutical, biomedical, and industrial applications has motivated intense research efforts in these wet polymeric materials. Recent advances have resulted in different strategies for creating highly stretchable polymeric hydrogels, including sliding-ring gels (SR gels), nanocomposite gels (NC gels), doublenetwork gels (DN gels), macromolecular microsphere ...

Nanoscale control of structure in polymer nanocomposites is critical for their performance but has been difficult to investigate systematically due to the lack of a suitable experimental model. In this work, we investigated the role of nanoparticle layer separation in the finite deformation response of layered polyurethane(PU-) montmorillonite (MTM) nanocomposites. A series of multilayered nano...

In this work, Ni nanoparticles were directly decorated on graphene (G) nanosheets via mechanical ball milling. Based on transmission electron microscopy observations, the Ni nanoparticles were well dispersed and attached to the G nanosheet without any agglomerations. Electrochemical results showed that the capacitance of a G/Ni nanocomposite was 275 F g(-1) at a current density of 2 A g(-1), wh...

MXene is a new type of two-dimensional layered material. Herein, a GO/Ti₃C₂Tx nanocomposite was prepared by a simple liquid phase method, and the obtained GO/Ti₃C₂Tx was transformed into RGO/Ti₃C₂Tx under high temperature with Ar/H2. The prepared samples were characterized using X-ray diffraction (XRD), Raman measurement, scanning electron microscopy (SEM), energy disperse spectroscopy (EDS), a...

We report here the field emission studies of a layered WS2-RGO composite at the base pressure of ~1 × 10(-8) mbar. The turn on field required to draw a field emission current density of 1 μA/cm(2) is found to be 3.5, 2.3 and 2 V/μm for WS2, RGO and the WS2-RGO composite respectively. The enhanced field emission behavior observed for the WS2-RGO nanocomposite is attributed to a high field enhanc...

In this paper, ultrasonic irradiation was applied for the synthesis of K2Ti6O13 nanobelts and novel nanocomposite (PbS-CdS/Ti6O13) through ion exchanging and co-intercalation processes. Thirty minutes of ultrasonic irradiation caused the formation of pure, uniform potassium hexatitanate with smaller particle size. The incorporation of PbS and CdS nanoparticles into the layers and on the surface...

Nanostructured composite sorbent of Mg/Al-aminobenzoate layered double hydroxide was prepared by coprecipitation method. The particle size of the nanocomposite was found to be 10-20 nm. Sorption performance of the prepared material was studied for removal of cobalt ion from aqueous solution. The percent uptake of cobalt ion was found to be 96.1%. The loading capacity of Mg/Alaminobenzoate compo...

In this work, we report a dielectric nanocomposite paper with layered boron nitride (BN) nanosheets wired by one-dimensional (1D) nanofibrillated cellulose (NFC) that has superior thermal and mechanical properties. These nanocomposite papers are fabricated from a filtration of BN and NFC suspensions, in which NFC is used as a stabilizer to stabilize BN nanosheets. In these nanocomposite papers,...

The in vitro cytocompatibility of silicate (Laponite clay) cross-linked poly(ethylene oxide) (PEO) nanocomposite films using MC3T3-E1 mouse preosteoblast cells was investigated while cell adhesion, spreading, proliferation and mineralization were assessed as a function of film composition. By combining the advantageous characteristics of PEO polymer (hydrophilic, prevents protein and cell adhes...
