Two new mesogenic monomers, namely 3,3’-dimethoxy-4,4’di(hydroxyhexoxy)-N-benzylidene-o-Tolidine (Ia) and 4,4’-di(6-hydroxyhexoxy)-Nbenzylidene-o-Tolidine (IIa), were reacted with cadmium sulfide (CdS) via an in situ chemical precipitation method in ethanol to produce CdS nanocomposites. A series of different mass compositions of CdS with Ia and IIa ranging from 0.1:1.0 to 1.0:1.0 (w/w) were pr...

In this research, Novel UV curable conductive nanocomposites containing urethane acrylate and PANi-Co3O4 nanocomposite have been prepared. At first, PANi- Co3O4 nanocomposites have been synthesized and then PUA-PANi-Co3O4 nanocomposites films were prepared by ultraviolet radiation. UV-Vis and FT-IR studies confirm that there was strong chemical interaction between PANi and Co3O4 nanoparticles, ...

In this work, a synergistic effect of reduced graphene oxide (rGO) and polypyrrole (PPy) was studied in terms of their promotional role to enhance the capacity and cyclic stability of hollow SnO2 anodes in lithium-ion batteries. The core–shell structured hollow SnO2/rGO/PPy nanocomposites were synthesized using a hydrothermal method followed by an in situ chemical-polymerization route. Substant...

Thermoplastic polyurethane (TPU)/clay nanocomposites were prepared via a melt-compounding method using ester type TPU and two different modified organoclays (Cloisite 30B and Cloisite 15A) in different contents. The Effects of the chemical structure and content of the nanoclays on the thermal degradation and mechanical properties of TPU were also investigated. The effect of structural modificat...

Iron oxide nanostructures (IONs) in combination with graphene or its derivatives-e.g., graphene oxide and reduced graphene oxide-hold great promise toward engineering of efficient nanocomposites for enhancing the performance of advanced devices in many applicative fields. Due to the peculiar electrical and electrocatalytic properties displayed by composite structures in nanoscale dimensions, in...

in this work, a thermoplastic polyurethane elastomer (tpue) model based on polytetramethylene glycol, toluene diisocyanate and 1,4-butanediol was selected and synthesized. according to this model two types of polyurethane nanocomposites were prepared by in situ polymerization and melt intercalation procedures. the organo-modified nanoclay was used in nanocomposites samples in 0.4 weight percent...

Carbon nanotube (CNT)-based nanocomposites often possess properties such as high stiffness, electrical conductivity, and thermal stability and have been studied for various biomedical and biotechnological applications. However, the current design approaches utilize CNTs as physical fillers, and thus, the true potential of CNT-based nanocomposites has not been realized. Here, we introduce a gene...

Epoxy-based nanocomposites were fabricated with different content of colloidal silica nanoparticles such as 10.0, 20.0 and 30.0 wt %, through solution casting. The covalent bonding interfaces, resulting from a ring-opening reaction between silica nanoparticles and epoxy matrix were confirmed by the Fourier transform (FT-IR) infrared spectroscopy. These nanocomposites were characterized for ...
