In recent years, polymer nano-composites (PNCs) have increasingly gained more attention due to their improved mechanical, barrier, thermal, optical, electrical and biodegradable properties in comparison with the conventional micro-composites or pristine polymers. With a modest addition of nanoparticles (usually less than 5wt. %), PNCs offer a wide range of improvements in moduli, strength, heat...

Electromechanical, adhesion, and viscoelastic properties of polymers and polymer nanocomposites (PNCs) are of interest for additive manufacturing (AM) and flexible electronics. Development/optimization of inks for AM is complex, expensive, and substrate/interface dependent. This study investigates properties of free standing films of a thermoplastic polyurethane (TPU) polymer and an Ag–carbon b...

It is well known that glassy polymer nanocomposites (PNC) exhibit heterogeneous mechanical properties, with a distinct polymer/nanoparticle (NP) interfacial region. The interphase rigidity in particular can significantly influence the overall response of PNCs. Continuum theories typically describe behavior such to depend only on deformation and, thus, they discard strong internal gradients with...

The inclusion of polymer-grafted nanoparticles (PGNPs) can impart various functional properties to polymer nanocomposites (PNCs). For semicrystalline polymers, we control the spatial dispersion PGNPs and presumably use it modulate nucleation rate polymer. In this work, correlation between quality poly(ethylene glycol) (PEG)-grafted silica (PEG-g-SiO2) crystallization ability oxide) (PEO) is sys...

Highly ordered polymer nanocomposites are complex materials that display a rich morphological behavior owing to variations in composition, structure, and properties on a nanometer length scale. Metal-polymer nanocomposite materials are becoming more popular for applications requiring low cost, high metal surface areas. Catalytic systems seem to be the most prevalent application for a wide range...

Abstract Polymeric blends and nanocomposites with improved functional properties have attracted attention worldwide for industrial applications. For food packaging applications carrying purposes, the materials to be used should UV blocking ability, antibacterial activity, good mechanical properties. In this study, polyvinyl acetate (PVAc)/polyvinyl chloride (PVC) optimized MgO/PVAc/PVC polymer ...

Poly (o-Phenylenediamine) and its ZnO nanocomposites were synthesized at different concentrations metal oxide like 5%, 10% and 15% of ZnO by via chemical oxidative polymerization method using ammonium persulphate as an oxidant in the presence of HCl. The prepared polymer and its polymer nanocomposites are found to be soluble in common organic solvents like ethanol, DMSO, toluene etc. The format...

Targeting of diagnostic and therapeutic agents to endothelial cells (ECs) provides an avenue to improve treatment of many maladies. For example, intercellular adhesion molecule 1 (ICAM-1), a constitutive endothelial cell adhesion molecule up-regulated in many diseases, is a good determinant for endothelial targeting of therapeutic enzymes and polymer nanocarriers (PNCs) conjugated with anti-ICA...

this paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10a and biodegradable polymer chitosan by solution mixing technique and their characterization. the nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (xrd), particle size analyzer (beckm...

The use of non-toxic and low-cost vitamins like α-tocopherol (α-TCP, vitamin E) to improve the photophysical properties stability perovskite nanocrystals (PNCs), through post-synthetic ligand surface passivation, is demonstrated for first time. Especially interesting its effect on CsPbI3 most unstable inorganic PNC. Adding α-TCP produces that photoluminescence quantum yield (PLQY) freshly prepa...
