The effect of nanoclay on various material properties like damping and strength of typical thermoset polymers, such as epoxy and vinyl ester, was investigated. Different environmental conditions typical for high-voltage transmission pylons made of composite materials were taken into account. Resin samples were prepared with various clay weight fractions ranging from 0% to 3%. Scanning electron ...

Bone tissue engineering implants with sustained local drug delivery provide an opportunity for better postoperative care for bone tumor patients because these implants offer sustained drug release at the tumor site and reduce systemic side effects. A rapid prototyped macroporous polycaprolactone scaffold was embedded with a porous matrix composed of chitosan, nanoclay, and β-tricalcium phosphat...

The influence of the bentonite content (1, 3, 5 wt%) on mechanical properties lightweightcotton (C), polyester (P) and polyester-cotton (P/C 50/50) fabrics was investigated. Starch used asa water-insoluble binder for coating fabrics. Bentonite nanoparticles were obtained by repeated hydration,decantation evaporation water dispersion. particle size determinedby XRD method using Debye-Scherrer eq...

The inherent safety and low cost of aqueous aluminum-air (Al-air) batteries have attracted significant attention. However, their lifespan is constrained due to the formation passive layers severe self-corrosion Al anode. This work addresses anode issues using an innovative design strategy by adding vanadate nanoclay modify interaction electrolyte. results shown that each vanadate, nanoclay, a h...

We report a methodology developed to detect and track stable fluorescent-labeled nanoclay, in polymer-clay nanocomposite films, and in a contact solvent after migration testing. Fluorescein-5-maleimide (fluorescein) or tetramethylrhodamine-5-maleimide (rhodamine) was covalently bonded to organically modified montmorillonite (o-MMT). Fluorescein- and rhodamine-labeled nanoclay showed good therma...

The purpose of this research is to simulate and test nanomaterial reinforced composites for potential applications in Army vehicles, especially for improved ballistic and blast protection. The resultant simulation and design system can address major concerns in functional requirements of nanomaterials in Army’s ground vehicles such as strength, durability, ballistic and blast impact resistance....

STATEMENT OF THE PROBLEM The mechanical and thermal properties of polymethyl methacrylate (PMMA) acrylic resin should be improved to counterweigh its structural deficiencies. PURPOSE The aim of this study was to compare the flexural strength and thermal conductivity of conventional acrylic resin and acrylic resin loaded with nanoclay. MATERIALS AND METHOD The methacrylate monomer containing...

Nanoparticle filling is a feasible way to increase the mechanical properties of polymer matrices. Abundant research work has been published in the last number of years concerning the enhancement of the mechanical properties of nanoparticle filled polymers, but only a reduced number of studies have been done focusing on the fatigue behaviour. This work analyses the influence of nanoclay reinforc...
