Synthesis and Magnetic Properties of Polyaniline-Based Magnetic Nanocomposites for EMI Applications

Renteria B., Singhal R., Calderon E., Tomar M.S., Banerjee J., University of Puerto Rico, PR

we have synthesized composite of polyaniline (PANI) with manganese-zinc-ferrite (MnXZn1-XFe2O4) nanoparticles. PANI was synthesized by polymerization of aniline in the presence of ammonium peroxydisulfate and HCl. Electrical conductivity of bare PANI pellets averaged 0.8044 (Ω·m)-1. [...]

Closed form Exact Analytical Solutions for Effective Mechanical Properties and Responses for Nanotube Reinforced Nanocomposites

Askari D., Ghasemi-Nejhad M., University of Hawaii at Manoa, US

In this paper, analytical and numerical approaches are employed to investigate the effective axial mechanical properties and mechanical behavior of a three-phase composite cylindrical model, representing a unit cell for a polymer nanocomposite reinforced by [...]

The Effect of Starch Structure on Starch-based Nanocomposite

Zhou J.H., Hanna M.A., South China Agricultural University, CN

The effect of starch structure on starch based nanocomposite Starches, including high amylose cornstarch, normal cornstarch, and waxy cornstarch, were gelatinized and mixed with nanoclay aqueous dispersion and different amount plasticizer. The mixtures were then [...]

Multifunctional Nanocomposites Made of Polypropylene Reinforced with Exfoliated Graphite Nanoplatelets (xGnP)

Kalaitzidou K., Fukushima H., Drzal L.T., Michigan State University, US

Polypropylene is one of the most widely used polymers. It is an attractive material because of its combination of mechanical properties, ease of processing and low cost. This research explores modification of polypropylene through addition [...]

Layer by Layer Fabrication of an Amperometric Nanocomposite Biosensor for Sulfite

Adeloju S.B., Ohanessian A., Water and Sensor Research Group, AU

This paper will present the results of a layer by layer strategy that we have developed for the fabrication of a polypyrrole nanocomposite amperometric biosensor for sulfite. The use of this strategy to fabricate bilayer [...]

Enzymatically Degradable Hydrogel Nanocomposite for Bone Regeneration

Jabbari E., He X., Sarvestani A.S., University of South Carolina, US

One approach to bone replacement involves the use of in-situ crosslinkable scaffolds for cell transplantation to promote tissue growth, nutrient diffusion, matrix production, and vascularization. Bone matrix is a composite material consisting of aqueous and [...]

Less Harmful Acidic Degradation of Poly(lactide-co-glycolide) Bone Tissue Engineering Scaffolds through Titania Nanoparticle Addition

Liu H., Slamovich E.B., Webster T.J., Purdue University, US

In the last ten years, biodegradable aliphatic polyesters, such as poly(lactide-co-glycolide) acid (PLGA), have attracted increasing attention for their use as scaffold materials in bone tissue engineering because their degradation products can be removed by [...]

Nylon – Exfoliated Graphite Nanoplatelet (xGnP) Nanocomposites with Enhanced Mechanical, Electrical and Thermal Properties

Fukushima H., Drzal L.T., Michigan State University, US

Since the late 1990’s, research has been underway in our group at Michigan State University to investigate the production, fabrication and modification of a new nano-sized carbon material, exfoliated graphite nanoplatelets [xGnP]. The xGnP is [...]

Aligned Electrospun Nanocomposite Fibers

Nartker S.R., Misra M., Drzal L.T., Research Assistant, US

Electrospun fibers have been used in various applications including filtration media, biomedical, ceramics and composites. Electrospinning uses an electric field to draw a polymer solution jet from the tip of a capillary to a collector [...]

New route to manufacture high performance carbon nanotubes nanocomposites based on pre-dispersed concentrates generated by in-situ polymerization

Claes M., Bonduel D., Pegel S., Alexandre M., Poetschke P., Dubois P., Luizi F., Nanocyl SA, BE

We describe here an original method which relies upon the in situ polymerization of olefin catalyzed by a highly active metallocene complex physicochemically anchored onto the carbon nanotube surface. As a result, carbon nanotubes are [...]
