Role of Hard Segment Induced Nanosized Domain on Dilute Solution Properties of Ether Based Thermoplastic Polyurethanes

Lem K.W., Lee D.S., Haw J.R., Song G.S., Curran S., Sund S., Iqbal Z., Brumlik C., Konkuk University, KR

Many useful polyurethane components, such as films, are prepared from solution, in the form of dispersion, emulsion, or suspension. The ultimate properties of such films depend on the effect of nano scaled structures in the [...]

Durability Study of Nanophased Jute-Based Green Composites

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Tuskegee University, US

Jute fiber reinforced biopol biocomposites with and without nanoclay were manufactured using treated and untreated jute fibers by a compression molding process and their durability study was performed using standard moisture absorption and flexure tests [...]

Layer by layer control of wettability in nanocomposite films

Villafiorita Monteleone F., Center for Biomolecular Nanotechnologies @ UNILE, IIT, IT

We propose an original method to modify and control the surface wettability properties of a specific material, by creating nanocomposite films on substrates with different surface properties, where the number of the deposited layers defines [...]

Surface Modification of Iron Oxide (Fe3O4) Micro- and Nano-particles with Stimuli Responsive Polymers

Vasquez E.S., Nicholson W.B., Walters K.B., Mississippi State University, US

In this work, the synthesis of stimuli responsive polymer brushes was carried out using surface-initiated atom transfer radical polymerization (ATRP) on iron oxide (Fe3O4) micro- and nano-particles. Bare Fe3O4 nanoparticles (20 nm nom. d(H)) were [...]

Spontaneous Liquid Flow in Microfluidic Systems by Gradual UV Irradiation of the Hybrid Polymer/TiO2 Nanorods Channels

Athanassiou A., Center for Biomolecular Nanotechnologies @ UNILE, IIT, IT

PMMA coatings enriched with colloidal TiO2 nanorods are found to exhibit a remarkable increase in their water wettability when irradiated with UV laser light. The effect can be completely reversed using successive storage in vacuum [...]

Poly(butyl terephthalate)/oxytetramethylene + oxidized carbon nanotubes hybrids: mechanical and tribological behavior

Brostow W., Broza G., Datashvili T., Kopyniecka A., TUHH, DE

Carbon nanotubes (CNTs) have been used for providing mechanical reinforcement to polymers [1, 2] – as have been other approaches. Much less attention than to mechanics has been paid to improvement of tribological properties of [...]

Silica–Polyacrylate Nanocomposite Pressure Sensitive Adhesives

Shanks R., RMIT University, AU

The aim of this research is to increase cohesion of a PSA by including silica nanoparticles. The silica nanoparticles form reversible agglomerates and bind polymer molecules by adsorption. The adhesive becomes a reversible gel. Under [...]

Fabrication of nanostructured microworms for sensor applications

Yagüe J.L., Dubach J.M., Ozaydin-Ince G., Clark H.A., Gleason K.K., Massachusetts Institute of Technology, US

A novel method to create in vivo sensors for multiple types of ions and molecules is presented. Using initiated Chemical Vapor Deposition (iCVD), a gentle process which preserves functional pendant groups and enables conformal coatings, [...]

Magnetically Induced Drop Movement on Nanorough Micropatterned Nanocomposites

Milionis A., Fragouli D., Anyfantis G.C., Bayer I., Cingolani R., Athanassiou A., Italian Institute of Technology, IT

Hybrid organic/inorganic surfaces are engineered by exploiting photo-lithographically tailored patterns of SU-8 polymer nanocomposites containing 2% wt colloidal nanoparticles of iron oxide. The role of the magnetic nanoparticles has two aspects. The first one is [...]

Controlling pH responsive polymersome assembly

Pearson R., Battaglia G., University of Sheffield, UK

Size is an important parameter in delivery systems. It plays a part in whether a particle avoids filtration, evades immune cell binding and by which internalisation pathways are available. However, it is hard to obtain [...]
