Effect of Dispersion Conditions on the Thermo-Mechanical Properties of Functionalized Carbon Nanotube-Reinforced Vinyl Ester

Sabet S.M., Mahfuz H., Hashemi J., Florida Atlantic University, US

To date, controlling the microstructure of carbon nanotube (CNT)-polymer composites remains a challenge due to high tendency of CNTs to aggregate. Proper dispersion of CNTs in the matrix has to be guaranteed to employ CNTs [...]

Probing Critical Particle to Polymer Size Ratios for Non-Einstein Behavior in Polymer Nanocomposites

Schmidt R.G., Gordon G.V., Swier S., Cosgrove T., Dow Corning Corporation, US

Enhanced studies of polymer nanocomposites(PNCs)has led to multiple discoveries of PNC's that exhibit viscosity behavior counter to the classical behavior for filled systems originally defined by Einstein(1). Opposed to the viscosity increase typically observed for [...]

Hybrid Materials made up of Ionic Liquids Confined in Porous Silica and Chalcogenide

Ori G., Villemot F., Viau L., Vioux A., Massobrio C., Coasne B., UMI CNRS / Massachusetts Institute of Technology, US

Hybrid materials made up of an inorganic porous material filled with a room temperature ionic liquid (IL) represent a novel class of materials with promising applications. The structure and dynamics of IL confined in amorphous [...]

Controlling Alignment in Cellulose Nanocrystal Coatings

Haywood A.D., Ashurst R.W., Davis V.A., Auburn University, US

Investigations on the rheology and phase behavior of aqueous CNC dispersions have been used to develop processes for making CNC coatings with controlled properties. We report how the interplay between dispersion microstructure, shear, and drying [...]

Preparation and characterization of SAPO-34 nanoparticles-mixed matrix membranes (MMM) via combined phase separation method for CO2/CH4 gas separation application

Jahanbakhsh Asl H., Soltanieh M., Azadi R., Sharif University of Technology, IR

Mixed matrix membranes (MMM) comprising of SAPO-34 zeolite nanoparticles in polyethersulfone (PES) matrix were fabricated via combined TIPS/NIPS phase separation method, which is critical for membrane performance, were synthesized and characterized. The performance of the [...]

Effect of Support Structure on Permeance of Thin Film Composite Membranes

Ponnuru K., Lin H., Furlani E.P., SUNY-Buffalo, US

The production of potable water has become a worldwide concern to meet the demand of a growing population. The reverse osmosis (RO) membrane is the leading technology for desalination installations to produce drinkable water, due [...]

Merino Wool Surfaces Made Superhydrophobic

Herzog M.B., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

Natural merino wool fibres have been used to fabricate wash-fast nonwoven textile surfaces with superhydrophobic and oleophobic properties. Wet felted samples were used to study the effect of the fibre diameter and the degree of [...]

Mechanically Durable Superhydrophobic Nanocomposites from Acrylonitrile Butadiene Styrene (ABS)

Milionis A., Yeong Y.H., Loth E., Bayer I.S., University of Virginia, US

We report on the development of nanocomposites based on a combination of ABS with hydrophobically modified fumed silica (HMFS). By tuning the ratio between the two materials we are again able to obtain static water [...]

3D Printered and Plasma Treated Superhydrophobic Mesh Filters for Oil-water Separation

Lee H.J., Lee S., Jo W., Lee H.J., Lee S., Moon M.-W., Korea Institute of Science and Technology, KR

We develop the 3D printed mesh filters with plasma treatment using a radio-frequency plasma-enhanced chemical vapor deposition (rf-PECVD) to control their surface wettability. The nano-sclae hairy structures on the meshes are created by plasma etching [...]

Bio-Inspired Multi-gradient Structure Surfaces for Water Collection/Repellency

Zheng Y., Beihang University, CN

Biological surfaces with micro- and nanostructures display unique wetting functions. Since spider silk collects water through a combination of multiple gradients in a periodic spindle-knot structure after wet-rebuilding process, a series of functional fibers with [...]
