A Pressure Controlled Pinched Flow Fractionation Device for Continuous Particle Separation

Trosborg J., Christiansen T.L., Technical University of Denmark, DK

A demonstration of a pinched flow fractionation device that enables pressure controlled tuning of the separation range of particles. This makes the device ready for easy and cheap mass-production, maintaining great flexibility, and rendering the [...]

Injection molded superhydrophobic surfaces

Søgaard E., Smistrup K., Taboryski R., Technical University of Denmark, DK

The Lotus effect is used as inspiration for the fabrication of injection molded (IM) hierarchical polymer surfaces with self-cleaning properties. IM is a widespread method for the fabrication of plastic items. Surface functionalization is traditionally [...]

Nanostructured Stearic Acid for Gas sensing applications

Hullavarad N., Hullavarad S., Hullavarad N., Hullavarad S., University of Alaska Fairbanks, US

In this paper we report the fabrication of long chain polymer molecule Stearic Acid by physical vapor deposition method. Thin films of stearic acid are characterized by X-ray diffraction for the crystalline quality and by [...]

Advanced p- and n-Dopable Polymer Supercapacitors

Kim Y.-G., Kinlen P.J., Jung J.H., Mbugua J., Besic S., Birschbach M., Tregre G., Nguyen H.-L., Crosslink, US

Metallic conductive PAC 1003, an inherently conductive polymer product of Crosslink, has been developed to have remarkably high electrical conductivity of >1000 S/cm which can be applied to advanced polymer supercapacitor designs. The metallic conductivity [...]

Fracture-induced polymeric grating structures

Lin C.C., Yang F., Chin J.W., Sung L., Lee S., National Tsing Hua Univesity, TW

Fracture-induced structure (FIS)1 is found in the polymeric thin film sandwiched between two relatively rigid flat plates by inserting a razor blade at one edge. FIS is a potential candidate to be a low-cost and [...]

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 [...]

Adhesion strength and superhydrophobicity in polyurethane/organoclay nanocomposites

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

Polyurethane coatings are used on many different materials and in a wide variety of applications due to its high durability and adaptable chemical composition. Although there are a number of reports on the fabrication of [...]

Passive Microrheology : Non Intrusive Measurement of the Emulsions Stability

Tisserand C., Fleury M., Brunel L., Bru P., Brunel L., Meunier G., Formulaction, FR

This work presents a new technique of the passive microrheology for the study of the microstructure properties of soft materials like emulsions. Our technology uses Multi Speckle DWS (MS-DWS) set-up in backscattering with a video [...]

Transparent polymer photodetector to control electronic devices

Jeon K.M., Korea Advanced Institute of Science and Technology, KR

Polymer semiconductor materials are being used in variable applications such as OLED, OPV and Organic sensor, because polymer semiconductor materials have advantages like solution processing, low-cost, flexible, and easy large area fabrication. However, performance of [...]
