Electrical conductivity of carbon nanopowder fillers and their respective polymer composites prepared via latex technology

Ghislandi M., Marinho B., Tkalya E., Koning C.E., de With G., Eindhoven University of Technology, NL

The electrical conductivity of graphene, multi-wall carbon nanotubes (MWCNTs) and carbon black (CB) nanopowders, and graphite powder is characterized in the form of paper-like films (buckypapers) and by means of powder compression. Subsequently, carbon filler [...]

Using liquid crystals to improve the performance of luminescent solar concentrator

Debije M., Eindhoven University of Technology, NL

The luminescent solar concentrator (LSC) has been proposed as a cost-effective solution to bring electricity generation from sunlight into the built environment. The basic LSC design consists of a plastic plate containing or topped by [...]

Chaotic mixing using periodic and aperiodic sequences of mixing protocols in a micromixer

Kang T.G., Singh M.K., Kwon T.H., Anderson P.D., Eindhoven University of Technology, NL

We conducted a numerical study on mixing in a barrier embedded micromixer with an emphasis on the effect of periodic and aperiodic sequences of mixing protocols on mixing performance. A mapping method was employed to [...]

Chaotic advection induced by a magnetic chain in a rotating magnetic field

Kang T.G., Hulsen M.A., Anderson P.D., den Toonder J.M.J, Meijer H.E.H., Eindhoven University of Technology, NL

We investigated chaotic advection induced by a magnetic chain suspended in a fluid in a rotating magnetic field. Our main focus is on the dynamics of the chain and the route to induce chaotic mixing, [...]

Dissolution of Hydrogen Bonded Polymers in Water: From Synthetic to Biopolymers

Rastogi S., Vinken E., Harings J., Yin J., Terry A., Eindhoven University of Technology, NL

The field of supramolecular materials explores the use of intermolecular, non-covalent bonding to obtain novel self-assembled structures. Self-assembly is a method of spontaneous organisation of molecules into higher order structures ranging from the nano to [...]

Morphological Implications of the Interphase; Linking Crystalline and Amorphous Regions in Semi-Crystalline Polymers

Rastogi S., Terry A.E., Eindhoven University of Technology, NL

In semi-crystalline polymers, a range of morphologies can be obtained in which a chain may traverse the amorphous region between the crystals or fold back into the crystals leading to adjacent or non-adjacent re-entry, depending [...]

Conductive Carbon-Nanotube/Polymer Composites: Spectroscopic Monitoring of the Exfoliation Process in Water and the Crucial Role of Wetting

Grossiord N., Loos J., Meuldijk J., Regev O., Miltner H.E., Van Mele B., Koning C.E., Eindhoven University of Technology, NL

For the preparation of conductive polystyrene/SWNT nanocomposites, a recently developed, versatile, latex-based technology is applied. A low molar mass PS fraction, probably acting as a wetting agent for the SWNTs, seems to be required for [...]

Dispersion and rheological aspects of SWNTs in ultra high molecular weight polyethylene

Zhang Q., Lippits D.R., Vaidya S.N., Rastogi S., Eindhoven University of Technology, NL

A new method is developed to homogeneously disperse single-walled carbon nanotubes bundles (SWNTs) in an intractable polymer, for example, ultrahigh molecular weight polyethylene (Mw>3*106 g/mol) (UHMWPE). The dispersion is obtained by spraying an aqueous solution [...]
