- Bis(trifluoromethanesulfonyl)imide-Type Ionic Liquids as Excellent Antistatic Agents for Polyurethanes

Surface resistivity (ρs) of polyurethane (PU) films is reduced by the addition of bis(trifluoromethanesulfonyl)imide type ionic liquids (ILs). This effect is attributed to ionic conductivity derived from low glass transition temperature of both polyether network in the PU films and the ILs. Additionally, the reduced ρs of PU films is retained even after methanol washing.

Biaxial melt-drawing produced a high-performance poly(tetrafluoroethylene) (PTFE) membrane with excellent mechanical properties and superior transparency. Unique two-step molding gave the better adhesion between the PTFE powder materials even with ultra-high molecular weight of 107. Such void-free film could be successfully biaxially drawn in the molten state. The resultant membrane exhibits high tensile strength of 120 MPa and high transparency of 8.5% haze.

- Microfluidic-Assisted Synthesis of Waterborne and Solvent-Free Urea-Crosslinked Polydimethylsiloxane Microparticles
Adrien Dalmais, Christophe A. Serra, Zhenqi Chang, Michel Bouquey and René Muller
Article first published online: 25 NOV 2013 | DOI: 10.1002/mame.201300279
Double droplets of isocyanate core and dicarboxylic-acid-functionalized silicon oil or PDMS-amide prepolymer shell in water are produced by means of a capillary-based microfluidic process. This drop-in-drop stucture allows avoiding direct contact of isocyanate groups with water and results in the waterborne and solvent-free formation of urea-crosslinked PDMS microparticles having an extremly narrow size distribution.
- Electrical Conductive Adhesives Enhanced with High-Aspect-Ratio Silver Nanobelts

Novel high-aspect-ratio silver nanobelts (NBs) are used with typical silver micron flakes to develop advanced electrical conductive adhesive (ECA) composite materials. The synthesis of the NBs is based on self-assembly and room temperature joining of hexagonal and rectangular silver nanoparticles. Addition of a small amount of the Ag NBs into conventional ECAs results in a significant improvement of the electrical conductivity.
