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.

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.
- Contribution of High-shear Processing to the Compatibilization of (PP/EPR)/PE Ternary Blends
Molka Louizi, Valérie Massardier and Philippe Cassagnau

This paper focuses on the compatibilization of high impact polypropylene/high density polyethylene (PP/EPR)/PE blends by using new high shear process. All (PP/EPR)/PE blends reveal a ‘PE/EPR’ dispersed phase formed by a core–shell structure, comprising a PE-rich core and an EPR outer shell, within PP matrix. Interestingly, the addition of ethylene-octene copolymer (EOC) to the processed blend at 600 rpm increases elongation at break and impact strength.
