Supramolecular Modifications of Semicrystalline Polymers

Supramolecular interactions play an important role in defining the structure and the resulting mechanical properties of materials. For instance, interchain hydrogen-bonding in PAs gives them superior strength and stiffness in engineering materials, while t ...

Polymer Translocation through Nanometer Pores

Maria-Alexandra Paun

In this paper the loaded polymer transport and its escape via a nanometer size aperture, virtually by nanomembrane, the polymer being moved by an exterior electrostatic field, has been studied. Assuming a linear dependency of the friction coefficient on th ...

Morphology and interfacial strength of nonisothermally fusion bonded hard and soft thermoplastics

Pierre-Etienne Bourban, Rajasundar Chandran

Nonisothermally fusion bonded butt joints were prepared by overmolding thermoplastic elastomers (TPEs) onto isotactic polypropylene (iPP) inserts in order to investigate the effect of processing conditions on the bond strength and interfacial microstructur ...

Tuneable PTC effect in polymer-wax-carbon composite resistors

Peter Ryser, Thomas Maeder, Caroline Jacq, Ludivine Ammon

Purpose: The resistivity dependence on temperature of composite resistors made of carbon fillers dispersed in an organic matrix are known to be strongly affected by the matrix thermal expansion. High positive temperature coefficient (PTC) effects, i.e. ess ...

Hybrid Glass Mat-reinforced Polypropylene-Montmorillonite Nanocomposites

Véronique Michaud, John Christopher Plummer, Martyn Douglas Wakeman, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre

Polypropylene/montmorillonite (iPP/MMT) has been investigated as an alternative to isotactic polypropylene (iPP) as a matrix for glass mat thermoplastic (GMT) composites. The melt viscosity increased significantly on MMT addition, but iPP/5.9wt% MMT-based ...
