The paper describes the manufacturing, testing and modelling of a class of open cell polyurethane foams doped with multi-walled carbon nanotubes and nano polyurethane dispersions and subjected to quasi-static cycling compressive loading at large deformations. The doped nano-ink foams are produced using a multiple steps dip coating technique that ma...

An overview on static and dynamic behavior of functional polymeric foams is presented. In particular, a PU (Poly Urethane) open cells foam was manufactured to obtain specimens with different nanostructured coatings. An experimental campaign was performed with 7 different kind of multilayer coatings. Quasi-static compression preconditioning and co...

This work presents a mechanism to generate energy dissipation by creating novel multilayer microstructure architectures via nano-inks and improve the mechanical, damping and dielectric performance of open cell foams. A multilayer carbon nano-ink containing –COOH functionalised multi-walled carbon nanotubes are produced and used to dip-coat pristine...

The improvement of the viscoelastic damping performance at small dynamic strains through interfacial slippage in polymer composites dispersed with carbon nano-fillers has been widely reported. This study utilised another mechanism to create frictional energy dissipation in high density nano-filler regions to improve damping performance of an open c...

Flexible pressure sensors are crucial components for the next generation wearable devices to monitor human physiological conditions. In this paper, we present a novel resistive pressure sensor based on hybrid composites made from carbon nanotube (CNT) for the conductive coating layer and polydimethylsiloxane (PDMS) elastomers as the substrate. The...

This work describes the effects of tailoring the morphology of the re-agglomeration network and interfacial bonding by embedding poly(methyl methacrylate) decorated single wall nanotubes (SWNTs) into an epoxy resin. We report the time history of the re-agglomerations in the resin, and the rheological properties of the uncured suspensions to assess...

For over a decade, carbon based nanotubes have been considered as nano scaled fillers for potential reinforcement for polymers due to their exceptional mechanical properties. Re-agglomeration is a natural phenomenon in which the initially dispersed carbon nanotubes (CNTs) have the natural tendency to form a secondary agglomeration network during th...

Abstract Re-agglomeration is a natural phenomenon occurring in certain processing methods used in the fabrication of nanocomposites. The work describes the tailoring of the interfacial bonding and morphology in the re-agglomeration of Cup Stacked Carbon Nanotubes (CSNTs) modified RTM6 epoxy nanocomposite for potential damping applications.
