Mechanics of carbon nanotube reinforced nanocomposites

2014

Many numerical models have been developed in attempts to improve the understanding of the stiffening effects of CNTs in a polymer matrix. These studies are based on the micromechanical models, because the atomistic models are computationally too expensive to simulate the behavior of the composite. We emphasize that the majority of these continuum micromechanical models either explicitly or effectively adopt an assumption of an ideally-bonded interface between the compliant polymer matrix and the stiff CNTs, and often lead to predictions of overall composite stiffness that are quite optimistic compared to experimental results. Here the effects of waviness, diameter and volume fraction of CNT…

Recent Developments and Formulations for Hydrophobic Modification of Carrageenan Bionanocomposites

2023

Versatility of the anionic algal polysaccharide carrageenan has long been discussed and explored, especially for their affinity towards water molecules. While this feature is advantageous in certain applications such as water remediation, wound healing, etc., the usefulness of this biopolymer is extremely limited when it comes to applications such as food packaging. Scientists around the globe are carrying out research works on venturing diverse methods to integrate hydrophobic nature into these polysaccharides without compromising their other functionalities. Considering these foregoing studies, this review is designed to have an in-depth understanding of diverse methods and techniques ado…

Nanocarbon broadband analysis, temperature dependent dielectric properties and percolation thresholds

2013

The results of a broadband dielectric investigation of multi-walled CNT (MWCNT)/epoxy resin composites in wide temperature range from room temperature to 450 K are reported. Far below the percolation threshold (0.25 wt% MWCNT) the dielectric properties of the composite are mostly determined by alpha relaxation in pure polymer matrix. Close to the percolation threshold the composite shows the negative temperature coefficient (NTC) effect in the temperature region, where the pure polymer matrix becomes conductive. The activation energy increases with the MWCNT concentration far below the percolation threshold and decreases close to it (1.5 wt% MWCNT). The dielectric analysis of the MWCNT/epox…

Effect of graphene nanoplatelets on the photo-oxidative behavior of PP based nanocomposites

2018

The photo-oxidation behavior of polymer nanocomposites depends not only on the photo-oxidation behavior of the matrix, but also on the chemical composition and on the physical properties of the nanoparticles and on the possible interactions between the two phases. Graphene nanoplatelets (GnP) are short stacks of individual layers of graphite that, even at low contents, strongly affects many properties of the thermoplastic matrix. Indeed, by GnP adding, also at low filler concentration (< 5 wt.%), the mechanical, heat-resistance, thermal and electrical properties of the polymer matrix can be surprisingly modified. Of course, the effects of these nanoparticles on the properties of the poly…
