Effect of the chemical grafting of epoxy resin onto organomodified montmorillonite on the structure and heat resistance of an epoxy nanocomposite

Study of morphological and mechanical performance of amine‐cured glassy epoxy–clay nanocomposites

“…More recently, nanoclay fillers have drawn increasing interest as it is theoretically possible to significantly improve the properties of epoxy for relatively small additive amounts 1–20. The plausible reasons are the high aspect ratio (200–1000) and high modulus of these particles (170 GPa).…”

PLA-OMMT nanocomposites manufactured by reactive extrusion

“…Tethering reactive species onto the surface of the OMMT platelets seems to be a valuable methodology, as already reported by several authors [64][65][66]. Taking into account that the resultant performance of PLA-based nanocomposite products is strongly affected by clay dispersion and the processing technique, lab-scale equipment is unable to induce a similar thermomechanical history as large scale processing systems.…”

“…Figure 3 shows the change in FTIR absorbance spectra of the clay-chain extender samples as function of the reaction time. The absorption peaks of clay nanoparticles appear at 1011 cm −1 for Si−O stretching, 2925 and 2851 cm −1 for C−H stretching of the hydrocarbon chains of the organic ammonium ions, and 3626 cm −1 for the structural −OH stretching of both silanol groups (Si−OH) and the organic modifier (−CH 2 −OH) [64,72]. The absorption peaks of the chain extender were situated at 696 cm −1 for aromatic C=C vibration, at 762 cm −1 for aromatic C−H bending, at 798 cm −1 for epoxy ring bending, at 1492 and 1445 cm −1 for aromatic C−C vibration, and at 1720 cm −1 for C=O stretching [73].…”

Optimisation of the process of Producing Polyamide 6 and Aluminosilicate Nanocomposites based on it by the Method of Anionic Polymerisation

“…Most popular among silicate fillers for nanocomposite materials has been montmorillonite -a three-layer clay mineral with a layer thickness of 1 nm, a width of 50-500 nm, and a length of 200-800 nm. Owing to its developed surface area, which amounts to roughly 800-1400 m 2 /g, montmorillonite makes it possible to improve considerably different properties of the polymer at relatively low concentrations (1-5 wt%) [6] in the case of a uniform distribution in the material.…”
