Rheological and Mechanical Properties of Epoxy Composites Modified with Montmorillonite Nanoparticles

Abstract

An examination is made of the effect of modifying montmorillonite with organic compounds and its ultrasound treatment on the rheological properties of filled epoxy oligomers and the structure and physicomechanical properties of cured composites. To improve the physicomechanical properties of filled epoxy composites, it is recommended that use be made of modified montmorillonite of grade Cloisite 30B, which has the best compatibility with the epoxy matrix.

Rheology and adhesive properties of filled PIB-based pressure-sensitive adhesives. I. Rheology and shear resistance

“…Since rheology of the suspensions is greatly affected by the polymer-particles interactions and by the distribution of the particles in the system -as shown in literature, [28,[30][31][32] rheological testing was selected for the indirect assessment of the systems structure.…”

A Study on the Structure and Adhesive Properties of Epoxy-Silicate Composites

“…As is known, the layered silicates are poorly compatible with hydrophobic polymers [24,25], but in many cases, the compatibility between a hydrophilic filler and a hydrophobic polymer can be improved by modifying the surface of silicate particles [4,12,15,16,18]. We should note that exactly the organomodified ММТ Cloisite 30B was used, for example, in [12,16,18,20] to modify an epoxy binder. It can be presumed that this process is favored by the hydroxyethyl groups of the Cloisite 30B modifier, which are able to interact with the relatively polar groups of epoxy oligomers [18].…”

“…Also, it was intended to estimate the dispersion quality of particles and the structure of the nanocomposites obtained. Since the rheological properties of suspensions with different particles are rather sensitive to the structure of the system, the size of particles, their shape, and conditions on their surface, rheology gives interesting possibilities for evaluating the dispersity of particles in polymers, as shown in [13][14][15][16][17][18][19][20].…”
