Nanoclay has proven to be an active anti-corrosive additive due the self-repairing effect from nanoclay swelling and expansion, except for its passive barrier high aspect ratio. But it is still uncertain how these effects of are intertwined with other components in a complex coating system corrosive environments. In this study, we examined combined nanoclays two particle sizes commonly used cos...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

This paper reports the dispersion of nanoclay in vinylester using co-rotating twin screw extrusion and ultrasonication for preparing nanoclay/vinylester gel coat. Two sets MMT/vinylester specimens, namely Type 1 2 were prepared comparative studies. While specimens only, both twin-screw extrusion. showed lower levels intercalation higher exfoliation. By coat so by two different routes, MMT/vinyl...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....

In this work, organomodified nanoclay has been used as the adsorbent for the removal ofbasic blue 41, cationic dye from an aqueous solution. The performance of the organomodified nanoclay was tested in a batch system under varying pH (2–12), adsorbent dosage (0.1–2 g L-1), initial dye concentration (10–60 mgL-1), and contact time (5- 100 min). The best conditions were achieved at pH of 7,...

different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. the coatings were applied on low carbon steel plates. optical microscopy, sedimentation test, transmission electron microscopy, and x-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. the corrosion resistance of coatings was evaluated by electrochemical...

Nanocomposites of poly(lactic acid) with sepiolite needles (5 wt.%) were evaluated in terms the mechanical and biofilm formation properties. The nanocomposite exhibited higher values Young�s modulus tensile strength at break compared to PLA, without detriment percent elongation break. These improvements related high aspect ratio nanoclay, polymer-clay interactions, degree dispersion. growth Pse...

Inverse vulcanisation stabilises polymeric sulfur to synthesise high content polymers. vulcanised polymers were reinforced with carbon black, cellulose microfibres and nanoclay increase tensile strength.
