Sorption of Bisphenol a as Model for Sorption Ability of Organoclays [PDF]
Molecules, 2022 The arrangement of bisphenol A molecules into organoclays and their interactions with the intercalated surfactant were studied. The organoclays were prepared via solid-state intercalation of four cationic surfactants, such as dodecyltrimethyl ...

Organoclay reinforced polyimide hybrid films based on hexadecyl modified montmorillonite and synthetic mica [PDF]
Scientific ReportsPoly(amic acid) (PAA) was synthesized via the polycondensation of 4,4′-oxydiphthalic anhydride and 3,3′-dihydroxybenzidine, followed by the incorporation of organoclays and subsequent multistep thermal imidization to fabricate polyimide (PI) hybrid films.

Surface Structure of Organoclays [PDF]
Angewandte Chemie, 2004 The properties of organically modified clay minerals determine essentially the quality of polymer-clay nanocomposites. We investigate alkylammonium-micas with different alkyl chain length by molecular dynamics simulation as homogeneous mixtures and separated island structures on the mica surface (80 percent alkali exchange, 20 percent of the alkali ...

An investigation on non-isothermal crystallization behavior and morphology of polyamide 6/ poly(ethylene-co-1-butene)-graft-maleic anhydride/organoclay nanocomposites [PDF]
Polyolefins Journal, 2015 Nanocomposites based on polyamide 6 (PA6) and poly(ethylene-co-1-butene)-graft-maleic anhydride (EB-g- MAH) blends have been prepared via melt mixing. The effect of blend ratio and organoclay concentration on the crystallization and melting behavior of ...
