Hydraulic Conductivity of Organoclay and Organoclay-Sand Mixtures to Fuels and Organic Liquids [PDF]
Journal of Geotechnical and Geoenvironmental Engineering, 2015 Abstract Hydraulic conductivity, swelling, and liquid sorption capacity (i.e., maximum organic liquid mass bound per mass organoclay solid) were measured for an organoclay with dimethylammonium bound to the surface. Five fuels (No. 1 fuel oil, No. 2 fuel oil, diesel, jet fuel, and gasoline), four pure organic liquids (methanol, phenol, ethylbenzene ...

Journal of Applied Polymer Science, 2005 AbstractWe prepared polypropylene nanocomposites based on a modified organoclay with isobutyl trimethoxysilane to investigate the effects of such modifications of organoclay on the microstructure and properties of the nanocomposite. The organoclay was preliminarily intercalated with distearyldimethylammonium bromide via an ion exchange before being ...

Reinforcement of dynamically vulcanized EPDM/PP elastomers using organoclay fillers
Science and Technology of Advanced Materials, 2008 Dynamically vulcanized EPDM/PP (ethylene-propylene-diene/polypropylene) elastomers reinforced with various amounts of organoclay were prepared using octylphenol-formaldehyde resin and stannous chloride dehydrate as vulcanizing agents.

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 ...

Ambient Stable Triboelectric Nanogenerator Based on Conductive Filler Modified Silicone Rubber with Gas Barrier Encapsulation for Footstep Energy Conversion. [PDF]
Adv Sci (Weinh)A humidity‐tolerant triboelectric nanogenerator is developed using conductive carbon black‐modified silicone rubber and a flame‐retardant gas barrier layer. The device efficiently harvests footstep energy while maintaining stable output under 30–90% RH and over 1 million cycles.

Organoclay Derivatives in the Synthesis of Macrocycles
Angewandte Chemie International Edition, 2001 As an alternative to the rotaxane method, an organoclay can be used as a template for the efficient formation of macrocycles (ring in schematic representation) which are easily extracted from the clay interlayer space. The four-step synthesis involved preparation of a pillared clay from the dihydrochloride salt of p-xylylenediamine, insertion of ...

Organoclay-polymer nanocomposites [PDF]
Zastita Materijala, 2014 The properties of polymer nanocomposites exceed the properties of common composite materials due to the nanoscale size and morphology of the fillers used. Particulate fillersare commonly used in polymers forimproved mechanical and thermal properties, as well as modified electrical properties and cost reduction.

Triadimefon Interactions with Organoclays and Organohydrotalcites
Soil Science Society of America Journal, 2000 We determined the ability of several organoclays (octadecylammonium‐ and hexadecyltrimethylammonium‐exchanged montmorillonite) and organohydrotalcites (dodecylsulfate‐ and dodecylbenzenesulfonate‐exchanged hydrotalcite) to sorb the uncharged pesticide triadimefon [1‐(4‐chlorophenoxy)‐3,3‐dimethyl‐1‐(1 H
