The filtration behaviour of some clay–water dispersions was studied. Two Spanish fibrous phyllosilicates (sepiolite from Vicálvaro and palygorskite from Turón) and a commercial bentonite (Bentopharm©, UK) with similar sizes and different morphologies (fibrous and/or laminar) were selected as model clays. Sepiolite from Vicálvaro is an almost pure fibrous sample, Bentopharm© presents a high amou...

In recent years, Pillared InterLayered Clays (PILCs) have been widely used in several applications; in particular in adsorption and catalysis. The research interest in this family of solids has increased considerably. Clay minerals provide distinct nanometer-scaled layers and interlayers for engineering them as active catalysts. As such, strategic design and preparation has led to a variety of ...

The search for renewable biodegradable materials to replace conventional oil-based plastics is a fast-growing research area as it provides an important factor the sustainable growth of packaging industry. In this regard, clay-containing composite have numerous current and potential commercial applications. However, interaction between clay polymer, i.e. Poly(ethylene glycol), influenced by many...

In 1993, researchers at Toyota Central R&D reported that 5 wt % of an exfoliated clay could double the roomtemperature modulus of nylon-6, a semicrystalline engineering plastic, and raise its heat distortion temperature by more than 80 °Call without sacrificing toughness. That work stimulated a worldwide effort to synthesize and study polymer–matrix nanocompositesand it also highlighted the i...

Tonsil Actisil FF, which is a commercial bentonitic clay, promotes the formation of cycloveratrylene macrocycles and benzyl oligomers from the corresponding benzyl alcohols in good yields under microwave heating and infrared irradiation in the absence of solvent in both cases. The catalytic reaction is sensitive to the type of substituent on the aromatic ring. Thus, when benzyl alcohol was subs...

In this work, the effect of distilled water, a biodiesel viscosity reducer, and commercial nonionic surfactant on apparent permeability clay-sand cores through analysis contact angle, linear swelling, porous media fluid flow for northern Mexico crude oil was evaluated. The results showed that clay content influences angle values having lower wettability in rocky medium. addition produces moveme...

The combination of Ethylene-vinyl acetate copolymer (EVA) with nanoclay has wide commercial applications (such as packaging films and cables), which depend on the vinyl acetate contained in the main chain. As the vinyl acetate content increases, the copolymer presents less crystallinity and different mechanical behavior. EVA with 40 wt% vinyl acetate content (EVA40)/ organoclay nanocomposites w...
