Novel Preparation And Properties Of Polypropylene

A novel approach to the preparation of polymer nanocomposites utilizing a low-molecular-weight reactive modifying reagent has been developed in this study. This is the first report on the fabrication of in situ nanocomposites using maleic anhydride as a reactive reagent that acts both as a modifying additive for the polymeric matrix and as a swelling agent for the silicate.

Sepiolite Ima Europe

Sepiolite, formerly known as Meerschaum sea froth, is a non-swelling, lightweight, porous clay with a large specific surface area. Unlike other clays, the individual particles of sepiolite have a needle-like morphology. The high surface area and porosity, as well as the unusual particle shape of this clay account for its outstanding sorption capacity and colloidal properties that make it a .

Fe2o3 Nanoparticlesvermiculite Clay Material

Photocatalysis is increasingly becoming a center of interest due to its wide use in environmental remediation. Hematite -Fe2O3 is one promising candidate for photocatalytic applications. Clay materials as vermiculite Ver can be used as a carrier to accommodate and stabilize photocatalysts. Two different temperatures 500 C and 700 degC were used for preparation of alpha-Fe2O3 .

Clay Mineral Interstratified Clay Minerals Britannica

Clay mineral - Clay mineral - Interstratified clay minerals Many clay materials are mixtures of more than one clay mineral. One such mixture involves the interstratification of the layer clay minerals where the individual component layers of two or more kinds are stacked in various ways to make up a new structure different from those of its constituents.

Role Of Epoxy Groups On Clay Surface In The

An organoclay containing epoxy groups, namely twice functionalized organoclay TFC, was successfully synthesized by reacting glycidoxypropyltrimethoxysilane with Cloisite25A C25A, which had previously been modified with an amine compound. The role of the epoxy groups on the clay surface in improving the morphology of the polyl-lactide PLLAclay composites was investigated.
