Preparation of Hydrophilic Antifogging Film Materials by Silicate Minerals

Preparation and characterization of multifunctional magnetic mesoporous calcium silicate materials

We have prepared multifunctional magnetic mesoporous Fe-CaSiO3 materials using triblock copolymer (P123) as a structure-directing agent. The effects of Fe substitution on the mesoporous structure, in vitro bioactivity, magnetic heating ability and drug delivery property of mesoporous CaSiO3 materials were investigated. Mesoporous Fe-CaSiO3 materials had similar mesoporous channels (5-6 nm) with...

Mesoporous Silicate Materials in Sensing

Mesoporous silicas, especially those exhibiting ordered pore systems and uniform pore diameters, have shown great potential for sensing applications in recent years. Morphological control grants them versatility in the method of deployment whether as bulk powders, monoliths, thin films, or embedded in coatings. High surface areas and pore sizes greater than 2 nm make them effective as adsorbent...

Preparation and Characterization of Layered Silicate Polyethylene Terephthalate Nanocomposite by in Situ Polymerization

A series of experiments on the synthesis of poly (ethylene terephthalate) (PET)/organo-montmorillonite (MMT) nanocomposites were carried out in a pressurized reactor using alkyl ammonium exchanged smectite clays, (Closite 30B).Given the degradation of organoclay at high temperatures, the in situ polymerization process was carried out at mild temperatures ranging from 210 to 230°C for 40 minutes...

The Silica Tetrahedron and the Architecture of Silicate Minerals

With oxygen and silicon comprising approximately 85% of the atoms in Earth’s crust, most minerals in the crust include these two elements, and form the class of minerals called silicates. The basic building block of all silicate minerals is the silica tetrahedron, in which one silicon ion bonds with four oxygen ions. This arrangement of ions (coordination number of 4) is dictated by the ratio o...
