Characterization of Methyltrimethoxysilane Sol-Gel Polymerization and the Resulting Aerogels.
… used to follow the structural evolution of MTMS (methyltrimethoxysilane) polymerization to gelation or precipitation, and thus to better understand the species that affect these properties and gelation behaviors. The effects of pH, water concentration, type of solvents, and synthesis procedures …

Polyimide-Organosilicate Hybrid Materials: Part I: Effects of Annealing on Gas Transport Properties; Part II: Effects of CO2 Plasticization
… partially hydrolyzed tetramethoxysilane (TMOS), methyltrimethoxysilane (MTMOS) or phenyltrimethoxysilane (PTMOS). The first study subjected the hybrid membranes to a 400°C annealing process to enhance gas separation performance by altering the organosilicate structures. The hybrid membranes were …

Surface Characteristics of Silica Polyamine Composites
… materials. Initial materials were formed using methyltrimethoxysilane (MTMOS) and 3-chloropropyltrimethoxysilane (CPTMOS). Some control over surface morphology was achieved by adjusting synthetic conditions. Due to relatively low metal capacities, tetramethoxysilane (TMOS) was introduced as a …

BISMUTH-FUNCTIONALIZED SORBENTS FOR RADIOIODINE CAPTURE
… made with tetraethoxysilane (TEOS) and TEOS + methyltrimethoxysilane (MTMS) silica precursor. Oil concentrations of 9.09 v/v% and 33.33 v/v% were studied. The miscibility of the oil and precursor decreased as the silica gel network formed, leading to oil-rich regions within the silica matrix. …

Physical and Gas Permeation Properties of a Series of Novel Hybrid Inorganic-Organic Composites Based on a Synthesized Fluorinated Polyimide
… tetraethoxysilane (TEOS), tetramethoxysilane, methyltrimethoxysilane (MTMOS), and phenyltrimethoxy-silane (PTMOS) employing the sol-gel process. Polyimides were synthesized from 4,4'-hexafluoroisopropylidene dianiline (6FpDA) and 4,4'-hexafluoroisopropyl-idenediphthalic anhydride (6FDA) …
