Effect of N-Isopropylacrylamide on the Structure and Swelling Behavior of Microporous Polyurethane Film
Microporous N-Isopropylacrylamide Polyurethane Solvent Swelling
2011/12/22
Preparation of membranes from stimuli-responsive polymers, copolymers, and polymer-additive mixtures is an important approach in the design of responsive membranes. N-isopropylacrylamide(NIPPAm) was d...
Gas Chromatographic Separation of Linear Hydrocarbons on Microporous Organo-Smectites
Gas chromatography Gas separation Hectorite Hydrocarbons Mesoporosity Microporosity Montmorillonite Organo-clays Smectites
2011/12/29
A series of organo-montmorillonites and organo-hectorites was prepared by complete ion-exchange from the pure sodium form of the parent smectites. The organic cations were tetramethylammonium, trimeth...
Synthesis of Highly Microporous and Hydrophilic Alumina-Pillared Montmorillonite: Water-Sorption Properties
Hydrophobicity Montmorillonite Pillared interlayer complex Porosity Surface condensation Thermal treatment X-ray powder diffraction
2012/1/4
A montmorillonite exchanged with large hydroxy-Al cations was thermally treated to convert the hydroxy cations to oxide pillars and to generate permanent microporosity in the interlayers. The pillared...
