Patent number: 10981830Abstract: The present invention is directed to processes for preparing a silicone surfactant intercalated clay and a polymer-clay nanocomposite. The processes use silicone surfactants having a molecular weight in the range of 10,000 to 100,000 Dalton to achieve fully exfoliating clay structures. Using these macromolecular silicone surfactants, along with the engineered control of the processing pH and drying stress conditions, this invention provides simple and low-cost methods of making a fully-exfoliated polymer-clay nanocomposite.Type: GrantFiled: July 22, 2019Date of Patent: April 20, 2021Assignee: Industrial Science & Technology Network, Inc.Inventors: Arthur Jing-Min Yang, Sun-Mou Lai, Roman C.

Publication number: 20070122333Abstract: Amorphous, nanoporous silica gel having an open channel structure may be surface modified at higher loading of surface modifying ligands, e.g., 7.5 mmole per gram, than known nanoporous silica gels. In one embodiment, an amorphous silica gel has a bimodal pore size distribution of pores at about 10 nanometers and at about 10 microns, and a bulk density of about 0.2 to about 0.25 g/ml. Surface modification with functionalized ligand groups, effective for selective adsorption or reaction catalysis, is achieved by gelling silica sol solution to form a wet silica gel, maintaining the gel at a relatively low elevated temperature in a moist state to obtain a wet nanoporous silica gel having a plurality of open channels within the gel structure and silanol groups on the surface and reacting the surface silanol groups with the ligand group to introduce the functionalized group. The surface modifying reaction may be carried out concurrently with the gelling of a silica precursor in an aqueous alcoholic medium.Type: ApplicationFiled: November 20, 2006Publication date: May 31, 2007Applicant: Industrial Science & Technology Network, Inc.Inventor: Arthur Yang

Publication number: 20060207942Abstract: A nanoporous reactive adsorbent incorporates a relatively small number of relatively larger reactant, e.g., metal, enzyme, etc., particles (10) forming a discontinuous or continuous phase interspersed among and surrounded by a continuous phase of smaller adsorbent particles (12) and connected interstitial pores (14) therebetween. The reactive adsorbent can effectively remove inorganic or organic impurities in a liquid by causing the liquid to flow through the adsorbent. For example, silver ions may be adsorbed by the adsorbent particles (12) and reduced to metallic silver by reducing metal, such as irons, as the reactant particles (10). The column can be regenerated by backwashing with the liquid effluent containing, for example, acetic acid.Type: ApplicationFiled: May 16, 2006Publication date: September 21, 2006Applicant: Industrial Science & Technology Network, Inc.Inventors: Arthur Yang, Yuehua Zhang
