  • Patent number: 10844545
    Abstract: A method for wet production of a superabsorbent material. The method comprises forming an aqueous saline solution with a concentration of 0.01-4.5 N of ionic salt and a pH from 0 to 6.0 or from 8.0 to 14.0 by the addition of a strong acid or strong base; dispersing in the saline solution a water superabsorbent polymer (SAP); creating a first web by stratification and deposition under vacuum suction onto a mesh screen belt deposition section of the SAP dispersion; washing the web with a basic solution (or with an acidic solution) up to the desired level of neutralization of the acidity (or basicity) for SAP dispersions in acidic (or basic) saline solutions; washing the web with water and suction; and drying the web. The relationship between pH and salt concentration causes a water absorption in the SAP equal to or less than about 30.00 gH2O/gSAP.

  • Patent number: 9624622
    Abstract: Disclosed are carpet products comprising at least one flexible substrate and at least one coating and/or adhesive layer associated with the at least one flexible substrate. The coating and/or adhesive layer is formed from an aqueous composition comprising: A) an emulsifier-stabilized vinyl acetate/ethylene (VAE) emulsion copolymer dispersion and B) at least one particulate filler material selected from particulate inorganic compounds and particulate plastic material. The vinyl acetate/ethylene copolymer in the copolymer dispersion has a selected ethylene content or glass transition temperature. It is also preferably substantially free of cross-linkable co-monomer moieties which generate formaldehyde upon curing and preferably has a particle size, dw, ranging from about 50 to about 500 nm. The carpet product is substantially free of polyvinyl chloride and bitumen and exhibits a Class B1 flame-retardancy in accordance with DIN 4102-14, corresponding to a critical heat flux of ?about 4.5 kW/m2.

  • Patent number: 9599564
    Abstract: A quantum dot-polymer nanocomposite sensor array for chemical vapor sensing includes plurality of sensors respectively formed by different nanocomposite films. Each nanocomposite film is formed by a plurality of QDs and a polymer solution made from a polymer and a corresponding solvent. The plurality of sensors are disposed on a substrate for impingement by an excitation light source. Fluorescence emission intensity of the sensors is measured for a preselected duration of time and then the sensors are placed into contact with a chemical vapor. The changes in fluorescence emission intensity for all sensors are detected over time and the combined changes in fluorescence are compared to establish a unique combined response for each target chemical vapor. Using this unique combined response from a sensor array, target chemical vapor can be detected, classified, and identified.
