Abstract: Amorphous silica-alumina support materials are provided that can serve as supports for polyamines. The silica-alumina support materials have a combination of properties that unexpectedly allow supported polyamines to retain an increased or maximized amount of CO2 sorption capacity after incorporation of substantial amounts of the polyamine on the support material. This combination of properties can include having a high pore volume, a high ratio of mesopore volume to micropore volume, and a sufficiently high acidity. The ability to allow supported amine sorbents to retain additional CO2 sorption capacity is unexpected. Additionally, the relationship between having sufficiently high acidity and providing improved sorption capacity for a supported amine material is unexpected.

Abstract: Crystalline support materials are provided that can serve as supports for polyamines. The support materials have a combination of properties that unexpectedly allows supported polyamines to retain an increased or maximized amount of CO2 sorption capacity after incorporation of substantial amounts of the polyamine on the support material. This combination of properties can include having a high pore volume, a high ratio of mesopore volume to micropore volume, and a sufficiently high acidity. The ability to allow supported amine sorbents to retain additional CO2 sorption capacity is unexpected. Conventionally, even when high pore volume support materials are used to support an amine sorbent, only a limited amount of the amine sorbent can be supported on the support material before substantial losses of sorbent capacity occur relative to the amount of amine sorbent.

Abstract: Traditionally, sol-gel silicates have been reported as being high temperature processable at 400 C to give reasonably dense films that showed good leakage current densities (<5×10?8 A/cm2). Recently we have discovered that we are able to prepare films from particular combinations of sol-gel silicate precursors that cure at 135° C. to 250° C. and give good leakage current density values (9×10?9 A/cm2 to 1×10?10 A/cm2) as well, despite the decrease in processing temperatures. These are some of the first examples of silicates being cured at lower temperatures where the leakage current density is sufficient low to be used as low temperature processed or solution processable or printable gate dielectrics for flexible or lightweight thin film transistors. These formulations may also be used in the planarization of stainless steel foils for thin film transistors and other electronic devices.
