  • Patent number: 9347928
    Abstract: A method and composition is described for controlling the growth of fouling materials, such as scale, in aqueous systems using a tagged (fluorescent) polymer. The tagged polymer can be a fluorescent polymer which has at least one fluorescent monomeric unit derived from a fluorophore which has at least one terminal end comprising an olefinic group. The method of controlling the growth of at least one fouling material in an aqueous system can include the steps of adding the tagged polymer to the aqueous system to be treated, fluorometrically monitoring the concentration of the tagged polymer, and adjusting, as needed, the concentration of the tagged polymer and proportionally used water treatment compound or compounds effective to control the growth of at least one fouling material. The adjustment of pH before determination of the fluorescence signal can be employed to increase sensitivity of the fluorophore and minimize background interference.

  • Publication number: 20140242623
    Abstract: We disclose methods and compositions for preparation of stimuli-responsive plastics that are capable of responding to chemical and/or physical signals in their environment. In one embodiment the plastics consist of patterned mixtures of poly(phthalaldehyde) polymers in which each polymer contains a different end-capping group (also called a “trigger”), responsive to a different signal. Other embodiments use different polymers and different triggers. The plastics may be homogeneous in composition, but each polymer within the plastic is capable of responding to a different signal and depolymerizing once this signal reacts with the trigger. This process of depolymerization enables the plastic to alter its physical features non-linearly to external signals: i.e., the degree of change in physical form is much larger than the intensity of the initial signal.

  • Patent number: 8720677
    Abstract: Stimuli-responsive highly absorbent superabsorbent polymers (SAPs) are used to harness water to augment water supply and solve water crisis. Rain water, dew or sea water is harnessed in fabric-based sachets or bags partially filled with the polymers. The hydrated polymers are used to store water in warehouses for an extended period of time and the invention may obviate the need to construct controversial huge dams and canals or drill wells. The stored water in superabsorbent polymers is released at the point of use by any stimulus which may be light-induced, electrical, thermal or chemical treatment. SAPs with 2000 g/g of absorbency can yield 99.95% pure water in solid/gel form. An ultra SAP with absorbency of 10,000 g/g of the polymer could hold 10 billion cu·m. of water in one million tonnes of the polymer. This is more than the capacity of a typical large dam over a river.

  • Patent number: 8511464
    Abstract: Stimuli-responsive highly absorbent superabsorbent polymers (SAPs) are used to harness water to augment water supply and solve water crisis. Rain water is harnessed in fabric-based sachets or bags partially filled with the polymers. The hydrated polymers are used to store water in warehouses for an extended period of time and the invention may obviate the need to construct controversial huge dams and canals or drill wells. The stored water in superabsorbent polymers is released at the point of use by any stimulus which may be light-induced, electrical, thermal or chemical treatment. SAPs with 2000 g/g of absorbency can yield 99.95% pure water in solid/gel form. An ultra SAP with absorbency of 10,000 g/g of the polymer could hold 10 billion cu.m. of water in one million tonnes of the polymer. This is more than the storage capacity of a typical large dam over a river.
