    摘要: Preferred embodiment stimuli-responsive low solubility copolymer hydrogel compositions of the invention include polymerized N-isopropylacrylamide and water insoluble monomer or oligomer repeating units. The repeating units are arranged within the polymer backbone of the copolymer hydrogel. In a preferred fabrication method, precursors of N-isopropylacrylamide and precursors of the water insoluble monomer of oligomer are solved in a liquid solvent to form a solution in a container. An initiator is added to the solution. Gas is bubbled through the solution, and the container is sealed. The solution is stirred while heating to a polymerization temperature and polymerization is permitted to complete to form the copolymer hydrogel composition.

    摘要: A device including a micro component having an external surface and a permeable nanofiber covering on at least a portion of the external surface of the micro component. A cooled micro component system further includes a droplet spray system for spraying liquid droplets onto the nanofiber covering to cool the micro component. In an example method for cooling a micro component, droplet spray is directed onto a nanofiber covering that covers at least a portion of the micro component. The directing is controlled to permit efficient spreading and evaporation of liquid permeating the nanofiber covering. In example embodiments nanofibers of the permeable nanofiber covering are metalized to provide a rougher surface (e.g., a nano-textured metal layer).

    摘要: The present invention relates to an electrospinning device. The electrospinning device may apply the force of a supersonic flow acting at a predetermined angle with respect to an electrostatic force on a fiber discharged from an electrospinning nozzle to cause shearing stress on the fiber, thereby providing fibers having a very small diameter and collecting fibers having a finer diameter. Also, the electrospinning device may collect finer and more uniform fibers by adjusting the relative positions of the electrospinning nozzle for discharging the fiber and a gas spray nozzle for spraying a gas.

    摘要: A method for removing a liquid from a gas, comprises passing the gas and the liquid through a network of fibers containing at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber, thereby permitting droplets of the liquid to be captured by the at least one fiber, and wherein the temperature gradient causes migration of the droplets. A method of preventing the fouling of a coalescence filter is also disclosed. The method comprises inducing a temperature gradient along at least a portion of a length of at least one fiber within the filter, wherein the temperature gradient causes migration of liquid droplets captured by the fiber. A coalescence filter medium comprising at least one fiber in which a temperature gradient has been induced along at least a portion of the length of the fiber is also provided.
