  • Patent number: 9212238
    Abstract: Provided is an electronic microparticle, including a first copolymer copolymerized from a first monomer and a second monomer or a second copolymer copolymerized from the first monomer, the second monomer and a third monomer. The first monomer includes an alkenyl group and excludes a sulfonic group, a carboxylic group, a hydroxyl group and an amino group. The second monomer includes an alkenyl group and further includes a sulfonic group or a carboxylic group. The third monomer includes an alkenyl group and further includes a hydroxyl group or an amino group. Either the first monomer or the second monomer has a ratio of the repeating units of the first monomer to the repeating units of the second monomer between about 200:1 and 20:1. In addition, an addition agent and a filtering membrane which include the electronic microparticle illustrated above are provided.
    Type: Grant

  • Publication number: 20130168312
    Abstract: The disclosure discloses a filtration material for desalination, including: a support layer; a nanofiber layer formed on the support layer; a hydrophobic layer formed on the nanofiber layer; and a hydrophilic layer formed on the hydrophobic layer. The nanofiber layer includes ionic polymer, polyvinyl alcohol (PVA), polyacrylonitrile, (PAN), polyethersulfone (PES) or polyvinglidene fluoride (PVDF). The hydrophobic layer includes polypropylene (PP), polyvinglidene fluoride (PVDF), poly-dimethylsiloxane (PDMS) or epoxy.

  • Patent number: 8258393
    Abstract: A thermoelectric device is provided. The thermoelectric device includes a P-type thermoelectric component, an N-type thermoelectric component, and an electrically conductive layer. Each of the P-type thermoelectric component and the N-type thermoelectric component includes a substrate and a nanowire structure. The conductive layer connects the P-type thermoelectric component set with the N-type thermoelectric component set. The thermoelectric device is adapted for recycling heat generated by the heat source, and for effectively converting the heat into electrical energy.
