    摘要: A continuous method of making dry-stretch microporous membrane battery separators from polypropylene (PP) or polyethylene (PE) or both benefits to the manufacturers in the production efficiency. The precursor-film extrusion in this invention is accomplished by multiple small film-extrusion lines at a compatible line speed with the followed oven processes (annealing and stretching). The overall production process starts continuously from film extrusion to annealing and to stretching. The benefits of the inventive continuous process includes a higher product yield, more effective oven-time usage, no need to handle and manage the intermediate products, less need in labor and machine maintenance, and potentially more stable product quality.The dry-stretch membrane separators made with this inventive continuous method include (1) single-ply PP or PE separators having a thickness ranging from 0.2 mil to 2.0 mil; (2) PP/PE/PP trilayer microporous membrane separators having a thickness ranging from 0.6 mil to 4.0 mil. The PP/PE/PP trilayer can be accomplished in the early extrusion via either co-extrusion or extruding separately and then interposing PE layer between two PP layers, continuously, right before annealing/bonding and stretching process.

    摘要: Continuous seamless cross-plied battery separators are formed by bringing at least two anisotropic with respect to mechanical strength (e.g. uniaxially oriented), microporous plies into adhering face contact such that the uniaxial orientation of one microporous ply is angularly biased relative to the other microporous ply (e.g., between 20.degree. to 90.degree.). This biased relationship between the microporous plies is most preferably achieved by spirally or helically slitting a tubular microporous membrane. The plies are adhered to one another with adhesive and/or by means of heat and pressure. The cross-plied battery separators of this invention exhibit increased puncture strength without significant decrease in permeability. As a result, the battery separators of this invention are especially useful in battery cell configurations whereby the battery separator is sandwiched between anode and cathode sheets to form a composite battery cell structure which is then rolled or folded to be placed in a battery cell can.

    摘要: The present invention discloses a method for fabricating polymeric wavelength filter based on an asymmetric Bragg coupler with single-grating waveguide. The asymmetric waveguide coupler is formed firstly on a negative photo-resist mold. PDMS film is injected into the narrow waveguide of the coupler to act as a protection layer. The gratings pattern is exposed on the alternative waveguide and subsequently transferred to PDMS stamp mold. The PDMS stamp mold is used as a stamp to transfer the gratings pattern of the ABC wavelength filter onto UV cured polymer to form the final ABC filter. Whereby, the fabrication process is reliable and accurate, and can offer great potential for mass production of the ABC filter with single-grating waveguide.
