    Abstract: A method of making a porous membrane is disclosed. One such method optionally includes: forming a plurality of pillars in an array form over a substrate; and forming a layer with a mixture of a porous material precursor and a surfactant over the substrate. The method optionally includes removing the pillars to leave cavities in the layer; filling the cavities in the layer with a cavity filler; and removing the surfactant from the layer. The porous membrane can be used as, for example, a sieve for separating molecules from a chemical reaction.

  • Publication number: 20100044302
    Abstract: Hydrophilic membrane particularly suited for blotting applications, preferably Western blotting. A pre-wet hydrophobic membrane substrate, preferably made of PVDF, is contacted with a monomer solution and subjected to a UV-initiated free radical polymerization step to render the substrate permanently hydrophilic. The resulting membrane exhibits low background fluorescence, high protein binding, excellent retention of protein sample spot morphology, and extended dynamic range (high signal-to-noise ratio, enhanced sample detectability). The membrane demonstrates comparable or higher performance in Western blotting applications than conventional nitrocellulose Western blotting membranes, particularly for protein detection at low sample concentrations, and is directly water-wettable, eliminating the need for an alcohol pre-wet step prior to use.

This invention is also curable oligomers and polymers and highly cross-linked polymers made with such monomers. Moreover, this invention is a method of making porous films by combining such monomers or their oligomers with a porogen, curing the polymer and removing the porogen.

  • Publication number: 20090304920
    Abstract: Methods for the selective deposition of materials within a porous substrate. The methods use the passivating effects of masking precursors applied to the porous substrate. A portion of a pore surface within the substrate is masked by exposing the substrate to one or more masking precursors. The depth of the pore surface that is masked is controllable by regulating the exposure of the substrate to the masking precursor. Application of the masking precursor prevents adsorption of one or more subsequently applied metal precursors about a portion of the pore surface coated by the masking precursor. Less than an entirety of the unmasked pore surface is coated by the metal precursor, forming a metal stripe on a portion of the pore surface. The depth of the metal stripe is controllable by regulating exposure of the porous substrate to the metal precursor. Subsequent exposure of the substrate to a saturating water application oxidizes the deposited precursors.

  • Publication number: 20090232982
    Abstract: A coating liquid containing a polymer and a hydrophobic solvent is applied to a support to form a coating film. Water vapor is condensed from ambient air on a surface of the coating film. A hydrophobic solvent is evaporated until a content rate of the solvent in the coating film reaches 50 wt %. The coating film is caused to contact with liquid water. The hydrophobic solvent contained in the coating film is moved from the coating film to the water. The water and the solvent are evaporated from the coating film. Thus, a porous film having a plurality of pores is produced. It is unnecessary to adjust a surface temperature of the coating film and a dew point of the gas around the coating film precisely. It becomes possible to evaporate the hydrophobic solvent contained in the coating film rapidly.

    Abstract: This invention provides methods for preparing mixtures of styrene and maleic anhydride co-monomer, applying that mixture to the surface of a solid porous substance like wood, allowing the mixture to penetrate the surface zone of the material such as wood and causing it to quickly cure in the surface zone of the material. The keys are the low viscosity of the mixture that causes it to penetrate quickly and well, and its reactivity that causes it to cure before it either evaporates or becomes too dispersed within the material. The polymer reinforcement and hardening is therefore effectively restricted to the surface zone or shell. This produces a reinforced, hardened, protective shell around the porous material.

  • Publication number: 20080268227
    Abstract: The present invention relates to a complex polishing pad and method for making the same. The method of the invention comprises the steps of: (a) providing a buffer layer, the buffer layer being continuous-porous material and having a surface; (b) flattening the surface of the buffer layer to form a flattened surface; and (c) disposing a polishing layer on the flattened surface so as to form the complex polishing pad, wherein the polishing layer is used to polish a polishing workpiece. Whereby, the complex polishing pad of the invention has a better flatness, and the buffer layer and the polishing layer have a stronger combination.
