The present invention relates in general to a method and variations thereof for making an article, such as cloth, water repellent and/or water resistant (i.e., hydrophobic) as well as oil repellent (i.e., oleophobic). In particular, the method involves the process of providing a thin-layer polymer coating on the article thereby rendering the article water repellent and/or water resistant. Articles made according to the method of the present invention are also disclosed and claimed herein as are the treated articles' use.

Hydrophobic and oleophobic material

The present invention relates in general to a method and variations thereof for making an article, such as cloth, water repellent and/or water resistant (i.e. hydrophobic) as well as oil repellent (i.e. oleophobic). In particular, the method involves the process of providing a thin-layer polymer coating on the article thereby rendering the article water repellent and/or water resistant. Articles made according to the method of the present invention are also disclosed and claimed herein as are the treated articles' use.

Method for making an article hydrophobic and oleophobic as well as articles made therefrom and their use

The present invention relates in general to a method and variations thereof for making an article such as cloth water repellent and/or water resistant. In particular, the method involves the process of providing a thin-layer polymer coating on the article thereby rendering the article water repellent and/or water resistant. Articles made according to the method of the present invention are also disclosed and claimed herein.

Method for making an article water resistant and articles made therefrom

A method of forming carbon nanotube-filled composites using miniemulsion polymerization. The carbon nanotubes are preferably single-walled carbon nanotubes. The carbon nanotubes are highly dispersed within and associated with the polymer comprising the composite.

Carbon nanotube-filled composites prepared by in-situ polymerization

A drug delivery system which includes a plurality of microcapsules, each microcapsule containing a plasminogen activator entrapped in a biocompatible, biodegradable, substantially water-soluble polymeric matrix such that the plasminogen activator is releasable therefrom upon exposure of the microcapsules to an aqueous environment, as well as methods for preparing same. Methods of treating a thrombotic condition and reducing the time required for reperfusion of an occluded blood vessel are also described, which include parenterally administering to a mammal a therapeutically effective amount of a pharmaceutical composition which includes a plurality of such microcapsules.

Microencapsulated plasminogen activators

A composition comprising a plurality of microcapsules suitable for parenteral injection into a mammal comprising a plasminogen activator-containing core, and a semi-permeable biocompatible layer surrounding the core permitting controlled release of at least a portion of the plasminogen activator. A method of reducing the time required for reperfusion of an artery containing a thrombus and a method to reduce the standard dosage requirement of a plasminogen activator in a mammal comprising intravenous injection of a composition comprising a plurality of microcapsules comprising a plasminogen activator core surrounded by a controlled release semi-permeable layer.

Method and composition for the treatment of thrombosis in a mammal

A method for producing polymeric films in which a substrate surface is contacted with a surfactant solution, comprising a liquid in which at least a first surfactant is dissolved, so that an interface is formed between the substrate surface and the surfactant solution, under conditions which promote the assembly at such interface of surfactant molecules, such assembled molecules defining a surfactant template for the film to be produced. After monomer molecules have become concentrated within the surfactant template, polymerization is effected to produce an ultrathin polymeric film dimensionally determined by the surfactant template. Such film is characterized by a polymer network disposed within a surfactant template. The method of the present invention may be used to coat the surface of an object, such as an object which is porous or has non-planar surfaces, or may be used to coat particulate matter.

Producing polymeric films from a surfactant template

A method for producing polymeric films in which a substrate surface is contacted with a surfactant solution, comprising a liquid in which at least a first surfactant is dissolved, so that an itnerface is formed between the substrate surface and the surfactant solution, under conditions which promote the assembly at such interface of surfactant molecules, such assembled molecules defining a surfactant template for the film to be produced. After monomer molecules have become concentrated within the surfactant template, polymerization is effected to produce an ultrathin polymeric film dimensionally determined by the surfactant template. Such film is characterized by a polymer network disposed within a surfactant template. The method of the present invention may be used to coat the surface of an object, such as an object which is porous or has non-planar surfaces, or may be used to coat particulate matter.
