摘要： A process is disclosed for obtaining olefin-polar comonomer resin in fibrous form. According to the invention, an olefin-polar comonomer resin such as an ethylene-vinyl acetate copolymer is vigorously agitated in molten form in water in the presence of a resin dispersion-forming amount of an alkali metal soap such as sodium stearate and a fiber-forming amount of base such as sodium hydroxide at a temperature below the degradation temperature of the resin to provide a dispersion of said resin in which a substantial number of the individual resin particles are in the form of a fiber possessing an average length of from about 50 to about 2500 microns and an average length to diameter ratio of at least about 3:1. Following cooling of the dispersion to below the solidification point of the resin, the resin fiber may be recovered employing known and conventional means, e.g., filtration, centrifugation, etc.

摘要： Polymeric fibrids and paper-like structures produced therefrom are disclosed. These fibrids are produced by preparing an aqueous solution of a film forming polymer, injecting the solution into a liquid precipitating medium miscible with water but in which the polymer is insoluble, and providing sufficient shear to directly and rapidly precipitate the polymer to fibrid morphology. The fibrids, which are desirably first treated to render them more hydrophobic, may be formed into a web and dried utilizing conventional paper-making techniques to obtain the paper-like structures of the invention.

摘要： Polymeric fibers are produced from a polymer-solvent solution without mechanical agitation means by supplying a polymer solution in a solvent to a radial-symmetrical mixing chamber and causing a rotary flow therein which subjects the polymer to shearing forces while, at the same time, adjusting the temperature of the polymer-solvent mix to just below the precipitation temperature of the polymer. Under these conditions a polymeric fiber precipitates which, after separation from the solvent, is useful in the preparation of paper and textile products.

摘要： The present invention relates to a preparation method of para-aramid nanofibers, and belongs to the technical field of novel polymer materials. The para-aramid nanofibers prepared in the present invention have a diameter of 10-100 nm, and a length of hundreds of microns. The preparation method includes: adding a certain amount of surfactant in a PPTA low-temperature polymerization process, and controlling aggregation of PPTA molecules along with growth of a PPTA molecule chain, thereby preparing the para-aramid fibers with a uniform size and an adjustable nano-scale diameter under assistance of other means (e.g., a coagulator and high-speed shearing dispersion). The present invention is short in production process and simple in equipment, can realize stable batch production to meet needs of large-scale production of the para-aramid nanofibers, has wide application prospects and can be applied to preparing a lithium-ion battery separator, a high-performance composite material and the like.

摘要： The invention relates to a continuous, scalable and parallelizable method for preparing strong and stiff fibers (filaments) or films. The fiber or film is prepared by utilizing hydrodynamically induced alignment of the constituents of a dispersion in combination with surface-charge controlled gel transition to produce fibers with a high degree of alignment of the constituents (polymer(s), fibrils etc). The invention also relates to the fibers or films so formed.

摘要： An apparatus for producing a body, preferably a nano-body, through the introduction of a body-forming fluid into a dispersion medium. The apparatus includes: a fluid housing configured to house a dispersion medium; at least two separated flow paths along which the dispersion medium flows in a laminar flow, at least two of the separated flow paths converging at a flow-merge location; a fluid flow arrangement which, in use, causes the dispersion medium to flow along each flow path to the flow-merge location; at least one fluid introduction arrangement located at or proximate the flow-merge location configured, in use, to feed the body-forming fluid into the dispersion medium; and a flow constriction arrangement proximate to or following the flow-merge location, which in use, constricts and accelerates the dispersion medium flow proximate to and/or following the flow-merge location.
