The present teachings contemplate forming a reformable epoxy resin material into a monofilament having a denier of from about 50 to about 5000 and a glass transition temperature of less than about 200° C.; loading one or more monofilaments onto a spool; co-weaving the one or more monofilaments with a reinforcing fiber to form a woven material, the reinforcing fiber having a glass transition temperature of greater than 200° C.; heating the woven material to form a composite to a temperature so that only the one or more monofilaments soften but the reinforcing fiber does not.

The invention relates to a polymer fibre with improved dispersibility, a method for producing said fibre and the use of said fibre. The polymer fibre according to the invention comprises at least one synthetic polymer and 0.1 and 20 wt. % of a silicone. The polymer forming the fibre forms a solid dispersion medium at room temperature (25° C.) for the silicone present in solid form also at room temperature (25° C.) which forms the more disperse phase. The polymer fibre according to the invention possesses an improved dispersibility and is therefore suitable for producing aqueous suspensions which are used, for example, in the formation of textile fabrics, e.g. nonwovens.

A method of forming a polymer-metal nanocomposite (PMNC) material with a substantially uniform dispersion of metal particles includes forming a composite solid preform by mixing a blend of micrometer-sized metal particles and polymer particles and subjecting the mixture to compression followed by sintering. The composite solid preform is drawn through a heated zone to form a reduced size fiber. The reduced size fiber is cut into segments and a next preform is formed using the bundle of the segments. The next preform is then drawn through the heated zone to form yet another reduced size fiber. This reduced size fiber may undergo one or more stack-and-draw operations to yield a final fiber having substantially uniform dispersion of nanometer-sized metal particles therein.

Provided are a composite forward osmosis membrane and a membrane module containing same. The composite forward osmosis membrane reduces salt back-diffusion and has high water-permeability, or is made of readily available materials and can be easily manufactured. Even when used at high pressure, separation between a substrate membrane support layer and an active separation layer does not occur in the composite forward osmosis membrane, and thus the composite forward osmosis membrane exhibits stable high performance.

Embodiments of this invention are directed to substituted polyaniline nanofibers and methods of synthesizing and using the same. The invention is also directed to polyaniline derivatives that can be synthesized without the need for templates or functional dopants by using an initiator as part of a reaction mixture.
