A method for modifying the wettability of a surface of an object can comprise forming on the surface of the object one or more arrays of nanofibers, wherein the one or more arrays of nanofibers includes nanofibers spaced along an X-axis and a Y-axis at the same or different intervals along either axis, the one or more arrays of nanofibers is integral with the object, and the nanofibers all have a base portion that is substantially normal to the surface. The intervals, diameter, and length of the nanofibers of the one or more arrays of nanofibers are selected so that the wettability of the surface for one or more predetermined liquids is increased or decreased relative to the wettability of the surface in the absence of the array of nanofibers.

Provided are a filter medium for a filter, which makes it possible to obtain a filter high in collection efficiency, low in pressure loss and long in filter lifetime, a method for producing the same, and a filter using the filter medium for a filter. A filter medium for a filter is used as a constituent member of a filter and composed of a wet type nonwoven fabric, wherein the filter medium for a filter has a multilayer structure of two or more layers, and there is no interface between the above-mentioned two layers.

A waved meltblown fiber web of the present invention relates to a fiber web prepared by a meltblown method and is characterized by a preparation method in which a meltblown microfiber comes in contact with collection portions having different surface velocities so as to be collected. The waved meltblown fiber web of the present invention is characterized in that: a part of meltblown microfibers reaches a low velocity collection portion so as to be horizontally layered, thereby forming a horizontal fiber layer (10); another part of the meltblown microfibers reaches a high velocity collection portion of which the surface velocity is greater that of the low velocity collection portion so as to form a serpentine vertical fiber layer (20); and the upper end of the vertical fiber layer (20) becomes entangled so as to form a wave shaped wave layer (30) forming the uppermost portion of the fiber web.

A method of synthesizing mechanically resilient titanium carbide (TiC) nanofibrous felts comprising continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix, comprising: (a) electrospinning a spin dope for making precursor nanofibers with diameters less than 0.5 J.Lm; (b) overlaying the nanofibers to produce a nano-fibrous mat (felt); and then (c) heating the nano-felts first at a low temperature, and then at a high temperature for making electrospun continuous nanofibers or nano-ribbons with TiC crystallites embedded in carbon matrix; and (d) chlorinating the above electrospun nano-felts at an elevated temperature to remove titanium for producing carbide derived carbon (CDC) nano-fibrous felt with high specific surface areas.
