摘要:
A functionalized fiber. The functionalized fiber includes a fiber strand and silica nanoparticles at least partially encapsulating the fiber strand. The silica nanoparticles are synthesized by hydrolyzing a tetramethyl orthosilicate in hydrochloric acid to form silicic acid monomers. The silicic acid monomers are diluted in acetone and irradiated for a time that is less than 90 seconds with an energy source configured to generate microwave frequency energy to polymerize the silicic acid monomers into the silica nanoparticles.

摘要:
Porphyrin-modified antimicrobial peptides as described here may be used as indicators of the presence of microbial targets. Their application may be as (for example) (1) fluorescent indicators in a microarray format, (2) fluorescence or absorbance based indicators in traditional solution based applications, or (3) reflectance based indicators for use in reagent-less detection platforms.

摘要:
A super-hydrophobic fiber of the present disclosure includes: a nano-needle fiber having a surface including needle-shaped nano structures; and a coating layer disposed on the surface including the nano structures, and containing a hydrophobic material. The fiber has no aging effect, and thus, is excellent in durability, and has such a large contact angle and such as small sliding angle that the fiber may not be wet with water. A method for fabricating the super-hydrophobic fiber includes: a preparation step of preparing a pre-treating fiber; an etching step of etching a surface and an inner portion of the pre-treating fiber to fabricate a nano-needle fiber having a surface on which needle-shaped nano structures are formed; and a coating step of forming a coating layer containing a hydrophobic material, and enables mass production and is performed by simple processes.Further, an article including the super-hydrophobic fiber is an article in which no liquid drop is absorbed, scarcely adsorbs a contaminant, needs not be dried, and thus, may be widely applied even to recreational articles.

As described herein, an abrasion resistant nonwoven fabric includes fibers having an external surface covered with a treatment selected from the group consisting of organosilicone compounds applied by plasma treatment in inert gas without the presence of oxygen and acrylic monomers having a Tg greater than or equal to 20 degrees C. applied onto the nonwoven fabric and subsequently surface grafted and crosslinked via exposure to plasma glow discharge or e-beam without the presence of oxygen. The treated fabrics demonstrate improved abrasion resistance over untreated fabrics.
摘要:
Method for producing an oxidized PAN fiber (OPF) wherein a PAN fiber is subjected to an oxidation process in which reactive oxidizing species are maintained in close enough proximity to the PAN fiber during the oxidation process such that a core of the PAN fiber is converted to a crosslinked thermoset morphology before an oxidized shell of the PAN fiber becomes thick enough to substantially inhibit penetration of the reactive oxidizing species into the core. The resulting OPF possesses a density greater than 1.35 g/cm3 and a substantially homogeneous crosslinked thermoset morphology along a radial dimension of the oxidized PAN fiber. Flame-retarded materials containing the resulting OPF, as well as methods for producing such flame-retarded materials, are also described.
