摘要： Described herein are nanofibers and methods for making nanofibers that have a plurality of pores. The pores have of any suitable size or shape. In some embodiments the pores are “mesopores”, having a diameter between 2 and 50 nm. In some embodiments, the pores are “ordered”, meaning that they have a substantially uniform shape, a substantially uniform size and/or are distributed substantially uniformly through the nanofiber. Ordering of the pores results in a high surface area and/or high specific surface area. Ordered pores, without limitation, result in a nanofiber that is substantially flexible and/or non-brittle. The nanofibers and methods for making nanofibers may be used, without limitation, in batteries, capacitors, electrodes, solar cells, catalysts, adsorbers, filters, membranes, sensors, fabrics and/or tissue regeneration matrixes.

摘要： This invention pertains to surfactant-templated nanometer-scale porosity of a silica precursor solution and forming a mesoporous material by first forming the silica precursor solution into a preform having a high surface area to volume ratio, then rapid drying or evaporating a solvent from the silica precursor solution. The mesoporous material may be in any geometric form, but is preferably in the form of a film, fiber, powder or combinations thereof. The rapid drying or evaporation of solvent from the solution is accomplished by layer thinning, for example spin casting, liquid drawing, and liquid spraying respectively. Production of a film is by layer thinning, wherein a layer of the silica precursor solution is formed on a surface followed by removal of an amount of the silica precursor solution and leaving a geometrically thinner layer of the silica precursor solution from which the solvent quickly escapes via evaporation. Layer thinning may be by any method including but not limited to squeegeeing and/or spin casting. In powder formation by spray drying, the same conditions of fast drying exists as in spin-casting (as well as in fiber spinning) because of the high surface-area to volume ratio of the product. When a powder is produced by liquid spraying, the particles or micro-bubbles within the powder are hollow spheres with walls composed of mesoporous silica. Mesoporous fiber formation starts with a similar silica precursor solution but with an added pre-polymer making a pituitous mixture that is drawn into a thin strand from which solvent is evaporated leaving the mesoporous fiber(s).

摘要： Self-repairing, fiber reinforced matrix materials include a matrix material including inorganic as well as organic matrices. Disposed within the matrix are hollow fibers having a selectively releasable modifying agent contained therein. The hollow fibers may be inorganic or organic and of any desired length, wall thickness or cross-sectional configuration. The modifying agent is selected from materials capable of beneficially modifying the matrix fiber composite after curing. The modifying agents are selectively released into the surrounding matrix in use in response to a predetermined stimulus be it internal or externally applied. The hollow fibers may be closed off or even coated to provide a way to keep the modifying agent in the fibers until the appropriate time for selective release occurs. Self-repair, smart fiber matrix composite materials capable of repairing microcracks, releasing corrosion inhibitors or permeability modifiers are described as preferred embodiments in concrete and polymer based shaped articles.

摘要： This invention pertains to surfactant-templated nanometer-scale porosity of a silica precursor solution and forming a mesoporous material by first forming the silica precursor solution into a preform having a high surface area to volume ratio, then rapid drying or evaporating a solvent from the silica precursor solution. The mesoporous material may be in any geometric form, but is preferably in the form of a film, fiber, powder or combinations thereof. The rapid drying or evaporation of solvent from the solution is accomplished by layer thinning, for example spin casting, liquid drawing, and liquid spraying respectively. Production of a film is by layer thinning, wherein a layer of the silica precursor solution is formed on a surface followed by removal of an amount of the silica precursor solution and leaving a geometrically thinner layer of the silica precursor solution from which the solvent quickly escapes via evaporation. Layer thinning may be by any method including but not limited to squeegeeing and/or spin casting. In powder formation by spray drying, the same conditions of fast drying exists as in spin-casting (as well as in fiber spinning) because of the high surface-area to volume ratio of the product. When a powder is produced by liquid spraying, the particles or micro-bubbles within the powder are hollow spheres with walls composed of mesoporous silica. Mesoporous fiber formation starts with a similar silica precursor solution but with an added pre-polymer making a pituitous mixture that is drawn into a thin strand from which solvent is evaporated leaving the mesoporous fiber(s).
摘要翻译：本发明涉及二氧化硅前体溶液的表面活性剂模板纳米级孔隙率，并通过首先将二氧化硅前体溶液形成具有高表面积与体积比的预成型体形成介孔材料，然后快速干燥或蒸发二氧化硅溶剂前体溶液。介孔材料可以是任何几何形式，但优选为薄膜，纤维，粉末或其组合的形式。溶剂从溶液中快速干燥或蒸发即可通过层间稀化来实现，例如旋转浇铸，液体拉伸和液体喷涂。膜的制备是通过薄层变薄，其中在表面上形成二氧化硅前体溶液层，然后除去一定量的二氧化硅前体溶液，并留下几何较薄的二氧化硅前体溶液层，溶剂快速从其中逸出通过蒸发。层薄化可以通过任何方法，包括但不限于刮涂和/或旋转浇铸。在通过喷雾干燥形成粉末的过程中，由于产品的表面积与体积比高，因此在旋转铸造（以及纤维纺丝）中存在相同的快干条件。当通过液体喷雾产生粉末时，粉末中的颗粒或微小气泡是具有由介孔二氧化硅组成的壁的中空球体。中孔纤维形成从类似的二氧化硅前体溶液开始，但是加入预聚物制成垂直的混合物，其被拉入薄的链中，从该溶液中蒸发掉溶剂，留下介孔纤维。
