A preparation method for an yttrium aluminum garnet continuous fiber. The method prepares a spinnable precursor sol by utilizing an Al.sub.13 colloidal particles contained alumina sol, γ-AlOOH nano-dispersion, yttria sol, glacial acetic acid and polyvinylpyrrolidone, then prepares a gel continuous fiber by adopting a dry spinning technique, and carries out a heat treatment to obtain the yttrium aluminum garnet continuous fiber.

Compositions especially suitable for forming fibers and films having good elasticity and relatively high modulus are disclosed. Surprisingly, compositions including a styrenic block copolymer having a relatively high melt flow rate, and a detackifier, and optionally, but preferably in some embodiments a polyolefin (co)polymer, and/or polystyrene polymer, and/or a softener have good draw down performance and are processable into fibers having low tack, relatively high modulus and tensile strength. The fibers produced from the composition can be processed easily and are useful to manufacture articles such as fabrics, both woven and non-woven, webs, threads, and yarns. In various embodiments, unique fiber structures are produced having low tack and desirable elasticity.

The present disclosure provides a preparation method of a plasma-treated nanofiber-based hydrogen gas sensing material, including the following steps: (1) stirring a mixed solution of absolute ethanol, polyvinyl pyrrolidone (PVP), N, N-dimethylformamide, SnCl.sub.2.H.sub.2O, and Zn(CH.sub.3COO).sub.2.2H.sub.2O uniformly on a constant-temperature magnetic stirrer to obtain a spinning solution; (2) electrospinning the spinning solution and depositing on an aluminum foil to obtain a spinning fiber; (3) annealing the spinning fiber in a muffle furnace to obtain a hydrogen gas sensing material sample; and (4) subjecting the hydrogen gas sensing material sample to a vacuum argon plasma treatment with a Hall ion source to obtain the nanofiber-based hydrogen gas sensing material. In the method, nanofibers are prepared by electrospinning and subjected to the vacuum argon plasma treatment through the Hall ion source. The prepared sensing material has an extremely large specific surface area, and gas-sensing properties of rapid response and high sensitivity to hydrogen gas.
