摘要： A method for preparing an ultrashort electrospun polyimide nanofiber, comprising: preparing a polyamide acid solution; forming a polyamide acid fiber felt by electrospinning; cutting the polyamide acid fiber felt into strips; forming a highly oriented polyimide nanofiber bundle by hot stretching and cutting the polyimide fiber to form an ultra-short polyimide nanofiber, wherein the polyamide acid fiber felt is cut into strips with a width of 3 - 8 cm; and the ultra-short polyimide nanofiber formed by cutting is 0.1 - 2.00 mm long. The obtained ultra-short nanofibers have uniform length distributions, good dispersibilities, and potential uses in preparing carbon fiber composite materials and flexible honeycomb materials.

摘要： Provided is a flame-retardant fiber having improved light resistance and/or colorability. The flame-retardant fiber is a fiber including a fiber-forming polymer. The fiber-forming polymer contains a polymer blend comprising a polyetherimide polymer (A) and a thermoplastic polymer (B) having a glass transition temperature lower than that of the polymer (A); and the fiber-forming polymer further contains a functional additive (C) that provides light resistance, colorability, or both of light resistance and colorability. The mass ratio (A)/(B) of the polymer (A) to the polymer (B) is from 50/50 to 90/10, and the content of the functional additive (C) is from 0.5 to 10% by mass relative to 100% by mass of the total mass (A + B + C) of the polymer (A), the thermoplastic polymer (B), and the functional additive (C).
