Phosphonated PBI fiber

A fiber is made with a polybenzimidazole (PBI) polymer with a phosphoric acid pick-up (APU) in the range of 1-25% (PBI-p fiber). The PBI-p fiber may have a LOI ?50% and/or an initial thermal decomposition temperature in air of ?555? C. A method of making a phosphonated polybenzimidazole fiber comprises the steps of: spinning an untreated PBI resin into a PBI fiber; treating the PBI fiber with phosphoric acid, and thereby obtaining a PBI fiber with 1-25 wt. % phosphoric acid APU.

20190322826 · 2019-10-24 ·

Provided is a method for preparing a carbon nanotube/polymer composite material, including: coating a nano-silicon oxide film on the surface of a porous polymer by vacuum coating; depositing a metal catalyst nano-film on the nano-silicon oxide film by vacuum sputtering; growing a carbon nanotube array in situ on the surface of the porous polymer by plasma enhanced chemical vapor deposition to obtain a carbon nanotube/polymer porous material; and impregnating the carbon nanotube/polymer porous material with a polymer and curing to obtain the carbon nanotube/polymer composite material. By using a heat-resistant polymer having a high heat-resistant temperature and a PECVD technique, a carbon nanotube array directly grows in situ on the surface of a polymer at a low temperature, which thereby overcomes the defects of the composites previously prepared, in which carbon nanotubes are difficult to be homogeneously dispersed and the interfacial bonding force in the composites is weak.

20190231653 · 2019-08-01 ·

A skin care fabric for medical, pharmaceutical or cosmetic use includes at least 80% by weight of microfibers that are a mixture of polyamide and polyester and have a diameter of less than 50 microns. Each microfiber is split to produce fine fibers closely packed in a parallel structure having a capillary effect and an abrasive effect. The fabric has a surface weight of less than 180 g/m.sup.2 and is loaded with medical, pharmaceutical or cosmetic active agents. The skin care fabric includes a warp-knitted fabric having a first surface and a second surface opposite the first surface, which is mechanically roughened and cut to become fluffy and yet short-haired and compact and resulting in a further surface enlargement of the fabric structure and a water absorbency of at least four times the surface weight of the fabric.
