摘要： Charged polymeric webs, such as electret webs, include a thermoplastic resin and a charge-enhancing additive. The additives are substituted heterocyclic thiolate salts. The heterocyclic thiolate salt has 2 nitrogen groups and a third group that may be an NH, N—NH2, O, or S group. The substituent group is an aromatic or heterocyclic aromatic group. The electret webs may be a non-woven fibrous web or a film. The electret webs are suitable for use as filter media.

摘要： A method for making a copolymer-wrapped nanotube coaxial fiber. The method includes supplying a first dope to a spinning nozzle; supplying a second dope to the spinning nozzle; spinning the first and second dopes as a coaxial fiber into a first wet bath; and placing the coaxial fiber into a second wet bath, which is different from the first bath. The coaxial fiber has a core including parts of the first dope and a sheath including parts of the second dope. Solvent molecules of the second wet bath penetrate the sheath and remove an acid from the core.

摘要： A textile graphene component thermal fiber, or filament yarn, is able to be integrated into a textile, for example performance knits, woven and non-woven garments and linens, in order to conduct absorb or emit heat in order to regulate the body temperature for a user. The textile graphene component thermal fiber is able to absorb thermal energy and optimally conduct the thermal energy for extended periods of time. The textile graphene component thermal fiber includes a quantity of polymers, a first quantity of graphene, and a second quantity of graphene The quantity of polymers and the first quantity of graphene are mixed into a polymeric sheath. The second quantity of graphene and the quantity of thermally conductive substances are mixed into a thermal-conducting core. The polymeric sheath encloses the thermal conducting core in order to form the textile bi-component thermal fiber.
