摘要： In a method of making a carbon fiber, PAN (poly(acrylonitrile-co methacrylic acid)) is dissolved into a solvent to form a PAN solution. The PAN solution is extruded through a spinneret, thereby generating at least one precursor fiber. The precursor fiber is passed through a cold gelation medium, thereby causing the precursor fiber to gel. The precursor fiber is drawn to a predetermined draw ratio. The precursor fiber is continuously stabilized to form a stabilized fiber. The stabilized fiber is continuously carbonized thereby generating the carbon fiber. The carbon fiber is wound onto a spool. A carbon fiber has a fiber tensile strength in a range of 5.5 GPa to 5.83 GPa. The carbon fiber has a fiber tensile modulus in a range of 350 GPa to 375 GPa. The carbon fiber also has an effective diameter in a range of 5.1 μm to 5.2 μm.

摘要： In a method of making a material, a bismaleimide system is heated to generate a bismaleimide liquid (110). The bismaleimide liquid is degassed (114) to generate a degassed bismaleimide liquid. At least one of high speed shear mixing and probe sonication is performed to the degassed bismaleimide liquid to generate a highly mixed bismaleimide liquid phase (112). The highly mixed bismaleimide liquid phase is cured (116). A bismaleimide product is made by heating a three component bismaleimide system to generate a bismaleimide liquid, which is degassed in a 30 mbar vacuum until no new visually perceptible bubbles are detected. The degassed liquid is high speed shear mixed at a speed of 3500 RPM for 10 minutes to generate a highly mixed bismaleimide liquid phase, which is cured to make the bismaleimide product. A substance includes cured bismaleimide having an impact strength in a range of 56 kJ/m2 to 82 kJ/m2.

摘要： Carbon nanotubes (CNTs) exhibit high electrical and thermal conductivity and good mechanical properties, making them suitable fillers for composites. Their effectiveness as a filler is affected by their state of aggregation. Novel ordered helical wrapping of poly (methyl methacrylate) (PMMA) has been achieved on single wall carbon nanotubes (SWNTs). This carbon nanotube composite not only thwarts CNT aggregation, but also may be successfully leveraged for applications such as electrical energy storage and mechanical reinforcement.

摘要： In a method of making a high surface area carbon material, a precursor organic material is prepared. The precursor organic material is subjected to a first elevated temperature while applying a gaseous purge thereto for a first predetermined time. The precursor organic material is subjected to a second elevated temperature while not applying the gaseous purge thereto for a second predetermined time after the first predetermined time. A high surface area carbon material includes carbon and has a surface area in a range between 3029 m2/g to 3565 m2/g and a pore volume in a range between 1.66 cm3/g and 1.90 cm3/g. The high surface area carbon material may be employed in an electrode for a supercapacitor.
