A thermo-electric heating assembly for forced air, residential and commercial heating, ventilation and air conditioning (HVAC) systems includes a housing, a controller and a plurality of carbon nanotube (CNT) heating elements, arranged in the housing. The controller is adapted to respond to a signal received by the controller indicating a need for heat by powering the carbon nanotube (CNT) heating elements at a controlled electrical power level for a controlled period, commensurate with the indicated need for heat. The CNT heating elements include upper and lower metallic radiator, at least two composite containment vessel and at least two 3D CNT graphene films. The CNT heating elements preferably include a third composite containment vessel and a layer of MgSO.sub.4 or MgO.

A system for inductive heating of an aircraft surface includes a conductive outer layer configured to be located on an outer portion of the aircraft surface. The system further includes a carbon nanotube (CNT) yarn configured to receive and conduct electrical current. The system further includes an insulator located between the conductive outer layer and the CNT yarn such that the electrical current flowing through the CNT yarn generates induction heating on the conductive outer layer.

Solder-carbon nanostructure composites and methods of making and using thereof are described. Such composites can be useful for thermal application and can serve, for example, as thermal interface materials (TIMs).

Provided is a fibrous carbon nanostructure that is easy to surface modify. A symmetry factor of a peak of a first derivative curve of a thermogravimetric curve obtained through thermogravimetric analysis of the fibrous carbon nanostructure in a dry air atmosphere is 3.70 or less. The first derivative curve of the thermogravimetric curve can be a temperature derivative curve of the thermogravimetric curve or a time derivative curve of the thermogravimetric curve.

The present disclosure relates to a polymeric blend composite comprising Poly Ether Ketone/Poly-(2,5-Benzimidazole) containing pre-treated multi walled carbon nanotubes (MWCNTs) between 0.5 to 5 wt % were melt processed on a twin-screw extruder and granules so obtained were injection molded to determine heat deflection temperature (HDT) of these composites and storage modulus using DMA. It was found that HDT and storage Modulus for so produced reinforced blends were unexpectedly extremely high as compared to PEK/ABPBI blends without MWCNTs.

A polymer material molded product includes a polymer material and a porous carbon material having an X-ray diffraction spectral characteristic shown in the following (1) or (2), (1): a peak derived from a (002) plane of carbon is observed, a half width of the peak derived from the (002) plane of carbon is 5° or more, and a half width of a peak derived from a (10) plane of carbon is 3.2° or less, and (2): the peak derived from the (002) plane of carbon is not observed, and the half width of the peak derived from the (10) plane of carbon is 3.2° or less.

A method for creating a carbon nanotube heater assembly includes creating a carbon nanotube heater with varying resistances and attaching the carbon nanotube heater to both carrier and encapsulating materials. Creating the carbon nanotube heater with varying resistances is accomplished by applying a carbon nanotube mixture to a substrate, adjusting the thickness or width of the carbon nanotube mixture, and drying the nanotube mixture.
