Karbon nanotüplerin artan popülaritesi, nanoyapılı malzemelerdeki termal iletim özelliklerinin daha fazla bilimsel olarak anlaşılması için bir talep oluşturdu. Buna karşın, karbon nanotüp filmlerin ve fiberlerin termal iletkenliği üzerine kirliliklerin, yanlış hizalamaların ve yapı faktörlerinin etkileri tam olarak hala anlaşılamamıştır. Karbon nanotüp filmleri ve fiberleri üretildi ve termal iletkenliğini belirlemek için paralel termal iletkenlik tekniği çalışıldı. Nano yapılı malzemede termal iletim özelliklerini anlamak için karbon nanotüp yapısının, saflığın ve hizalamanın karbon filmlerin ve fiberlerin termal iletkenliği üzerine etkileri araştırıldı. Hacim yoğunluğunun ve kesit alanının önemi deneysel olarak belirlendi. Sonuçlar, hazırlanan karbon nanotüp filmlerinin ve fiberlerin ısı iletiminde çok verimli olduğunu göstermiştir. Karbon nanotüplerin yapısı, saflığı ve hizalaması, karbon filmlerin ve fiberlerin ısı iletim özelliklerinin belirlenmesinde esasen önemli bir rol oynar. Tek duvarlı karbon nanotüp filmleri ve fiberler genellikle yüksek termal iletkenliğe sahiptir. Karbonlu olmayan safsızlıkların varlığı, demet temasının düşük olması sebebiyle termal performansı azaltır. Termal iletkenlik, sıcaklığa bağlı olarak güç yasasını gösterebilir. Spesifik termal iletkenlik, artan hacim yoğunluğuyla azalır. Oda sıcaklığında maksimum spesifik termal iletkenlik elde edilir ancak Umklapp saçılması meydana gelir. Karbon nanotüp fiberlerin özgül termal iletkenliği, artan demet hizalama derecesinden dolayı karbon nanotüp filmlerinkinden önemli ölçüde daha yüksektir.

The increasing popularity of carbon nanotubes has created a demand for greater scientific understanding of the characteristics of thermal transport in nanostructured materials. However, the effects of impurities, misalignments, and structure factors on the thermal conductivity of carbon nanotube films and fibers are still poorly understood. Carbon nanotube films and fibers were produced, and the parallel thermal conductance technique was employed to determine the thermal conductivity. The effects of carbon nanotube structure, purity, and alignment on the thermal conductivity of carbon films and fibers were investigated to understand the characteristics of thermal transport in the nanostructured material. The importance of bulk density and cross-sectional area was determined experimentally. The results indicated that the prepared carbon nanotube films and fibers are very efficient at conducting heat. The structure, purity, and alignment of carbon nanotubes play a fundamentally important role in determining the heat conduction properties of carbon films and fibers. Single-walled carbon nanotube films and fibers generally have high thermal conductivity. The presence of non-carbonaceous impurities degrades the thermal performance due to the low degree of bundle contact. The thermal conductivity may present power law dependence with temperature. The specific thermal conductivity decreases with increasing bulk density. At room temperature, a maximum specific thermal conductivity is obtained but Umklapp scattering occurs. The specific thermal conductivity of carbon nanotube fibers is significantly higher than that of carbon nanotube films due to the increased degree of bundle alignment.
