Carbon nanotubes (CNTs) are regarded as ideal fi ller materials for polymeric fi ber reinforcement due to their exceptional mechanical properties and 1D cylindrical geometry (nanometer-size diameter and very high aspect ratio). The reported processing conditions and property improvements of CNT reinforced polymeric fi ber are summarized in this review. Because of CNT polymer interaction, polymer chains in CNTs ’ vicinity (interphase) have been observed to have more compact packing, higher orientation, and better mechanical properties than bulk polymer. Evidences of the existence of interphase polymers in composite fi bers, characterizations of their structures, and fi ber properties are summarized and discussed. Implications of interphase phenomena on a broader fi eld of fi ber and polymer processing to make much stronger materials are now in the early stages of exploration. Beside improvements in tensile properties, the presence of CNTs in polymeric fi bers strongly a ff ects other properties, such as thermal stability, thermal transition temperature, fi ber thermal shrinkage, chemical resistance, electrical conductivity, and thermal conductivity. This paper will be helpful to better understand the current status of polymer/CNT fi bers, especially high-performance fi bers, and to fi nd the most suitable processing techniques and conditions.請小伙伴們下載后給個好評! |
