摘要

Pan-based carbon fiber has enormous commercial applications due to its high modulus and high strength. But in recent decades there has no great progress in tensile strength and modulus of pan-based carbon fiber [1]. The primary reason is the heterogeneity of internal defects such as fiber surface groove, wire surface defects, and crystallinities [2,3]. In order to obtain good performance of carbon fiber, the fine denier, high purification, micro crystallization and homogenizing polyacrylonitrile base of the original silk is the primary premise. Electrostatic spinning broke limitations of the conventional dry spinning as well as the dry-jet wet-spinning, which can be used to prepare the nanometer level precursor, thus make the pan-based carbon fiber huge properties of ascension may provide the witnessed [4,5]. However, in electrostatic spinning, how to pure research diameter of fiber for fiber morphology and the influence of the structure and the other factors into has been bothering you. In this paper, to solve the stability of continuous flow water bath collection system, and on the basis of electrostatic spinning process through simple changes in the flow velocity of the spinning solution, get the different diameter of electrostatic spinning polyacrylonitrile fiber the nano [6]. The diameter changes of electrostatic spinning polyacrylonitrile fiber and morphology of the nano gathered state the influence of the structure were also investigated.
