摘要

目前，静电纺丝纤维直径的预测数学模型有Fridrikh模型、Spivak模型和Stepanyan模型。前两种模型的两个主要参数是纺丝液的表面张力和射流的体积电荷密度，Stepanyan模型的两个主要参数是纺丝液的零剪切粘度和射流的体积电荷密度。从已报道的实验研究来看，纤维直径与纺丝液的这三个重要参数之间的幂指数与数学模型中的理论幂指数基本上不一致。导致这个结果的主要原因有：(1)非Newtonian流体已是主要的电纺丝对象，这三个数学模型都是以Newtonian流体而建立的；(2)这三个参数都不是独立变量等，并提出了静电纺丝在这方面的研究方向。

Abstract

Three mathematical models for predicting the diameter of electrospun fibers were established respectively by Fridrikh

Spivak

Stepanyan from the electrospinning mechanism so far. The two main parameters of the ahead two models are the surface tension of solution and volume charge density of jet. The two main parameters of the Stepanyan model are zero shear viscosity of electrospun solution and volume charge density of jet. On the basis of the experimental reports of power exponents between the electrospun fiber diameter and the three parameters at present

The experimental results generally are not consistent with the model predictions. The main reasons of resulting in the disagreements are: (1) The mathematical models are based on Newtonian fluid

but non-newtonian fluids have already been the main electrospun objects; (2) Neither of the three parameters is not independent variables

etc. The respect research directions of electrospinning were put forward.
