The Fiber Diameter Prediction Model of PVDF Electrospun Lithium Separators

Abstract

With the fiber diameter of electrospun PVDF membrane in lithium cells measured by FE-SEM and the test sample designed by the BBD of RSM , a Quadratic multiple regression model got .The R-Squared(0.9466) and Adeq Precision(13.095) illustrated the model fitted the sample very well , small fluctuations between predicted and actual values also said the same result . Under taking analysis of variance and significance test of the model found that acetone mixed ratio, concentration, interaction of mixing ratio and concentration of acetone, interaction of concentration and electric field strength were significant influencing factors.

Investigation of Effect of Electrospinning Parameters on the Morphology of Polyacrylonitrile/Polymethylmethacrylate Nanofibers: A Box–Behnken-Based Study

“…[1,3,[18][19][20][21] The morphological structure and dimensions of electrospun fibers are influenced by three types of parameters: material, processing and ambient ones. Polymer type and its molecular weight, polymer concentration, solvent and polymer solution properties (viscosity, conductivity and surface tension) are some of the important material properties.…”

A review of evolution of electrospun tissue engineering scaffold: From two dimensions to three dimensions

“…The parameters involved in the development of TE scaffolds using electrospinning process can be divided into two main categories: materials aspect and machine parameters. In terms of materials, many researchers have studied solution parameters such as concentration of solution, 41–61 concentration of fillers or additives, 41,46,48,55,62 solvent ratio, 43,48,52,57,63 conductivity, 42,53 and volatility of solution. 42 The second category, process parameters, was also analyzed by many researchers in terms of applied voltage, 42–44,46,47,49–60,62,64 needle diameter, 43,46,62 flow rate, 43,44,46,47,50,51,53,…”
