Automatic Assembly and Morphological Characteristics of a Poly (Vinylidene Fluoride) and N, N-Dimethylformamide Compound “Root-Like” Fiber Structure

Gerardo Gonzalez, Paola Vazquez

Abstract


A study to describe the process to induce an automatic assembly and morphological characteristics of a Poly (Vinylidene Fluoride) and N, N-Dimethylformamide compound “root-like” fiber structure was developed.  PVDF, poly (vynylidine fluoride) is a widely investigated polymer due to its excellent mechanical properties, chemical stability and ferroelectricity. The electrospining variation with two electrodes was used to collect PVDF & DMF compound “root-like” fiber structure and these were morphologically analysed using Scanning Electron Microscopy (SEM).  The compound fiber structure presents porous round structures from which fibers extends and/ or aggregate to create a hollow cylinder that has a diameter of micrometers.  The conditions for the automatic assembly of the PVDF &DMF compound “root-like” fiber structure appear to be a unique property of the PVDF & DMF.  For the automatic assembly to occur, the distance between electrodes must be around 14.5cm, a voltage in the range of 15Kv to 30Kv and a concentration of 18%wt/wt
