Fibrous Scaffold Produced By Rotary Jet Spinning Technique

摘要

Poly(L-lactic acid) (PLLA)/ poly(?-caprolactone) (PCL) mesh was produced by Rotary Jet Spinning (RJS) process. RJS is a simple method which fabricates three-dimensional fibers by exploiting a high-speed rotating nozzle o form a polymer jet which undergoes stretching before solidification without the need of high voltage. Blend meshes were characterized by scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), differential scanning calorimeter (DSC) and infrared spectroscopy Fourier transform (FTIR). SEM imagens provides information about the morphological structure, which confirmed the production of fibers using RJS. Data obtained by thermal analyzes indicated the immiscible property of PLLA/PCL blend and also the total solvent evaporation
