Preparation of porous polycaprolactone tubular matrix by salt leaching process
Salt leaching technique has been employed to produce polycaprolactone (PCL) based porous tubular matrix. Salt was dispersed into PCL solution in chloroform and the subsequent leaching of salt was accomplished in water. The effect of salt and polymer concentration on the mechanical properties, porosity and surface characteristics was studied. It was observed that salt concentration has significant influence over crystalline nature of the scaffold. The porous structures became more interconnected as the salt concentration increased. This process yields a tubular porous matrix with maximum porosity of 61%, strength of 1.84 (+/- 0.04) MPa and tensile strain of 120 (+/- 7.94). (c) 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
