Mathematical Model Equation Development for Optimization of PVDF Membrane Surface Properties

Abstract

This paper aims to develop mathematical models to optimize the surface properties of PVDF membrane modified by superhydrophobic macromolecules. The mainapplication of these surface engineered membranes is in membrane distillation for treatment of water and desalination purposes. Response surface methodology (RSM) was applied in the variables and their independent and concert responses on the surface features. To achieve this goal, the three-level three-factorial Box– Behnken experimental design was chosen for finding out the relationship between the response functions (contact angle, pore size and overall porosity) and variables (PVDF concentration, SMM concentration and solvent evaporation time).
