Preliminary Fabrication of Polymer Membranes from Renewable Resources

Abstract:

Polymer membranes from renewable material with controlled pore size and structure were produce using phase inversion technique. The optimal conditions for the preparation of polymer membranes was polymer concentrations in N,N-dimethylformamide (DMF) solution 12 % (w/v), 15 % (w/v), 18 % (w/v) and 21 % (w/v). This is due to the types of structure; pinhole-like structure and interconnected network structure. The structure of the membranes consisted of thick fibrill elements. The polymer membrane cross-section is composed of stacks of separate layers. Permeability of the polymer membranes obtained at lower concentrations, gives highest value of 0.161, 0.015, 0.001 and 0.00051 L/s.m³ for 12 %, 15 %, 18 % and 21 % (w/v) respectively. Evidently, as the concentration of the polymer in DMF increases, the tear strength decreases. Meanwhile, for lower concentration in N,N-dimethylformamide (DMF), gave highest strength due to low membranes wall thicker. Thus, the membranes are easily break compared to the membranes that have high porosity as shown by tear test of 12 % with 21.8495 N/mm tear strength.
