Preparation and Characterization of ABS/PVC Blend Membrane

Study of preparation and characterization of polymer membrane is important with the
intention to find the membrane process that are economically feasible and also can obtain
highly permeable and selective membranes which are good in mechanical aspect and
achieved thermal stability. This report contained the preparation and characterization of
Poly Vinyl Chloride/ Acrylonitrile Butadiene Styrene polymer blend or also known as
PVC/ABS blends.
Objectives and scope of the project includes the study of method and preparation
process of membranes and characterization of the prepared membrane. In preparation
process, solubility of polymer in solvent, effect of polymer concentration and rate of
evaporation is observed and analyzed. While for characterization of membrane, only
surface charges ofthe polymer membrane is tested. Further characterization experimental
can not be carrying out due to time constraint and unavailable equipments. Methodology
and procedure of all the experiments is explained in detail in Chapter 3:
In solubility experiment, the result showed that both polymers are most and
fastest dissolved in Tetra Hydro Furan (THF). More over, the perfect condition and fast
rate of evaporation is inside the fume hood and let it open to surrounding air. The
membranes that were produced are at the best condition for the characterization purpose
later on. The membranes that were produce are different in concentrations which are
7%wt, 10%wt, 12%wt and 15%wt. Characterization measurement of the membranes
shown that the polymer membranes which contain high weight percent of ABS is posses
more negative charge compare to the polymer which contain high weight percent ofPVC
All the results are further discussed in chapter4: Result and Discussion.
