Study of polypyrrole functionalization parameters
The polypyrrole was functionalized by reaction with glutardialdehyde in order to insert further binding sites on the polymer surface for covalent immobilization of enzymes. Five parameters of functionalization reaction were studied: the catalyst (sulphuric acid) concentration, glutardialdehyde/water ratio, polypyrrole/functionalization solution ratio, temperature and time. The effect of each parameter was determined by keeping the other four constant.
