Point of Zero Charge - an overview | ScienceDirect Topics
P. Tengvall, in Comprehensive Biomaterials, 20114.406.2.3 Negatively/Positively Charged Surfaces Negatively charged surfaces are surfaces with a negative charge in physiological environments (pH 7). Such surfaces possess an isoelectric point (pI or point of zero charge, pzc) below pH 7. 16–18 Some oxides are strongly acidic, for example, SiO 2 (pzc ∼1.7–3.5), WO 3 (pzc ∼0.2–0.5), Ta
