Hsu J.-P.Kuo Y.-C.2019-05-202019-05-20199500219606https://scholars.lib.ntu.edu.tw/handle/123456789/409431The electrostatic interactions between spherical particles suspended in an electrolyte solution is analyzed. The surfaces of these particles are coated with an ion-penetrable membrane, which bears nonuniformly distributed fixed charges. We consider two classes of fixed charge distributions; these distributions all yield the same amount of total fixed charges in the membrane phase. The exact solution to the governing Poisson-Boltzmann equation is derived for the case the potential of the system under consideration is low. Based on this solution, the stability ratio and the critical coagulation concentration of a dispersed system are estimated. ? 1995 American Institute of Physics.journal article10.1063/1.4696122-s2.0-0001720286https://www.scopus.com/inward/record.uri?eid=2-s2.0-0001720286&doi=10.1063%2f1.469612&partnerID=40&md5=a6eef32fbb312102b3757d0ebe1eea0c
