Effect of polymer–polymer interactions on the surface tension of colloid–polymer mixtures
The density profile and surface tension for the interface of phase-separated colloid–polymer mixtures have been studied in the framework of the square gradient approximation for both ideal and interacting polymers in good solvent. The calculations show that in the presence of polymer– polymer excluded volume interactions the interfaces have lower widths and surface tensions compared to the case...

متن کاملStructure of colloid–polymer suspensions
We discuss structural correlations in mixtures of free polymer and colloidal particles on the basis of a microscopic, two-component liquid-state integral equation theory. Whereas in the case of polymers much smaller than the spherical particles the relevant polymer degree of freedom is the centre of mass, for polymers larger than the (nano-) particles, conformational rearrangements need to be c...
متن کاملZETA POTENTIAL AND COLLOID CHEMISTRY Eric
The US Food and Drug Administration often requests the measurement of zeta potential; however, there is virtually no guidance offered in any of the regulatory pharmacopoeias. Guidelines are available in other standards, and there exists a wealth of information in texts and publications. Many of these are taken from non-pharmaceutical industries where zeta potential is routinely used as part of ...
