Preparation and structural characterization of sodium polyphosphate coacervate as a precursor for optical materials
(2016-09-01)
This paper describes the preparation of Sodium Polyphosphates Coacervates (NaPC) through the direct addition of different methanol molar fractions to a sodium polyphosphate solution. The presence of methanol reduces the ...
The impact of P/Ca molar ratio on physicochemical and release properties of calcium polyphosphate coacervates
(2021-05-01)
This paper reports on the synthesis and characterization of gel-like calcium polyphosphate coacervates (Ca–PPCs) with three different [P]:[Ca] ratios as new matrixes for drug release. Caffeine and chlorhexidine were used ...
