Influence of chemical structure of bile acid dispersants on electrophoretic deposition of poly(vinylidene fluoride) and composites

A biomimetic strategy has been developed for the dispersion of poly(vinylidene fluoride) (PVDF) particles using commercial analogs of bile acids (BAs), such as lithocholic acid (LCA), chenodeoxycholic acid (CDCA), deoxycholic acid (DCA), ursodeoxycholic acid (UDCA), and cholic acid (CA). BAs were used as anionic surfactants for electrophoretic deposition of PVDF films. The EPD method allowed controlled deposition of PVDF films at high deposition rates. The PVDF deposition yield, obtained using different BAs, increased in the order LCA
