Can I dissolve water-soluble PEDOT:PSS nanoparticle solution in chloroform?
Kim It is not soluble in chloroform, because of salvation properties the polar substance which is soluble in polar solvent. Water is highly polar solvent, as you mentioned your poly composite of nano particle is also might be a polar substance which you said soluble in water. Chloroform is non polar solvent, so the solubility of the product is lesser than water. If your nano composite consist sulphonic group possible to replace by other suitable functional group may possible to choice of chloroform rather than direct dissolution in chloroform may lead lesser extent of your component. Try it for your practical experience.
PEDOT-PSS is present in water as a highly dispersed nanoparticle. you can add the pedot-pss solution dropwise to hot dmac (>100 C) and achieve a dispersion of the PEDOT-PSS in the organic solvent. The water is soluble with dmac, but boils off and leaves the still dispersed pedot-pss naoparticles behind.
correct, even in water, PEDOT-PSS is not dissolved, but dispersed; the particle size is around 30 - 80 nm; it will not be possible to dissolve PEDOT-PSS in CHCl3, you would need to follow some more special synthesis and dispersion route, please consult this publication:
