Properties of the Pickering emulsions of four different oils stabilized by PMDA-ODA particles (0.5 wt %). The volume ratio of oil-water was 1:6.
| Oil Used | pH of Dispersion | Conductivity of Dispersion (μS cm−1) | Conductivity of Emulsion (μS cm−1) | Type of Emulsion Formed a | Emulsion Remaining for 48 h b (%) | Mean Droplet Diameter c (μm) |
|---|---|---|---|---|---|---|
| n-Hexadecane | 4.10 | 243 | 201 | Oil-in-water | ~100 | ~19 |
| Linseed oil | 4.10 | 243 | 202 | Oil-in-water | ~100 | ~30 |
| Olive oil | 4.10 | 243 | 200 | Oil-in-water | ~100 | ~41 |
| Phenyl acetate | 4.10 | 243 | 203 | Oil-in-water | ~100 | ~59 |
a Determined by emulsion conductivity measurements and drop tests. b Calculated by Equation (2). c Measured using an optical microscope from a data set of at least 1000 measurements for each sample.
