| Fig. 10. Influence of PER addition on the microscopic morphology of biodiesel-based emulsion. (a) The emulsion droplets are uniformly dispersed without adding PER; (b) Some emulsion droplets gather together when adding 0.1% PER; (c) The emulsion droplets gather and connect with each other when adding 0.5% PER; (d) Many emulsion droplets gather and connect to a gel network when adding 1.0% PER; (e) Many emulsion droplets gather and form a denser gel network when adding 2.0% PER. |
