SEM results indicated that both microsphere and porous materials were fabricated using emulsion stabilized by unmodified HAp nanoparticles, implying that both W/O and O/W emulsion type were obtained. The interaction between HAp and PLLA played an important role to stabilize Pickering emulsions. Stable W/O and O/W emulsions were fabricated successfully using as-received HAp particles as stabilizer by adjusting the fabricating parameters. The results indicated emulsion stability increased with the increase of HAp concentration, emulsification rate and time it is very stable when pH value of aqueous phase was adjusted to 10. Effect of PLLA concentrations, pH value, HAp concentrations, oil-water ratio, emulsification rates and times were studied on emulsion stability and emulsion type, etc. Pickering emulsion was cured via in situ solvent evaporation method. Hydroxyapatite (HAp) nanoparticle stabilized Pickering emulsion was fabricated with poly(l-lactic acid) dissolved in dichloromethane (CH 2 Cl 2 ) solution as oil phase and HAp aqueous dispersion as aqueous phase.

In this review, the preparation and properties of nanocellulose- stabilized Pickering emulsions are summarized. chemical stability, biodegradability, biocompatibility, and renewability). Among various solid stabilizers, nanocellulose may open up new opportunities for future Pickering emulsions owing to its unique nanosizes, amphiphilicity, and other favorable properties (e.g. Pickering emulsion, which is an emulsion stabilized by solid particles, offers a wide range of potential applications because it generally provides a more stable system than surfactant- stabilized emulsion.
