What is Spray Dried Hydroxyapatite-based Supraparticles with Uniform and Controllable Size and Morphology about?
This work aims to prepare uniform spray dried hydroxyapatite-based (SD HAP-based) supraparticles with controllable morphology via micro-fluidic spray drying. Sodium polyacrylate (PAAS) and sodium chloride (NaCl) were used to prepare the precursor suspensions by regulating the inter-particle repulsive forces and electrostatic shielding effect, respectively. The particle size (D50) and zeta potential of the suspension were highly associated with the mass ratio of HAP to PAAS (m H /m P ) and the NaCl concentration (C NaCl ), which further had significant effect on the permeability (k) of the droplet shell formed during spray drying and ultimately the supraparticle morphology. D50 ˂ 2 μm and absolute zeta potential ˃ 20 mV, obtained when m H /m P ˂ 100 under low C NaCl , rendered ultralow k and consequently deformed supraparticles; Whereas D50 ˃ 2 μm and absolute zeta potential ˂ 20 mV, achieved by decreasing PAAS amount, i.e. m H /m P ≥ 100 or improving C NaCl to efficiently screen surface net charge of HAP, high k and spherical supraparticles were thus preferentially formed.
