Published: Feb. 20, 2025

This study introduces an eco-friendly approach to fabricating superstrong, core-shell, composite microcapsules, offering a sustainable alternative traditional insoluble microplastic-based materials like melamine-formaldehyde. These microcapsules were engineered with thick CaCO3 shell formed via crystal ripening in the presence of water-soluble poly(acrylic acid), encasing hexylsalicylate oil core armored by hydrophilic SiO2 nanoparticles. An additional polydopamine layer was deposited oxidative autopolymerization at pH 8.5 for improved structural and surface properties resulting microcapsules. (D 3,2 = 8.8 ± 0.3 μm) spherical, relatively smooth surface, exhibited unique mechanical properties, which are essential broaden their applications industry. Remarkably, compression tests showed mean rupture stress 73.5 5.0 MPa, dramatically surpasses any other inorganic/synthetic microcarrier reported literature. In addition, only 10-20% active released within 2 h into mixed water-propanol medium used as accelerated release test, where solubility is high, full over 3 days. Herein, we also propose novel pathway-specific binding constant (PSBC) that describes strong interaction between Ca2+ ions connection stoichiometric ratio. Overall, these hold promise multiple fast-moving consumer goods, maximizing strength encapsulation valuable functional actives paramount; this includes but not limited energy storage, household, agrochemical, personal care, healthcare applications.
