Synthesis and functionalization of zinc phosphate@polyglycidyl methacrylate composites for antimicrobial drug immobilization and controlled release: an in vitro study

Abstract

Nowadays, development of functional polymer-coated inorganic composite particles is one of the important topics of investigation for biomedical applications. Although, several studies have tried to design hybrid nanocomposites, this study...

Capturing Acidic CO2 Using Surface-Active Difunctional Core–Shell Composite Polymer Particles via an Aqueous Medium

“…This increment in sizes is because of the hydration layers of polar groups via hydrogen bonding with water, while the SEM analyses were performed in the dried state of solid particles, where was not any possibility of swelling of the particles. , To evaluate elemental compositions of the surface of both reference PS/P­(MMA-AAm-EGDMA) and aminated PS/P­(MMA-AAm-EGDMA) composite particles, SEM-EDX elemental mapping measurements were conducted, and the obtained data are shown in Figures S4and d–g, respectively. EDX elemental combined mapping revealed the presence of C, N, and O as their elements in both the reference and aminated composites . The individual atom distributions for C, N, and O were revealed from the surface of particles (Figure e–g).…”

“…The PS seed particles are spherical shaped with a smooth and hard surface, which is clearly visible in the SEM image. After seeded copolymerization of PS seed particles, the size increased and the surface morphology was also slightly improved. , However, successive amine functionalization of PS/P­(MMA-AAm-EGDMA) particles fairly altered the surface topology, while the shape of the aminated composite particles was unchanged . The average diameters of the PS seed (Figure a), reference composite (Figure b), and aminated composite polymer particles (Figure c) were 1706.61, 1976.56, and 1968.94 nm, respectively.…”
