“…An alternative approach to composite CNC–polymer materials relies on the use of CNCs and latex nanoparticles (NPs). Latex NPs can be synthesized with a broad range of compositions, dimensions, morphologies, and surface chemistries, − which would broaden the range of applications of CNC–polymer composite materials. Importantly, both hydrophilic and hydrophobic latex NPs can be introduced in aqueous CNC suspensions.…”

Cellulose nanocrystals (CNCs) form cholesteric films that exhibit birefringence, iridescence, and circular dichroism; however, these films are brittle and prone to cracking. Here we report composite cholesteric films formed from CNCs and soft reactive latex nanoparticles (NPs) (the latter underwent in situ cross-linking during film formation). Composite films exhibited a self-stratified morphology, with lateral cholesteric CNC-rich layers and isotropic latex NP-rich layers. The films retained their photonic properties and exhibited significantly enhanced mechanical properties. In comparison with latex-free CNC films, composite films had an ∼60% higher toughness but did not compromise their tensile strength. The combination of photonic performance and improved mechanical properties of the composite nanocellulose films expands the range of applications of these materials for the fabrication of optical devices.

“…Fan et al [65] found that the electrostatic attraction brought by MTC was of vital importance for the adsorption of SiO 2 and the formation of raspberry-like morphology, and the amount of AIBA had little effect on the SiO 2 content as well as the core-shell morphology. Zhang's team [66][67][68] synthesized polymer@SiO 2 core-shell composite particles under different systems (such as emulsion polymerization, microemulsion polymerization, and dispersion polymerization) by employing MTC as the auxiliary comonomer. Hwang et al [69] coated a layer of SiO 2 on P(MMA-MTC) surface by the Stöber method, and further synthesized the superhydrophobic particles by coupling P(MMA-MTC)@SiO 2 particles with fluoroalkyl silane.…”

Polymer@SiO2 Core–Shell Composite Particles: Preparation and Application

et al. 2023

In recent years, core–shell composite particles with organic polymer as the core and inorganic SiO2 as the shell have attracted widespread attention and prompted robust scientific endeavors. The encapsulation of SiO2 can endow the polymer core with a variety of important properties, and is of great significance for the synthesis of multi–functional materials, having favorable application prospects in coating, polishing, medical, optical, magnetic, lubrication and other fields. In this paper, the recent advances in the preparation of core–shell polymer@SiO2 composite particles are reviewed. From the perspective of interface bonding mechanisms between the core and the shell, this paper mainly focused on the following five aspects: Pickering stabilization, acid–base interaction, charge interaction, bridging of coupling agent, hydrogen bonding, and other actions. Additionally, applications of core–shell polymer@SiO2 particles are also discussed. It is expected that this article can provide scientific guidance for the preparation of polymer@SiO2 core–shell particles, further enriching their species and broadening their applications.
