In Situ Synthesis of Hybrid Inorganic–Polymer Nanocomposites

Abstract

Hybrid inorganic–polymer nanocomposites can be employed in diverse applications due to the potential combination of desired properties from both the organic and inorganic components. The use of novel bottom–up in situ synthesis methods for the fabrication of these nanocomposites is advantageous compared to top–down ex situ mixing methods, as it offers increased control over the structure and properties of the material. In this review, the focus will be on the application of the sol–gel process for the synthesis of inorganic oxide nanoparticles in epoxy and polysiloxane matrices. The effect of the synthesis conditions and the reactants used on the inorganic structures formed, the interactions between the polymer chains and the inorganic nanoparticles, and the resulting properties of the nanocomposites are appraised from several studies over the last two decades. Lastly, alternative in situ techniques and the applications of various polymer–inorganic oxide nanocomposites are briefly discussed.

Cellulose Acetate Incorporating Organically Functionalized CeO2 NPs: Efficient Materials for UV Filtering Applications

“…The homogeneous and complete distribution of the inorganic phase in the organic matrix in the case of hybrid composites favors the enhancement of the interfacial surface area, thus optimizing the organic–inorganic interactions responsible for the improvement of the final properties of the materials. However, this target is difficult to attain, especially due the inherent immiscibility between inorganic and organic phases, reason for that extensive research has been devoted to the chemical modification of inorganic nanoparticles [ 28 ]. The functionalization of CeO 2 nanoparticles with silane sequences aimed to improve the compatibility between the inorganic units and the cellulose matrix with a direct effect on their better dispersion, reduced aggregation and stabilization in the organic material.…”

Long‐range dipole–dipole energy transfer enhancement via addition of SiO2/TiO2 nanocomposite in PFO/MEH‐PPV hybrid thin films

“…Several strategies have been developed to prepare well‐defined inorganic/organic hybrid NCs. The most common of these strategies are via starlike polymer as nanoreactors, sol–gel, in situ polymerization, and solution blending method . In this study, poly (9,9 ′ ‐di‐n‐octylfluorenyl‐2.7‐diyl) (PFO) as a donor and poly [2‐methoxy‐5‐(2‐ethyl‐hexyloxy)‐1,4‐phenylenevinylene] (MEH‐PPV) as an acceptor were blended at various ratios with and without a SiO 2 /TiO 2 NC by the solution blending method.…”

“…96-101-1108, a = b = c = 3.911 Å), 3 This FCC structure can be indexed to its crystalline data (JCPDS card no. 96-901-1613, a = b = c = 4.065 Å), 4 This FCC structure can be indexed to its crystalline data (JCPDS card no. 96-101-1608, a = b = c = 4.079 Å).…”

“…Over the past years, polymers and their related metallic compounds have been considered as promising and suitable materials to modify the enhancement energy and resolve the environmental crisis for many applications such as water treatment, air-batteries, and opto-electronics, due to uniform structures and their surface properties [1][2][3][4]. Several reports have shown that polymers act as stabilizers and hosts for metallic nanoparticles because the functional groups of the polymer chain contain electron-donor functional groups (hydroxyl, amine, etc.)…”
