Hybrid acrylic/CeO₂nanocomposites using hydrophilic, spherical and high aspect ratio CeO₂nanoparticles

Abstract

A dispersion of CeO 2 nanoparticles and nanorods stabilized with nitrilotriacetic acid (NTA) and a 4,4 0azobis(4-cyanovaleric acid) (V-501) initiator has been used to initiate the emulsion polymerization of acrylic monomers, yielding stable hybrid CeO 2 nanoparticle-nanorod/polyacrylate latexes for the first time. Films cast from these hybrid latexes are transparent due to the very homogenous distribution of the polymer compatibilized CeO 2 . Furthermore, it has been proven that the UV-Vis absorption capacity of the hybrid latexes is enhanced with the incorporation of the nanorods. † Electronic supplementary information (ESI) available: Data on the particle size distribution of CeO 2 nanoparticles and nanorods, 13 C-NMR and XPS data assignments, particle size distribution of the polymer particles, stability tests and DSC and TGA measurements.

Synthesis and characterization of new branched magnetic nanocomposite for loading and release of topotecan anti-cancer drug

“…The peak at 1090 cm −1 was represent in -C-O alcoholic hydroxyl stretching and at 550 cm −1 Fig. 5 Magnetization curve versus the magnetic field (a) and XPS wide scan spectrum (b) for the MD 3 nanocomposite was demonstrated the characteristic Fe-O peak for MD 3 nanocomposite (Aguirre et al 2014;Andersson et al 2007;Kaya and Mr 2012;Souaya et al 2000). TEM images were taken to get information about the morphology and dimensions of the synthesized nanoparticles and the nanocomposite.…”

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

“…Development of such applications requires the use of a convenient matrix for efficient incorporation of the nanoparticles, to enhance the performance, avoid the cluster growth and aggregation and improve the handling and recovery of the nanoparticles. Up to now, CeO 2 particles were incorporated in various polymeric templates such as poly(meth)acrylates [ 6 , 7 , 8 ] polyurethanes [ 9 , 10 ], polyimides [ 11 ], polyamides [ 12 ] or polydimethylsiloxanes [ 13 ]. Among the plethora of polymers, one of the best candidates to immobilize CeO 2 nanoparticles (NPs), which fits both environmental and economic issues is represented by cellulose [ 14 , 15 ].…”

The synthesis of monodispersed M-CeO2/SiO2nanoparticles and formation of UV absorption coatings with them

“…[15][16][17][18] Several studies have been published on the incorporation of CeO 2 nanoparticles into polymer latex to shield UV light. [19][20][21] Most of these studies achieved good dispersion of cerium oxide via physical blending or modication with ligands or hydrogen bonds, such as citric acid, polyethylene glycol and poly(acrylate acid). [22][23][24][25] For hybrid latex obtained using these methods, the interaction between ceria nanoparticles and the organic matrix are weak, making the long-term stability of the system open to question.…”
