Doped functional polymers, such as magnetic self‐healing polymers based on magnetic inorganic nanoparticles, have raised great attention and been applied in many fields recently due to their superior properties. However, the deficiency of interface compatibility between the inorganic nanoparticles and organic polymers, and the sedimentation and non‐uniform dispersion of the inorganic nanoparticles led to difficulties in the fabrication and development of doped functional polymer materials. In this work, we took magnetic doped self‐healing polymers as an example and proposed an accessible method to solve the problem. We prepared organic‐polymer‐coated Fe3O4 nanoparticles with high interface compatibility and then applied them to successfully synthesize magnetic self‐healing polymers. The average size of the resulting coated Fe3O4 nanoparticles was 8.82±1.09 nm, the practical saturation magnetization of the nanoparticles and the magnetic self‐healing polymers was 83.35, 24.29 emu/g, respectively. In addition, the self‐healing efficiency of the magnetic self‐healing polymers could reach 74.3% when healing for 1 hour and 78.4% when adding a magnetic field compared with 75.8% for the pure self‐healing polymers and 34.5% of magnetic polymers based on pure Fe3O4 nanoparticles. This work may offer a reference in fabricating doped functional polymers based on inorganic nanoparticles with high interface compatibility.

“…The temperature range of 30–150°C is characteristic for a loss of residual water and other contaminations, as well as for physically adsorbed molecules. In the temperature range of 150–600°C, carboxyl, hydroxyl, carbonyl, and nitrogen groups of chemically adsorbed molecules undergo decomposition (Lesiak et al, 2009; Stobinski et al, 2010, 2012; Linh et al, 2018), contributing to this weight loss, whereas higher temperatures are more characteristic for phase transformations. The weight loss for all the investigated samples in the first range varies from 2.3 to 5.4% and is larger for oxalic (5.4%) and citric (4.6%) acids indicating either higher surface hydrophilicity and/or physical adsorption.…”

“…The cytotoxicity of Fe 3 O 4 MNPs coated with a wide variety of biocompatible admolecules has been recently extensively studied (Gupta and Gupta, 2005; Kim et al, 2009, 2010; Tomitaka et al, 2012; Mahdavi et al, 2013; Sahu et al, 2015; Taghavi et al, 2016; Hu et al, 2017; Linh et al, 2018). These several studies showed that cytotoxicity depends on the type of the investigated cells, type of biocompatible adlayer on MNPs, MNP size, concentration of MNPs, pH of solution, and time of incubation.…”

“…For the concentration range of 0.012–0.1 mg mL −1 , the generation of ROS by Fe 3 O 4 nanoparticles was found to be smaller in comparison to Pt and PEGylated mesoporous iron–platinum–iron(II, III) (FePt-Fe 3 O 4 ) nanoparticles (Sahu et al, 2015). Recently, it has been reported that Fe 3 O 4 MNPs exhibited no cytotoxicity for HeLa cells during incubation time from 24 to 72 h, whereas coated MNPs showed the cytotoxicity after 72 h (Linh et al, 2018). No effect of Fe 3 O 4 MNPs on cytotoxicity for HeLa cells was observed for incubation time of 24 h elsewhere (Gupta and Gupta, 2005; Kim et al, 2009, 2010; Tomitaka et al, 2012).…”

Surface Study of Fe3O4 Nanoparticles Functionalized With Biocompatible Adsorbed Molecules

Surfaces of iron oxide of ferrimagnetic magnetite (Fe3O4) nanoparticles (MNPs) prepared by Massart's method and their functionalized form (f-MNPs) with succinic acid, L-arginine, oxalic acid, citric acid, and glutamic acid were studied by dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR-S), UV-vis, thermogravimetric analysis (TGA)/differential scanning calorimetry (DSC), X-ray photoelectron spectroscopy (XPS), and reflection electron energy loss spectroscopy (REELS). The XPS analysis of elements and their chemical states at the surface of MNPs and f-MNPs revealed differences in chemical bonding of atoms, content of carbon–oxygen groups, iron oxide forms, iron oxide magnetic properties, adsorbed molecules, surface coverage, and overlayer thickness, whereas the Auger parameters (derived from XPS and Auger spectra) and elastic and inelastic scattering probabilities of electrons on atoms and valence band electrons (derived from REELS spectra) indicated modification of surface charge redistribution, electronic, and optical properties. These modified properties of f-MNPs influenced their biological properties. The surfaces biocompatible for L929 cells showed various cytotoxicity for HeLa cells (10.8–5.3% of cell death), the highest for MNPs functionalized with oxalic acid. The samples exhibiting the largest efficiency possessed smaller surface coverage and thickness of adsorbed molecules layers, the highest content of oxygen and carbon–oxygen functionalizing groups, the highest ratio of lattice O2− and OH− to C sp2 hybridizations on MNP surface, the highest ratio of adsorbed O− and OH− to C sp2 hybridizations on adsorbed molecule layers, the closest electronic and optical properties to Fe3O4, and the lowest degree of admolecule polymerization. This high cytotoxicity was attributed to interaction of cells with a surface, where increased content of oxygen groups, adsorbed O−, and OH− may play the role of additional adsorption and catalytic sites and a large content of adsorbed molecule layers of carboxylic groups facilitating Fenton reaction kinetics leading to cell damage.

“…Magnetic nanoparticles can be used individually or assembled into larger structures to perform a function more efficiently than a bulk material, whether that function is to do move, bend, absorb energy, or some other process. This has led to applications in fields as widely varied areas as electronic components [4], biomedical applications [5,6], and magnetically recoverable catalysts [7].…”
