Special Issue Information

Dear Colleagues,

Nanomaterials are materials with at least one dimension less than 100 nanometers that exhibit unique physical, chemical, and biological properties. With the rapid development of nanotechnology, novel functional nanomaterials have been developed, endowed with various functions such as optical, electrical, magnetic, and catalytic properties. Thus, novel functional nanomaterials are defined as materials that are designed at the nanoscale to serve a specific function in a wide range of applications.

These novel functional nanomaterials have significant potential for addressing challenges in various fields, including biomedical engineering, energy, environmental protection, and information technology. Therefore, further exploration and application of novel functional nanomaterials will undoubtedly bring more innovative ideas and solutions to solving critical societal problems.

This Special Issue focuses on the synthesis, characterization, and applications of novel functional nanomaterials. The research papers in this Special Issue will cover recent advances in the fabrication and characterization of novel materials with unique optical, electrical, magnetic, or mechanical properties at the nanoscale. The aim of this Special Issue is to present cutting-edge research in the field of nanoscience and nanotechnology and to highlight potential applications of these novel materials.

In order to separate the colloidal in high-turbidity water, a kind of magnetic composite (Fe3O4/HBPN) was prepared via the functional assembly of Fe3O4 and an amino-terminal hyperbranched polymer (HBPN). The physical and chemical characteristics of Fe3O4@HBPN were investigated by different means. The Fourier Transform infrared spectroscopy (FTIR) spectra showed that the characteristic absorption peaks positioned at 1110 cm−1, 1468 cm−1, 1570 cm−1 and 1641 cm−1 were ascribed to C–N, H–N–C, N–H and C=O bonds, respectively. The shape and size of Fe3O4/HBPN showed a different and uneven distribution; the particles clumped together and were coated with an oil-like film. Energy-dispersive spectroscopy (EDS) displayed that the main elements of Fe3O4/HBPN were C, N, O, and Fe. The superparamagnetic properties and good magnetic response were revealed by vibrating sample magnetometer (VSM) analysis. The characteristic diffraction peaks of Fe3O4/HBPN were observed at 2θ = 30.01 (220), 35.70 (311), 43.01 (400), 56.82 (511), and 62.32 (440), which indicated that the intrinsic phase of magnetite remained. The zeta potential measurement indicated that the surface charge of Fe3O4/HBPN was positive in the pH range 4–10. The mass loss of Fe3O4/HBPN in thermogravimetric analysis (TGA) proved thermal decomposition. The –C–NH2 or –C–NH perssad of HBPN were linked and loaded with Fe3O4 particles by the N–O bonds. When the Fe3O4/HBPN dosage was 2.5 mg/L, pH = 4–5, the kaolin concentration of 1.0 g/L and the magnetic field of 3800 G were the preferred reaction conditions. In addition, a removal efficiency of at least 86% was reached for the actual water treatment. Fe3O4/HBPN was recycled after the first application and reused five times. The recycling efficiency and removal efficiency both showed no significant difference five times (p > 0.05), and the values were between 84.8% and 86.9%. Full article
