“…The peak at 44.788 of PANI/nZVI was weaker and broader compared with that of nZVI, indicating that the particle size of iron nanoparticles supported on PANI was much smaller than that of nZVI. The broad band centered at 2u 5 20.348 confirms the amorphous feature of PANI [30].…”

In this study, the PANI‐supported nanoscale zero‐valent iron (PANI/nZVI) composites have been successfully synthesized to remove Rhodamine B (RhB) from aqueous solutions using a heterogeneous Fenton‐like system. The synthetic PANI/nZVI composites were characterized using X‐ray diffraction (XRD), Transmission electron microscope (TEM) and Fourier transform infrared (FTIR). The results showed that they were lamellar structures and nZVI nanoparticles were introduced into their structures. The performances of PANI/nZVI composites on the activation of molecular oxygen for removal of RhB were investigated and the effects of operating parameters, such as PANI/nZVI dosage, PANI and nZVI mass ratio, RhB initial concentration, and pH value on RhB removal were also discussed. The results indicate that PANI/nZVI was proved to be the most efficient in that more than 83.31% of RhB was removed, whereas only 11.15% when using nZVI after reacting for 120 min with an initial RhB concentration of 0.02 mmol L−1 (pH = 6.50). Furthermore, the reaction mechanism was discussed by measuring the concentrations of Fe(II), total Fe and H2O2 formed in the system and examining scavenging effects using copper chloride and methanol. Finally, the stability of PANI/nZVI nanocatalyst was studied. © 2015 American Institute of Chemical Engineers Environ Prog, 35: 48–55, 2016

“…Preparation of DPSP DR 28 is an azo and anionic dye ( Figure 1), and is widely used in the dyeing processes for textiles, paper, plastic, rubber and processed food [34]. The dye is water-soluble because of the ions (SO 3 − ) on its naphthalene nuclei, making the dyeing process simple.…”

Filling and colorating are two important procedures in the polymer production. In this work, a bio-filler dye-loaded shell powder (DPSP) was prepared at first and then its filling and colorating effects on low density polyethylene (LDPE) polymer were investigated. SEM analysis showed the good dispersion of DPSP and strong interfacial adhesion. Mechanical property studies indicated that the incorporation of DPSP had an excellent filling effect at lower loading rate. Uniform color distribution in the specimens was also obtained at the premise of improving the mechanical performance of LDPE polymer. Vicat softening temperature tests indicated that the incorporation of DPSP could enhance the heat resistance of the composites. The optimal additive amount of DPSP was determined as 10 wt.% with a good balance between toughness and stiffness of LDPE composites.

Magnetic nanofibers (MNFs) are integrated with a variety of properties, such as large surface area, high porosity, small size effect and apparent magnetism. This enables MNFs to possess excellent properties of both nanofibers (NFs) and magnetic materials, which greatly widens the application of the original magnetic materials. A brief review of the properties of MNFs, fabrication techniques, and their emerging applications which include biomedical application, sensing and electronic devices, wastewater treatment and microwave absorption is presented. Finally, the development trend and prospect of MNFs in future are summarized and discussed.
