Electrospun nylon 6 fibrous membrane coated with rice-like TiO2 nanoparticles by an ultrasonic-assistance method

Controlled assembly of superparamagnetic iron oxide nanoparticles on electrospun PU nanofibrous membrane: A novel heat-generating substrate for magnetic hyperthermia application

“…For the samples of MNF 1 and MNF 2 , a large number of individual nanoparticles Fe 3 O 4 are anchored strongly and distributed homogenously on the surface of nanofiber, unlike in previously reported cases where nanoparticles formed aggregates[22].Judging from FESEM and TEM images, it should be noted that the coverage density of Fe 3 O 4 NPs being assembled on the PU nanofibers is directly proportional to the amount of redispersed Fe 3 O 4 NPs in a polyol medium. Generally, in order to functionalize surface of electrospun nanofibers with metal or metal oxide nanoparticles, many of reports were used the immersion technique followed by post treatment in the presence of surfactant, sensitizing and stabilizing reagent[34][35][36]. However, here, our PU nanofibers have been completely covered by a sheath of densely packed Fe 3 O 4 NPs without using any additional chemicals to modify the nanofiber surfaces except of ethylene glycol dispersion medium.…”

Engineering Surface and Optical Properties of TiO2-Coated Electrospun PVDF Nanofibers Via Controllable Self-Assembly

“…It should be noted that the TiO 2 rice-like distribution was reported to be a highly efficient coating mode because it highly increased the specific surface area of the coating layer with a TiO 2 size of ~30–50 nm [ 27 ]. The increase in the infrared extinction could be as high as 195 cm −1 .…”

“…The fourth mode is the rice-like geometry of the TiO 2 nanoparticles coated on the surface of electrospun fibers. For example, Zhao et al [ 27 ] prepared nylon 6 fibers with a TiO 2 rice-like coating and investigated their extinction capacities. The results indicated a high increase of almost 200 cm −1 in the extinction coefficient after the TiO 2 rice-like coatings.…”

Silver polyhedron coated electrospun nylon 6 nano‐fibrous membrane with good infrared extinction, ultraviolet shielding and water vapor permeability

“…Fibrous materials, especially nano‐fibers, have large surface areas. Coating such materials with metal or metal oxide can impact exceptional properties, such as catalysis, radiation shielding and antimicrobial 1–4. In particular, silver is a popular coating material because of its diverse applications, such as enhanced surface Raman scattering (SERS), antibacterial, and catalysis 1, 5–7.…”
