Conducting and stretchable emulsion styrene butadiene rubber composites using SiO2@Ag core-shell particles and polydopamine coated carbon nanotubes

Enhancement of dielectric properties of acrylic resin elastomer‐based composites with SiO2 loaded carbon nanotubes

“…15 In addition, several new peaks have been found in SiO 2 @CNT, with absorption peaks at 1070, 962, 873, and 454 cm À1 are attributed to the asymmetric stretching vibration of the Si O Si group, the mixed vibration of the Si O group, the symmetric stretching vibration of Si O Si group and the mixed vibration mode of Si O Si group, respectively. 16,17 The appearance of these characteristic peaks further confirms the successful loading of SiO 2 on the CNT surface.…”

“…However, the OH absorption peaks at 3436 and 1636 cm −1 in the FT‐IR spectrum of SiO 2 @CNT show a significant redshift, which is possibly explained by the SiOH vibrations on the surface of the prepared SiO 2 nanoparticles 15 .

Enhanced dielectric and mechanical properties of polylactic acid/polycaprolactone blends by introducing double‐layer carbon nanofillers

“…However, although PDA can improve the dispersion of fillers, the introduction of rigid particles with increasing Ni‐CNTs and Ni‐GRAs can lead to internal defects and stress concentration. Secondly, Ni‐CNTs and Ni‐GRAs act as nucleating agents for PLA and PCL, increasing crystallinity (Figure 6 and Table 1) and reducing elongation at break 31 . The better enhancement provided by Ni‐GRAs compared to Ni‐CNTs is caused by isotropic orientation, and Ni‐GRAs planes can transfer mechanical loads in two dimensions 32 .…”

Fluorinated Polydopamine Shell Decorated Fillers in Polytetrafluoroethylene Composite for Achieving Highly Reduced Coefficient of Thermal Expansion

“…The characteristic peaks of stretching vibration and flexural vibrations of O−Si−O bonds can also be detected separately at 1104 cm −1 , 803 cm −1 , and 475 cm −1[14,15]. The observed peak at 1619 cm −1 in the curve of D-SiO2 originates from the shear vibration of amine group (−NH2) in PDA molecule chains[16]. All the characteristic peaks of BC-D-SiO2 and PFBC-D-SiO2 shifted to high-energy regions compared to those of D-SiO2.…”
