Initial Capacity

The SiOx/Si composite enhanced by dual-carbon (i.e., multiwall carbon nanotubes and carbon) was fabricated from the micro silicon monoxide (SiO) by the combination of high-energy mechanical milling, spray drying and pyrolysis. The obtained SiOx/Si particles were composed of Si-suboxide and embedded nano-sized Si crystallites. As one of dual-carbons, the multi-walled carbon nanotubes were directly scaffolded of anchoring the SiOx/Si composite particles through spray drying. Another carbon source was directly deposited on the surface of the SiOx/Si by means of the carbonization of phenol–formaldehyde resin. Nano-sized silicon embedded in the Si-suboxide matrix and dual-carbon provided a compromise between the reversible capacity and cycle stability related to the volume change. The obtained SiOx/Si/MWCNT/PC-1 electrode delivered an initial capacity of 936.5[Formula: see text]mAh g[Formula: see text] and the reversible capacity was maintained at 825.9[Formula: see text]mAh g[Formula: see text] with excellent capacity retention of 87.5% on the 200th cycle versus the 6th one (compared with the same current rate). In contrast, although the SiOx/Si presented the higher initial capacity of 1271.4[Formula: see text]mAh g[Formula: see text], its capacity dropped quickly after several cycles and capacity retention was only 25.6% versus the 6th cycle after 100 cycles.

Thermal Conductivities

In this article, in order to improve the thermal conductivities and mechanical properties of EPDM filled with carbon nanotubes, phenol formaldehyde resin is used to coat to the surface of carbon nanotubes so as to improve the dispersion in rubber matrix and the combination with EPDM. The results show that with the ratio of CNTs and PF increased, the thermal conductivities of carbon nanotubes/EPDM composites show upward trend. Besides, with the increase of filler content, thermal conductivities of composites are improved as well. However, the mechanical properties of composites are declined. Therefore, more effective methods of modification of carbon nanotubes should be attempted, and more experiments should be conducted to improve mechanical properties of filled EPDM and ensure the high thermal conductivities at the same time.

Utilizing synergetic effects of different fillers was an important strategy to develop high-performance polymer nanocomposites. In this work, novel hybrid nanofillers composed of graphene oxide (GO) and alkali lignin (L) were obtained successfully, and their reinforcing effect of phenol formaldehyde (PF) resin was fully investigated. The structures, morphologies, and properties of the GO-L nanocomposites were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron microscope, thermal gravimetry analysis, and Raman spectra. Dynamic mechanical analysis results showed that the GO-L–reinforced PF resin is much better than the single added GO and lignin with the same weight ratio. The effect of the filling ratio of GO-L on the storage modulus of PF was also investigated. Results showed that the storage modulus of PF was increased from 2015 MPa to 3675 MPa with the addition of 2 wt% of GO-L (3:7) hybrids.
