In this work, nitrile butadiene rubber (NBR)/chloroprene rubber (CR) blends were prepared and investigated. The results showed that NBR and CR in the NBR/CR (50/50) blend were partially compatible. This blend had a relatively regular and compact structure, which improved the mechanical properties as well as the weather resistance, thermal stability, and oil, grease resistances. At the DLH compatibilizer content of 1% (made from Cashew nut shell liquid) or D01 (made from Tung oil), the materials possess better mechanical and physical properties due to much more regular and compact structure. NBR/CR blends can be potential materials for industrial applications which demand high oil and grease resistance and good weather resistance as well as good thermal stability.

Carbon nanotubes are used in applications such as energy storages, electronic devices. For these applications, direct assembly of the well aligned and densely packed CNTs (VACNTs) on electrically conducting substrates is of interest. In this paper, we report a direct growth of the VACNTs on several substrates by using hot-filament chemical vapor deposition (hot-filament CVD) and a catalytic buffer-layer structure. The buffer layer was the Aluminum (Al) thin film used together with iron (Fe) as the catalyst. It was found that the underneath layer (Al) was critical for obtaining the VACNT forests with high purity and good contact. The as-fabricated VACNT/support-material structures are object to test field electron emission properties. Testing results of the VACNT samples demonstrated promising field emission characteristics in term of high emitting currents.
