“…20 Basically the executions of these methods were accompanied with high power of accelerator and pressures, which make it more difficult to perform the process. 15,16,22 Moreover, within some specific processes, the elevated temperature may destroy the unique structure of CNTs during the fluorination process. It has been reported the substantial disintegration of SWCNTs are observed when they are fluorinated at 400 C. 13 Another report also showed that the tubular structure of MWCNTs was destroyed at higher temperatures than 500 C. 19 Based on the existent problems, considering that the decomposition of polytetrafluoroethylene (PTFE) generates only fluorine gaseous products, 23,24 which can be used as fluorination agents for the nanofillers, we propose that to achieve the surface modification of the nanofillers, utilizing the decomposition products of PTFE may be a promising way without directly employing toxic elemental fluorine gas, high power accelerator or high pressure.…”

A facile method for surface modification of nanofillers was developed in order to improve interfacial interaction and dispersion within poly (vinylidene fluoride) (PVDF) matrix. Rather than using the more conventional toxic fluorine gas method of treating nanofillers, a new method of depositing a fluorination coating from decomposition of polytetrafluoroethylene (PTFE) on a carbon nanofiber (CNF) surface was developed. The primary process parameters such as CNF/PTFE ratios and processing temperatures were studied through FTIR and morphological analysis. The fluorination coated CNFs (f-CNFs) were prepared successfully under the conditions of the CNF/PTFE ratio of 1 : 5 at 460 C. The morphological evidence showed that the enhanced dispersion of the f-CNFs and interfacial bonding with PVDF matrix were efficiently induced by the easily manipulated surface modification method. The coating effect for the CNFs was also clearly demonstrated from the electrical conductivity results by comparison of the nanocomposites with f-CNFs and as-received CNFs. Dynamic mechanical analysis results indicated that due to the surface coating on the CNFs, the contribution of the f-CNFs to the storage modulus was dramatically increased from $120 MPa to 1000 MPa at À90 C, an increase by a factor of about 8 times. This study confirmed that the new surface coating method provides a simpler way for practical modification of nanofillers, i.e. through decompositions of polymers, for treatment of nanofillers.

“…The low beam current and short time of irradiation is typically used for passive diagnostics [3,4]. The active methods can give a more detailed distribution of the current density in the cross section [5]. It is the reason for new R&D approaches in the design and the algorithms of active methods.…”

The concept of a real-time profilometer for ion beam is considered in this paper. The profilometer hardware is based on X-Y collector electrodes and the software based on LabVIEW from National Instruments. The software algorithm allows for statistical analysis and the visualization of beam current distribution. The concept of the profilometer was tested on the isochronous Eclipse Cyclotron produced by Siemens.
