Selecting target handoff direction message number is necessary and a solvent medium polarity to be considered other. In a conventional dispersing in an aqueous solution containing a hydrophobic polymer material number SDS amphiphilic surfactants are used. SDS dispersing carbon nanotube or carbon black in an aqueous solution which is effective in particular as known. Binary HPLC pump (Waters 1525, USA) on connected series of column 3 (UltrahydrogelTM 1000, 500 and 250 column, Waters, Ireland) aqueous GPC (gel permeation chromatography) index detector (Waters 2414, USA) equipped with a molecular weight of polydispersity index (PDI) and in using SDS is much lower, average molecular weight of less than 20,000 SDS is relatively low but, in the embodiment 1 to 3 dispersion number of average molecular weight min 120,000 or more. In the embodiment 1 to 3 shown in table 2 under the number dispersion prepared by the number of molecular weight and molecular distribution to. In the embodiment 4 To 6 and Comparison example 1 To 2: carbon fiber web number bath Carbon fiber (Torayca, T700SC - 12K, 800 tex) is a fiber cutter (FiDoCut, Fiber Dosing and Cutting system, Schmidt & & Co Heinzmann GmbH. , Germany) using 5 - 6 mm was then cut to length. In the embodiment 1 to 3 dispersion number 0. 3G 3 with carbon fiber. 0G 3000 ml distilled residue such as a sample table 3 have been designated. Magnetic stirrer stirred 1 medium is a continuous time-gate. Device placed on the bottom of dispersed carbon monofilament netting (10 cm × 10 cm) with respect to the deposited. Wire mesh on the as-formed web pulled out of 24 hours in an oven to dry with respect to the 60 °C Comparison example 1 to 2 in the embodiment 4 Figure 2 to 6 carbon fibers and carbon fiber web number morning fair dispersed distilled water are disclosed photograph observing ((a): comparison example 1, (b) in the embodiment 4, in the embodiment 5 (c), (d) in the embodiment 6, comparison example 2 (e)). In the case of number 3 in the embodiment 4 to 6 in the embodiment 1 to dispersion of carbon fiber in aqueous media using comparison example 1 or example 2 using SDS dispersing the controls sample comparison than transmission option. Since dispersion of the present invention is hydrophobic group with a hydrophilic group number have both van der Waal (van der Waals) or electrostatic interaction surface of carbon fiber by the break down is applied by the hydrophilic and carbon fiber can be improve wettability. In addition, dispersion of the present invention is essentially a relatively high number has a nominal molecular weight because carbon fiber can be effectively microcapsules. Such as Peng ("Dispersion Characterization of Short Slag Fiber in Aqueous Solution ." The use of carbon-fiber-fiber of the present invention distributed number divided into stable aqueous dispersions formed individual won help. Figure 3 number of functional groups on the surface of the dispersion of the present invention with the functional groups of the carbon fibers covalently and hydrogen bonds between positions specified by a model is exemplified are disclosed. The surface of the carbon fiber of the present invention linked via hydroxy hydrogen and an epoxy-functional groups distributed number (- COOH, - OH, - CONH, - SO3 H) can be interacts with. This carbon fiber dispersion-based systems on the base. Stop stirring in an aqueous medium of carbon residue in a settling rate immediately after a long time. Monitoring precipitation levels 15, 30, 60, 360 and 720 have recording component, the result is also shown to 4. Figure 4 shows a using time according to precipitation of carbon fiber into different types of dispersion number also indicating graph are disclosed. After a period when the credit card system including carbon fiber of the present invention distributed number precipitation volume has been kept constant. This constant level when distributed number stable CF dispersion forming's oldest. On the contrary, in the case of comparison example 1 and comparison example 2 carbon fiber dispersion stability is poor due to the fiber aggregate system into foods. Nonwoven carbon fiber surface of a digital camera (PL 150, SAMSUNG), optical microscope (CKX41, OLYMPUS, Japan) and field emission scanning electron microscope (FE-a SEM, SU8010, Hitachi, Japan) was irradiated.
