Multi-walled carbon nanotubes (MWCNTs) having a high strength, high elasticity and excellent electrical conductivity and thermal conductivity, the reinforcing material is a good natural rubber (NR), and because of its high aspect ratio, agglomerates, it is difficult and NR matrix combination. Before the traditional \higher dispersion efficiency, economic and environmentally friendly the latex blend \Ordinary \Therefore, how to simplify the process and get a good reinforcement effect is urgently needed to solve the problem. The self-assembly is one of the methods of preparation of high-performance natural rubber composite MWCNTs surface modified to avoid complex to simplify the process to obtain a good dispersion, and thus play a reinforcing role. In this paper, step 2 of the latex state electrostatic self-assembly method MWCNTs with NR by static electricity, spontaneous combination associated with the formation of orderly close overall NR / MWCNTs composite and infrared spectroscopy, transmission electron microscopy (TEM), scanning electron microscopy (SEM), dynamic mechanical thermal analysis, thermogravimetric analysis, tensile mechanical properties analysis, crosslink density and Zeta potential - particle size analysis to study the performance of MWCNTs NR / MWCNTs composite. The results showed that the unmodified MWCNTs (U-MWCNTs) in the latex showing no rules aggregate structure modified MWCNTs (MWCNTs-PDDA), and self-assembled to form a stable single-dispersed in the latex and regularly wrapped around the latex particles or latex particles dispersed in between. Composite material, the dispersibility and the compatibility of the base body in the U-MWCNTs, agglomerated together; when the MWCNTs-PDDA content of not more than 3wt%, the interface between fuzzy MWCNTs with-of PDDA with NR, and the compatibility of the base body greatly improved. MWCNTs as an inorganic filler by adding NR, NR / MWCNTs with the elastic modulus of the composite material is increased, the glass transition temperature increases, the rigidity of the material is increased, and compared with the pre-vulcanized rubber, the tensile strength of the composite material greatly improved MWCNTs-PDDA content of 2wt%, reaching a maximum value (31.4 MPa), and played a good role in reinforcing the NR material. MWCNTs in the lamellar structure and the electron conjugated effect, it has a special electrical properties, therefore, through a specific dispersion process makes MWCNTs passage formed in a NR matrix, whether conductive rubber, but also the need for further research . In this paper, prepared by the research \lay the foundation for the industrial production of natural rubber nanotube technology.
