Prepartion And Performance Of Waterborne Polyurethane/Graphene/Carbon Nanotubes Nanocomposites Material

Waterborne polyurethane (WPU) is a superior performance polymer materials withown unique properties such as wear resistance, chemical resistance, good flexibility, highadhesion, low film formation temperature, etc.. It gets a wide range of applications inmany fields, such as aviation, vehicles, machinery, civil construction, light industry,textile, leather and other industries. But there are many own shortcomings of waterbornepolyurethane, such as washing, solvent resistance, and mechanical properties are alsoflawed, its application is subject to certain restrictions, in order to get some improvementwaterborne polyurethane, we should change sex for polyurethane waterborne useNanomaterials.Carbon nanotubes (CNTs) has a great surface area, aspect ratio and inert surface, it iseasy to reunite. This nature is detrimental to their uniformly dispersed and excellentperformance in the polymer. After the chemical modification of carbon nanotubes on itssurface, carbon nanotubes will have a large number of active groups, in favor ofimproving the dispersibility of carbon nanotubes in the matrix. Graphene with a lot ofgood properties of graphite and carbon nanotubes are considered new high-performancenano-reinforcements, also brings many performance improvements for polymercomposites and expands its field of application.In this paper, the CNTs and Graphene will be treated through the experiment both asa filler composited with WPU, we will discuss different ratios of Graphene and CNTscomposited with waterborne polyurethane and the improvement of mechanical, thermal,electrical properties. The coordinating role of the CNTs and Graphene greatly improve theconductivity, optical and other properties of the composites.We have gotten characterized and analysis by FTIR, SEM, DSC, TG and Raman andother testing methods for product, it showed that, when the ratio of Graphene and CNTs is2:1, a composite film obtained works best. The modified Graphene and CNTs by couplingNot only in water has good dispersion, but also agglomeration in the composite material isalso reduced; Graphene and CNTs special structure, amino coupling agent as a goodbridge, in under the effect of a covalent bond, WPU and Graphene composited with CNTs and improved the thermal stability and the mechanical properties of WPU.
