Properties study of composites for polybutene‐1 and modified graphene oxide

Polybutene‐1 (PB‐1) was wildly used as pipe and film with its excellent mechanical performance, great creep resistance even at high temperature, good machinability, and fillable performance. This work focused on studying the properties of composites for polybutene‐1 and modified graphene oxide (MGO)...

Description
Summary:Polybutene‐1 (PB‐1) was wildly used as pipe and film with its excellent mechanical performance, great creep resistance even at high temperature, good machinability, and fillable performance. This work focused on studying the properties of composites for polybutene‐1 and modified graphene oxide (MGO). The graphene oxide (GO) was prepared using an improved Hummers method, and then it was modified with γ‐methylacryloxy propyl trimethoxysilane (KH570). After that, the obtained MGO was composited with PB‐1 by the solution blending method. The structure and properties of PB‐1 composites were investigated by Fourier transform infrared (FTIR), scanning electron microscope (SEM), X‐ray diffraction (XRD), thermogravimetric analysis (TGA), differential scanning calorimeter (DSC), universal material testing machine. The results showed that the MGO and PB‐1 presented good compatibility, and the addition of MGO could not change the crystal morphology of PB‐1. When the content of MGO was 0.75 wt% of PB‐1, the melt and crystallization temperatures were 127.5 and 70.5°C, and the strength of tensile and bending in the PB‐1/MGO composites was 27.58 and 674 MPa. Thus, the PB‐1/MGO composites have great potential for practical applications, such as in agricultural films and tubes.
