水下搅拌摩擦加工制备碳纳米管增强PE-HD结构与拉伸性能研究
Structure and Tensile Properties of PE-HD/MWCNTs Composites Prepared by Submerged Friction Stir Processing Method
摘要
Abstract
In this paper,we reported the preparation of high-density polyethylene (PE-HD)/multiwalled carbon nanotubes (MWCNTs) composites through a submerged friction stir processing method,and effects of rotation speed and content of MWCNTs on morphologies and properties of the composites was investigated.The results indicated that MWCNTs were homogeneously dispersed in the matrix in the form of a “cloud”.For the case of the composites containing 1 wt ％ and 2 wt ％ of MWCNTs,the tensile strength increased at first and then tended to decrease with an increase of rotational speed.However,the composite containing 4 wt ％ of MWCNTs exhibited a continuous increase in tensile strength with an increase of rotational speed.A differential scanning calorimetric investigation indicated that the degree of crystallinity of PE-HD was reduced with an increase of the content of MWCNTs.关键词
