Abstract
The feasibility of using the cryogenic ball-milling process as an environmentally friendly method to produce polymer/CNT nanocomposites was investigated. Linear Low density Polyethylene was used as the matrix material, and 1wt % of Multi-walled carbon nanotubes was used as reinforcement; the influence of the milling time and balls size was evaluated. The morphology of the nanocomposite, and the degree of dispersion of the MWCNTs were studied using SEM, visual inspection and light transmission microscopy; ropes as well as aggregates of MWCNTs were observed, and wetting of the nanotubes by the matrix was also evidenced. An increase of up to 28% in the elastic modulus (determined by tensile testing) with respect to the matrix, was obtained. DSC analysis showed evidence of increase in the degree of crystallization, a result of the nucleating capability of the CNTs in the matrix.
