Understanding in crystallization of polyethylene: the role of boron nitride (BN) particles

The authors examine the melting and crystallization behavior of a polyethylene/boron nitride composite to understand an unexpected exothermic peak when the BN content was greater than 10 wt. %. Based on these observations, an optimal annealing temperature of the composite was investigated to enhance its thermal conductivity. The appearance of the peak was determined to depend on the different nucleated capability of the different BN aggregates in local area. An annealing ...

Enhanced thermally conductivity and mechanical properties of polyethylene (PE)/boron nitride (BN) composites through multistage stretching extrusion

This study aimed to enhance the thermal and mechanical properties of polyethylene (PE)/boron nitride (BN) composites by manipulating the BN concentrations in the matrix and by applying shear fields in laminating-multiplying elements (LMEs). A thermal constants analyzer measured the thermal conductivity of the PE/BN composites using the transient plane source (TPS) method. Results showed that the thermal conductivity of the composites increased with BN concentration. As well, the ...

Reinforced thermal conductivity and mechanical properties of in situ microfibrillar composites through multistage stretching extrusion

Various microfibrillar composites were prepared in situ using boron nitride as a thermally conductive filler. The multistage stretching extrusion process was used in an effort to improve thermal conductivity and mechanical properties. It was found that the addition of laminating-multiplying elements (LMEs) improved the dispersion of BN in the composite polymers and they also improved the tensile and impact strength of the polymers. It was also found that the thermal ...
