“…The h-BN at the interface bears most of the stress, which reduces the impact of SEPS on the tensile strength, so it has little effect on the entire system. With the increase of filler content, this method can maintain better mechanical properties than that of a single thermal conductive composite [36]. As the content of h-BN increases, the thermal stability of PE/PP/SEPS/h-BN gradually increases.…”

In this work, the polyethylene (PE) and polypropylene (PP) percentage is controlled at 50:50 to make the composite form a co-continuous structure; the hexagonal boron nitride (h-BN) is wrapped by thermoplastic elastomer styrene-ethylene-propylene-styrene (SEPS). This approach enables the localized distribution of h-BN at the interface of the co-continuous structure of PE/PP/SEPS/h-BN composite material, allowing the construction of a heat conduction path, thereby improving the thermal conductivity of PE/PP. Theoretical calculation predicted the localized distribution of SEPS at the interface of the PE/PP composite co-continuous structure. 2The thermal conductivity of the composites can be improved by 57.7% by adding 10 wt% h-BN, presenting a commercial potential of such composites in heat dissipation applications.

“…Therefore, this article proposes the preparation of PP/SCF thermally conductive composites by multiple ICM method, by adding short carbon fiber (SCF) filler with high thermal conductivity into thermoplastic polypropylene (PP) matrix as thermally conductive filler. 42,43 Based on the above research idea, simulates the molding process of the products through finite element simulation firstly, and simulates the PP/SCF thermally conductive composites with both 20% SCF filler content in injection molding (IM) and injection compression molding (ICM); the orthogonal experimental method and the single-factor analysis method were used to guide the simulation process to obtain the optimal process parameters for IM and ICM, separately. According to the optimal results of the above simulation, three kinds of products by tradition injection molding (IM), multiple injection molding (multiple IM) and multiple injection compression molding (multiple ICM) were prepared respectively.…”

A multiple injection compression molding (ICM) method was proposed on the basis of injection molding and applied for the preparation of polypropylene/ short carbon fiber (PP/SCF) high thermally conductive composites in this article. During each injection compression cycle, the thickness of composite sample would be reduced effectively for better SCF orientation along the flow direction. Moreover, the original loose self-assembled SCF networks obtained from injection process can furtherly transfer into much compact ones under the effect of compression force. The performance differences among SCF/PP composites prepared with one-time injection molding (IM), multiple IM, and multiple ICM were also investigated. The SCF/PP composite sample prepared with multiple ICM method presented superior comprehensive performance, $100% and 28% enhancements in thermal conductivity and tensile strength compared with the one-time IM sample. We believe the multiple ICM method can provide a new idea for industrial production of functional polymer composites, especially for thermoplastic polymer composite.

“…Recently, Qi et al [24] investigated the thermal conductivity of the poly(vinylidene fluoride) composites filled with boron nitride/CNTs. Yang et al [25] experimentally examined the effects of the size, volume fraction and 3-D network organisation of CNTs on the thermal conductivity and thermal stability of CNTs-reinforced composites. More recently, good reviews were provided by Ruan et al [26], Feng et al [27], and Xu et al [28] on the interfacial thermal resistance in thermally conductive polymer composites and the thermal properties, behaviour and performance of polymer-based composites.…”
