For the thermal management of electric devices, the application of phase change materials (PCMs) such as paraffin has been studied. However, as long as the PCM changes to liquid phase, a sealed structure is required, which is a constraint for weight reduction. Therefore, the authors have focused on trans-1,4-polybutadiene (TPBD), a semi-crystalline polymer that accumulates heat by crystal structure transition at 50~80 °C in the solid phase. However, the strength of TPBD is insufficient and thermal conductivity is not enough to dissipate the heat. In this study, a method to homogeneously apply TPBD to the surface of carbon fiber reinforced plastics (CFRP) was developed using cellulose nanofiber (CNF) and aqueous electrodeposition solution containing a polymer with epoxy group. The heat-storable CFRP was obtained, the maximum exoergic and endoergic heats of 30 J/g were confirmed, and its tensile strength was approximately 61% of CFRP without TPBD/CNF.

对于电子设备的热管理，已经研究了相变材料（PCM）（例如石蜡）的应用。然而，只要PCM变为液相，就需要密封结构，这是减轻重量的限制。因此，作者都集中在反1,4-聚丁二烯（TPBD）是一种半结晶聚合物，通过固相在50〜80°C时的晶体结构转变而积聚热量。然而，TPBD的强度不足并且导热率不足以散发热量。在这项研究中，开发了一种使用纤维素纳米纤维（CNF）和含环氧基聚合物的水性电沉积溶液将TPBD均匀地涂在碳纤维增强塑料（CFRP）表面的方法。获得了可热存储的CFRP，确定最大的放热和吸热量为30 J / g，其拉伸强度约为不含TPBD / CNF的CFRP的61％。
