Twisted graphene possesses unique electronic properties and applications, which have been studied extensively. Recently, the phonon properties of twisted graphene have received a great deal of attention. To the best of our knowledge, thermal transports in twisted graphene have been investigated little to date. Here, we study perpendicular and parallel transports in twisted few-layer graphene (T-FLG). It is found that perpendicular and parallel transports are both sensitive to the rotation angle theta between layers. When q increases from 0 degrees to 60 degrees, perpendicular thermal conductivity kappa(perpendicular to) first decreases and then increases, and the transition angle is theta = 30 degrees. For the parallel transport, the relation between thermal conductivity kappa(parallel to) and theta is complicated, because intra-layer thermal transport is more sensitive to the edge of layer than their stacking forms. However, the dependence of interlayer scattering on theta is similar to that of kappa(perpendicular to). In addition, the effect of layer number on the thermal transport is discussed. Our results may provide references for designing the devices of thermal insulation and thermal management based on graphene.
