Safety issues arising from inefficient heat dissipation in energetic materials demand innovative thermal management strategies. Herein, we proposed a strategy for guiding the design of energetic composite materials with enhanced thermal conductivity based on molecular dynamics simulations and density functional theory. Based on this strategy, suitable fillers for improving the thermal conductivity of different kinds of energetic materials could be quickly selected and a way to further balance the thermal conductivity and filler content could be figured out. Results showed that hexagonal boron nitride nanosheets (h-BNNSs) are suitable fillers, which can improve the thermal conductivity of the well-known energetic material 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane (HMX) by about 8.16%, and this could be further increased to 30.48% by doubling the amount of h-BNNSs. More importantly, the thermal conductivity of HMX can be enhanced substantially by adjusting the interfacial interactions between fillers and energetic materials without doubling the amount of h-BNNS. This improvement is achieved by using hydroxylated h-BNNSs (h-BNNSs-OH) as the filler, which greatly strengthens interfacial interactions through hydrogen bonding, reduces interfacial thermal resistance, and facilitates phonon transport. This work may provide insights into the development of an atomic-scale design strategy for thermally stable energetic materials through synergistic interfacial chemistry and phonon engineering.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant heat.

Thermal Sigmatropic Reactions: Overview
Sigmatropic shifts are classified based on an order term [i, j ], where i and j indicate the number of atoms across which each end of the σ bond migrates. Below are examples of a [3,3] sigmatropic shift in 1,5-hexadiene, referred to as...
