“…The rapid advancement of high-precision devices not only requires abnormal thermal expansions but also highly demands multiple functionalities, such as sea-water corrosion resistance, [9] photoluminescence, [18,19] and mechanical properties, [20,21] etc. The integration of abnormal thermal expansions, extremely low thermal conductivity, [22] and sufficient electrical conduction is highly urgent, capable of synergistically resolving critical issues caused by thermal stress, thermal shock, and electrical signal transmission.…”
