Foams that mix seemingly reverse properties, similar to excessive thermal insulation and electrical conductivity, are extremely wanted for modern-day superior purposes. Nevertheless, attaining a stability of those properties necessitates cautious tuning of fabric compositions. Right here, we ready ice-templated Ti3C2Tx-alginate composite foams and investigated the function of Ti3C2Tx MXene in triboelectric vitality manufacturing, thermal insulation, and flame retardancy. Our outcomes present that including 5 wt% Ti3C2Tx enhances the triboelectric output of 6 mm thick foams (380 V, 7.7 μA, 43 mW m−2) by 110%. Regardless of incorporating electrically conducting Ti3C2Tx, these macroporous composite foams have a thermal conductivity of solely 62 mW m−1 Okay−1, whereas additionally they present flame-retardant properties, exhibiting self-extinguishing habits. Lastly, we display these composite foams for establishing good fireplace alarm programs as they reply to small modifications in electrical resistance induced by fireplace. Our findings show that Ti3C2Tx is a flexible filler for biopolymer foams, introducing complementary functionalities that may be exploited in vitality and security purposes.
