The foaming agent alkyl polyglucoside was added into graphene oxide dispersion to generate graphene oxide microbubble agglomerates, which were then combined with polyurethane sponge skeleton through impregnating, the as-obtained composite sponge was rapidly frozen in liquid nitrogen and reduced by hydrazine vapor to form the reduced graphene oxide/polyurethane composite sponge with special three-dimensional hierarchical porous structure as well as superhydrophobicity and flexible piezoresistive sensing performance. The results show that the reduced graphene oxide/polyurethane composite sponge-based flexible stress-strain sensor has a sensitivity of up to 3.8(gauge factor, GF), a response time as low as 45 ms. In addition, reduced graphene oxide/polyurethane composite sponge has good superhydrophobicity with water contact angle(WCA) up to 152.5°, which has potential application in the complex environment such as wet and underwater.
