In the view of sustainable development and environment protection, degradable agricultural lms with ondemand thermal insulation properties have attracted growing research interest in the last few decades due to the deteriorating environment and extreme climate on the growth and existence of crops. Here, a general strategy has been developed to fabricate degradable silver nanowires modi ed cellulose (AgNWs/cellulose) hybrid lm with controllable thermal insulation and antibacterial properties by using plant cellulose and AgNWs as building blocks, as well as their agriculture application. The results showed that the AgNWs were evenly dispersed in the three-dimensional grid of cellulose, formed a lm that could withstand a certain tensile force, and have good thermal stability. Due to the excellent electrical conductivity, the AgNWs/cellulose hybrid lms can provide excellent Joule heating, generating rapid thermal response and uniform electrical heating at a low supply voltage of 3 V for extra warmth. In the antibacterial tests against Escherichia coli and Staphylococcus aureus, the AgNWs/cellulose hybrid lm exhibit large diameters of inhibition zones, revealing the high antibacterial activity. Additionally, the AgNWs/cellulose hybrid lms showed highly stretchable behavior by delivering a breaking strain of 1.5% with a tensile stress of 0.45 MPa owing to the cross-linked structures of cellulose and AgNWs. Based on the above properties, this study not only provides a potential strategy for the fabrication of exible and biodegradable agricultural lms but also may provide new insights for agricultural thermal management.
