Crude oil pipeline transportation is one of widely used ways in land transportation and comprises a large share of the world's long-distance oil transmission. Warming and heat preservation of crude oil is vital for efficient oil pipeline transportation. However, it remains a formidable challenge in coping with caused tremendous energy consumption and environmental pollution. In this work, bio-based phase change composites with superior thermal-formability and photothermal storage properties were fabricated and molded to photothermal oil transportation system using template-confined thermoforming strategy. On the basis of desirable thermal energy management ability of PEG as well as the synergistic effects between heat localization and electron nonradiative transition of Fe₂O₃ nanoparticles, the system realized a remarkable decrease in oil viscosity and efficient transmission. Particularly, the preparation process could be facilely scaled up and indicate real application feasibility. This successful exploration offers a significant path for developing green, highly effective crude oil transportation.
