Brief Introduction to Results

Rational utilization and recycling of multiple energy sources is an effective way to solve the energy shortage and environmental pollution crisis. In this paper, Heng Xie and other researchers at Huazhong University of Science and Technology published a paper in the journal "ACS Nano" titled "Bioinspired Micro/Nanostructured Polyethylene/Poly (Ethylene Oxide)/Graphene Films with Robust Superhydrophobicity and Excellent Antireflectivity for Solar - Thermal Power Generation, Thermal Management, and Afterheat Utilization". The research proposes an industrialized polymer molding technology combining melt blending and compression molding - micro-extrusion compression molding technology for mass production of bio-inspired micro/nano-structured polyethylene/polyoxyethane/graphene (MN-PPG) films.

Since polyethylene oxide and polyethylene form a co-continuous network, MN-PPG films have good shape stability, high energy storage density and excellent thermal management capabilities.

Summary

In summary, the surface of MN-PPG8 film exhibits good static, dynamic superhydrophobicity, excellent acid and alkali resistance and heat resistance, passive anti-icing and active de-icing performance, which is conducive to service life and reliability in harsh environments.

Finally, a multi-functional energy collection and circulation system composed of MN-PPG8 thin film, thermoelectric module and LED chip is established to achieve all-weather energy collection and circulation.

As a technique for large-scale production of multifunctional MN-PPG thin films, this method provides an avenue for the development of all-weather energy harvesting materials and systems.
