摘要

随着对可持续储氢解决方案需求的增加，增强IV型储氢罐中聚合物衬垫和碳纤维增强聚合物（CFRP）之间的粘合界面对于确保储氢罐的完整性和安全性至关重要。研究了等离子体处理对聚乙烯（PE）和聚乙烯/石墨烯纳米片（GNP）复合材料的影响，以优化其与CFRP的结合，模拟了氢罐中的内衬-CFRP界面。首先，评估了等离子体处理对PE表面的影响，重点关注等离子体能量和暴露时间，并对关键的表面修饰进行了表征，并评估了粘合性能。随着GNP含量的增加，对PE/GNP复合材料进行了等离子体处理，比较了未经处理和等离子体处理的样品的结合效率。楔形剥离试验表明，等离子体处理显著增强了PE-CFRP粘合，在510 W和180 s的最佳条件下，楔形剥离强度和断裂能分别提高了212%和165%。0.75 wt.% GNP的等离子体处理PE/GNP复合材料与CFRP的结合明显增强，与未经处理的纯PE-CFRP样品相比，强度和断裂能分别提高了528%和269%。这些发现为提高储氢罐的机械性能提供了实际意义，有助于建立更安全、更高效的储氢系统，实现可持续能源的未来。

Optimization of interfacial bonding between graphene-enhanced polyethylene liners and CFRP composites using plasma treatment for hydrogen storage applications

As the need for sustainable hydrogen storage solutions increases, enhancing the bonding interface between polymer liners and carbon fiber-reinforced polymer (CFRP) in Type IV hydrogen tanks is essential to ensure tank integrity and safety. This study investigates the effect of plasma treatment on polyethylene (PE) and PE/graphene nanoplatelets (GNP) composites to optimize bonding with CFRP, simulating the liner-CFRP interface in hydrogen tanks. Initially, plasma treatment effects on PE surfaces were assessed, focusing on plasma energy and exposure time, with key surface modifications characterized and bonding performance being evaluated. Plasma treatment on PE/GNP composites, with increasing GNP content, was then examined, comparing the bonding effectiveness of untreated and plasma-treated samples. Wedge peel tests revealed that plasma treatment significantly enhanced PE-CFRP bonding, with optimal conditions at 510 W and 180 s resulting in 212 % and 165 % increases in the wedge peel strength and fracture energy, respectively. Plasma-treated PE/GNP composites with 0.75 wt.% GNP achieved a notable bonding enhancement with CFRP, showing 528 % and 269 % improvements in strength and fracture energy over untreated neat PE-CFRP samples. These findings offer practical implications for improving the mechanical performance of hydrogen storage tanks, contributing to safer and more efficient hydrogen storage systems for a sustainable energy future.
