A composite adsorbent coating on Al6061 aluminum substrate, based on SAPO34 zeolite filler and sulfonate poly (ether-ether ketone) (S-PEEK) matrix is proposed for sustainable energy saving technologies. The effect of sulfonation degree on the mechanical and physical chemical properties of the composite coating was assessed by synthesizing four batches with a degree of sulfonation of the matrix ranging from about 40%–50%. The degree of sulfonation was measured by titration and confirmed by thermogravimetry and FTIR analysis. For each batch of S-PEEK four coatings at increasing SAPO-34 filler content (in the range 80−95 wt.%) were realized. The composite coatings were homogenous and almost defect free. The mechanical performances, evaluated by scratch and pull-off tests, highlighted that all batches exhibited a suitable behavior for adsorption heat pumps application in mobile systems. Best results were observed by using a relatively high sulfonation time of S-PEEK. Obtained coating exhibited indeed very good adhesive and cohesive properties as well as high water vapor uptakes.

提出了一种基于SAPO34沸石填料和磺酸盐聚醚醚酮（S-PEEK）基体的Al6061铝基复合吸附涂层，以实现可持续的节能技术。通过合成四批基质的磺化度约为40％–50％，评估了磺化度对复合涂层机械和物理化学性能的影响。通过滴定测量磺化度，并通过热重分析和FTIR分析确认。对于每批S-PEEK，实现了以增加的SAPO-34填料含量（在80-95 wt。％范围内）的四种涂层。复合涂层是均匀的，几乎没有缺陷。机械性能，通过刮擦和拉拔测试进行评估，强调指出，所有批次都表现出适合移动系统中吸附热泵应用的性能。使用相对较高的S-PEEK磺化时间可观察到最佳结果。所获得的涂层确实表现出非常好的粘合性和内聚性以及高的水蒸气吸收率。
