Conventional photolithography encounters significant challenges in the micro-/nano-fabrication of polymeric materials due to insufficient chemical orthogonality with photoresists. Emerging methodologies, including inkjet printing, meniscus-guided coating, and innovative lithography techniques, have partially mitigated these issues but still frequently encounter limitations related to material versatility and process complexity. In response to these challenges, we developed the nano-aluminum micro-pattern infusion (NAMP-I) technique, which enables the precise patterning of solution-processed organic OSC films on hydrophobic perfluoro(1-butenylvinylether) polymer (CYTOP) dielectric layers. This innovative method employs aluminum-nanoparticle metal films to initiate and control OSC growth, thereby enhancing interfacial quality through the formation of aluminum oxide (Al<sub>2</sub>O<sub>3</sub>) and improved hydrogen bonding interactions.

The current study develops a type of TPAE with SME by fabricating the long carbon chain polyamide (PA512) and polyethylene glycol (PEG) through a two-step melt polycondensation process. The properties of TPAEs were investigated by varying the PA512 prepolymer’s molecular weight and the amount of PEG. During synthesizing TPAEs with SME, the crucial balance of COOH and OH groups was skillfully achieved by introducing biobased butanediol (BDO). The chemical structure of TPAEs is confirmed by FTIR and <sup>1</sup>H NMR tests. By meticulously engineering the PA512 molecular weight and refining the PEG domain content, TPAEs are fabricated to elongate at a break of 592.4% at room temperature while maintaining a tensile strength of 23.1 MPa. TPAEs, which have two distinct melting temperatures, exhibit microphase separation between the PEG and PA512 domains. This phenomenon is further corroborated by the scanning electron microscope (SEM) test. Additionally, TPAEs exhibit the SME, which can fix a temporary shape when heated, twisted, and cooled, and then recover to its original shape upon reheating, with TPAE230 demonstrating the most outstanding shape memory effect, achieving an average shape fixity ratio of 91.2% and a shape recovery ratio of 94.4%. This behavior is attributed to the fixing force provided by the PEG domains and the entropy elasticity of the physically cross-linked PA512 domains. The findings indicate that TPAEs exhibit enhanced SME in response to temperature changes. Leveraging this property, developing a temperature-sensitive device holds promise for breakthroughs in elastic temperature sensing applications.</p></div>","PeriodicalId":7220,"journal":{"name":"Advanced Composites and Hybrid Materials","volume":"7 6","pages":""},"PeriodicalIF":23.2,"publicationDate":"2024-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
