Conventional strategies aimed at enhancing breakdown strength typically lead to a concomitant deterioration in tear strength, creating a critical trade-off. Herein, we report robust bilayer-structured composite papers fabricated by integrating a high-concentration poly(m-phenylene isophthalamide) (PMIA) wet film with meta-aramid paper. Through a tailored pressing process, the PMIA not only infiltrates the internal pores of meta-aramid paper but also forms a dense surface layer that substantially reduces structural defects. Benefiting from the formation of multi-scale interfaces and hydrogen-bond networks, the bilayer composite papers exhibit improved tensile strength and tear strength over a broad temperature range. Furthermore, the optimized bilayer composite paper achieves a breakdown strength of 58.4 MV/m at room temperature (RT) and 51.4 MV/m at 120 °C, representing enhancements of 102% and 89.9%, respectively, compared with that of conventional meta-aramid paper. Finite element simulations further reveal that the PMIA layer acts as an effective barrier against electrical tree propagation, thereby delaying dielectric failure. This simple and scalable strategy effectively attenuates the deterioration of tear strength generally associated with enhancing breakdown strength, thus mitigating the severe trade‑off typically observed in other modification routes with reduced loss of tear strength while improving breakdown strength, offering a promising avenue for the development of next-generation advanced insulating materials.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"27 11","pages":"5681 - 5692"},"PeriodicalIF":3.1,"publicationDate":"2026-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176765","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This binder-free and current-collector-free configuration highlights the intrinsic lithium-storage capability of CNTFs and establishes a distinct strategy for developing lightweight and structurally integrated anodes. In this study, the effect of CNT alignment on interfacial behavior is examined by comparing unidirectional (UD) and bidirectional (BD) CNTF structures. The UD-CNTF exhibits a lower initial defect ratio (<i>I</i><sub>D</sub>/<i>I</i><sub>G</sub> = 0.60) than the BD-CNTF (<i>I</i><sub>D</sub>/<i>I</i><sub>G</sub> = 0.89), which promotes the formation of a more uniform and stable solid electrolyte interphase (SEI). In contrast, the higher defect density of the BD-CNTF intensifies electrolyte decomposition, resulting in an excessively thick and resistive SEI layer. Electrochemical impedance spectroscopy (EIS) further confirms that the BD-CNTF exhibits substantially higher interfacial impedance, indicating less efficient charge-transfer kinetics. Consequently, the UD-CNTF delivers superior capacity retention and cycling stability. These results demonstrate that CNT alignment governs defect-mediated SEI formation and interfacial charge transport, thereby providing a mechanistic basis for optimizing free-standing CNTF anodes that operate without conventional active materials.</p></div>","PeriodicalId":557,"journal":{"name":"Fibers and Polymers","volume":"27 11","pages":"5671 - 5680"},"PeriodicalIF":3.1,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149176366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
