While I-0 (without IBOA) formed a robust, chemically crosslinked network with solid-like behavior, I-40 (with IBOA) exhibited viscoelastic properties indicative of linear or branched chain structures. These differences were traced to pre-curing chain formation dynamics, where the presence of IBOA and its propagation rate resulted in early crosslinking with shorter chains. The findings provide valuable insights into optimizing UV-curing processes and monomer formulations to tailor OCA performance for advanced display applications.</div></div>","PeriodicalId":13732,"journal":{"name":"International Journal of Adhesion and Adhesives","volume":"141 ","pages":"Article 104069"},"PeriodicalIF":3.2,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144170246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Etching was performed for 30 min, 1 h, and 2 h. After elemental analysis (energy-dispersive spectroscopy, EDS), surface roughness (Ra, Rz, Rv, and Rc, RzJIS, Rp) measurements (3D microscopy), two adhesive luting systems (PV: Panavia 21 and ML: Multilink Hybrid Abutment) were bonded onto the conditioned substrates.

Inspired by the remarkable adhesion mechanisms of marine mussels, recent studies have explored biomimetic strategies—such as dual crosslinking, organic-inorganic hybridization, and sacrificial bond mechanisms—to enhance the bonding strength and water resistance of SP-based adhesives. This review examines the effectiveness of these mussel-inspired modifications compared to conventional crosslinking approaches in SP adhesives. Surprisingly, the improvements in adhesive performance, particularly in terms of bonding strength and water resistance, were only marginally superior to those achieved through non-biomimetic modifications. This finding suggests that while mussel-inspired strategies offer valuable insights, further refinement is necessary to fully harness their potential. Specific technical directions, such as designing SP-specific mussel-inspired peptide segments, incorporating catechol-functionalized crosslinkers, and optimizing redox-responsive or pH-sensitive bonding mechanisms, represent promising routes for improvement. By critically evaluating these approaches, this review also highlights opportunities for advancing SP-based adhesives through novel crosslinking techniques, cost-effective formulations, and processing methods.

The W-Mn-Cu-Sn alloy particles were produced via mechanical alloying (MA). MA is a process that involves repeated cycles of cold welding, fracturing, and re-welding of powder particles, producing fine, homogeneous materials with improved properties. This technique plays a vital role in uniformly dispersing particles within the tungsten matrix, thereby enhancing the alloy's mechanical properties. The mean diameters of each sample were determined from statistical analysis of 33 measurements using ImageJ software, resulting in an average diameter of 245 nm. Furthermore, the particle size distribution predominantly ranged from 121 to 439 nm. The crystallographic characteristics of the powders were analyzed using X-ray diffraction (X'Pert PRO, Malvern PANalytical) with CuKα radiation (λ = 0.15406 nm).
