Typical several strategies including monomer/molecule structure design, aggregation structure regulation and nanocomposite strengthening have acquired numerous processes. However, it is always ignored in existed work that insulation failure of polymer material generally starts from surface, and high-frequency electric field can greatly accelerate this failure process. Here surface modification engineering (SME) on polymer materials with a scalable, rapid and low-cost characteristic presents unique superiority in solving current problems. In this Review, we summarize various SME approaches on polymer materials and discuss introduced variations in surface morphology, physicochemical structure and charge transport behavior. We analyze how particular chemical groups anchoring, organic–inorganic deposition, physicochemical evolution and micro-nano structure design of modification surface can be modulated to obviously enhance multilevel insulation properties (from surface to interior even under high-frequency electric field) and subsequent dielectric energy storage performances. In addition, we highlight the multifunctionality and stability of modification surface on polymer materials, which examines the possibility of synergistically improving other performances like antifouling and anti-corrosion toward complicated/hash insulation scenes and advanced energy storage. Finally, we analyze current challenges in this field and offer a prospect for future development toward high-performance and large-scale practical applications.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 758-823"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720917","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to achieve a long-term steady state of the local biomechanical environment, it is essential to coupling implant degeneration and neo-tissue ingrowth without sacrificing local mechanical integrity. Steroid-associated osteonecrosis (SAON) presents a formidable clinical challenge, necessitating robust mechanical support to prevent collapse of weight-bearing hip joints while reversing pathological progression. Herein, a novel tree-inspired Mg hybrid column (Mg + BC) incorporating cannulated Mg screw and injectable Mg-containing bone cement (BC) is reported. Mg + BC tuned the gradual release of mineral ions (Mg, Ca, P), OH^– and H₂ via electrochemical suppression and crystal re-deposition during degradation. Finite element analysis demonstrated that Mg + BC significantly reduced the proportion of relatively high load-bearing regions (CD: 26.0 %, Mg: 26.6 %, BC: 18.2 %, Mg + BC: 17.5 %) and effectively shifted the predominant loading from subchondral trabeculae to the femoral shaft cortex. The efficacy of the tree-inspired Mg hybrid column was validated in a clinically relevant bipedal emu model of SAON. Compared to standalone Mg screws, Mg + BC exhibited sustained degradation and enhanced bone-implant contact, indicating improved alignment between material degradation and tissue regeneration. After 6 months <em>in vivo</em>, the implant residue volume was significantly higher in the Mg + BC group (73.53 ± 10.90 %) compared to the Mg screw group (39.10 ± 11.31 %). The optimized degradation pattern of Mg + BC facilitated bone regeneration through modulation of macrophage recruitment and M1-to-M2 polarization shift. Notably, Mg + BC treatment significantly reduced hip joint collapse incidence (1/10) compared to CD group (7/10). The Mg + BC group maintained greater articular cartilage thickness in the intact region (1.74 ± 0.25 mm) compared to CD group (0.71 ± 0.15 mm). Gait analysis revealed substantial improvement in stride length for the Mg + BC group (87.14 ± 2.29 cm) compared to CD group (60.03 ± 1.31 cm), indicating maintenance of the hip anatomical structure and functional performance. Taken together, the tree-inspired Mg hybrid column is expected to be a unique hybrid system for bone tissue regeneration and prevention of joint collapse in weight-bearing regions affected by SAON, offering promising translational potential for clinical application.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"80 ","pages":"Pages 113-138"},"PeriodicalIF":21.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142720924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, bottom-up growth of high-quality bismuth oxychloride twisted homostructures (BiOCl THS) is achieved by a precursor-regulated chemical vapor deposition (CVD) method. In contrast to the conventional screw-dislocation-driven growth of spiral-like nanosheets, the as-prepared BiOCl THSs show a wide range of twist angles and large lateral sizes. A unique secondary twisted nucleation growth mechanism is revealed by multiple characterizations and theoretical calculations. It is demonstrated that the adsorption of polar H₂O molecule on BiOCl can lead to a stable nucleation with rotation angles. Furthermore, benefitting from the bottom-up growth of the twisted homostructures, clear moiré patterns and moiré potential induced variation of interlayer coupling and exciton resonances were observed in the BiOCl THS.
