In this article, three novel solution‐processable ruthenium‐polymetallaynes (i.e., P1, P2, and P3), in which the redox‐addressable Ru center is covalently embedded into a conjugated organic polymer, are discussed. In pursuit of higher functionality (e.g., stable multistate behavior, low operating voltage), the organic ligand bridging the metal centers is systematically varied. The previously reported P1 has a bithiophene (BT) bridging ligand with a high degree of rotational freedom. By replacing BT with cyclopenta‐dithiophene in P2 and dithieno‐pyrrole (DTP) in P3, both of which are more planar than BT, the degree of freedom is decreased. By using DTP, redox‐matching is achieved between the metal center and organic ligand, leading to extra stability of the mixed‐valence (MV) state in P3. In‐depth experimental (i.e., in situ electron paramagnetic resonance and UV–vis–NIR spectroelectrochemistry) and theoretical studies (i.e., DFT calculations) are carried out on the polymer thin‐films, showing enhanced metal–metal (M–M) interaction in P2 and P3 and stable Robin–Day class III MV compound in P3. These polymers are also first time fabricated into solid‐state electrochromic devices and the stability of each oxidation state is characterized by tracing the change of transmittance over time, showing satisfactory cyclic stability and retention behavior (≈90% retention after 30 min).","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91037353","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, most previously reported devices are fabricated using multiple technical processes—which impede device implementation—while the low‐output current triggered in most such devices limits the possible integration of auxiliary gadgets. Therefore, by spontaneously wrapping a conjugated block copolymer around single‐walled carbon nanotubes (SWCNTs), a thin‐film transistor memory device comprising single‐layered poly(9,9‐dioctylfluorene)‐b‐polyisoprene (PF‐b‐PI)‐wrapped‐SWCNTs—which function as both a semiconductor and an electret layer—to simplify the device structure and fabrication is designed. Owing to the robust SWCNT charge carrier mobility (≈11.3 cm2 V−1 s−1), a high output current (10−4 to 10−3 A) can be achieved and because PF is a photoactive conjugated polymer, the photonic signal can also be modulated. The designed memory device independently exhibits both voltage‐ and light‐controllable switching, thereby mimicking biological synaptic behavior such as short‐ and long‐term plasticity, spike‐time, and spike‐rate‐dependent plasticity. This study may provide a suitable basis for developing more‐convenient, economical, highly versatile synaptic devices.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74431671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, for their widespread use in consumer electronics, innovative and cost‐effective processing methods need to be developed. In this contribution the effectiveness of the deposition of lead zirconate titanate thin films by inkjet printing for the fabrication of haptic devices is demonstrated. The 1,3‐propanediol solvent is used to prepare effective inkjet‐printing inks from chemical solution deposition solutions. The printed thin‐film structures on fused silica glass substrates are 900 nm thick and strongly {100} oriented perovskite phase is detected in X‐ray diffraction patterns. To fabricate devices, interdigitated capacitors and SU‐8 insulation layers are deposited on top of the printed lead zirconate titanate. Dimensions of the final device are 15.7 × 3.4 mm2. A standing antisymmetric Lamb wave is observed at 63.3 kHz, with out‐of‐plane displacement reaching 2 µm at an applied voltage of 100 V. This value exceeds the limit at which the texture rendering function can be induced in the device. Good functional performance of the device is linked with good electromechanical properties of the printed piezoelectric, with permittivity ε ′ and piezoelectric coefficient e33,f values of 1000 and 7.7 C m−2, respectively, which are comparable to films prepared by standard spin‐coating process.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84677157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This drives up demand for electronic materials with excellent process ability and functionality from one‐step molding of microminiature to large‐scale devices. Herein, a novel method is introduced for fabricating high‐performance barium titanate (BaTiO3)‐polydimethylsiloxane composites based on three‐dimensional (3D)‐printing‐ordered structure of a metamaterial skeleton. When subjected to external mechanical stress, the metamaterial structure facilitates effective stress transfer, resulting in a significantly improved voltage output. In comparison to traditional low‐dimensional ceramic polymer composites, metamaterial‐structured BaTiO3 composites exhibit excellent electromechanical energy conversion properties, thereby enabling tactile imitation applications and mechanical energy harvesting.

The laser toner acts as a mask to selectively block the ion exchange self‐metallization (IESM) reduction reaction that forms nanoscale silver or palladium coatings at the polyimide surface. The silver or palladium IESM coating is then used as a catalyst for electroless deposition of copper. Under appropriate conditions, the copper is deposited selectively on top of the catalyst layer. The resulting copper layer has a measured sheet resistance as low as 0.3 Ohms/sq. Electrical isolation is measured between copper traces spaced as close as 300 microns, and high conductivity is measured along traces with widths as low as 200 microns. The minimum pattern size appears to be limited primarily by the resolution of the laser toner pattern, as the IESM metal layer is observed to follow the contours of individual toner particles. The process avoids the use of high temperature, vacuum, and organic solvents and is thus suitable for very low cost prototyping or distributed manufacturing of simple electronic devices.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"56 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83478017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the enhancements to the EDL capacitive response are significantly important challenges for advanced applications with outstanding performances. Herein, an ultra‐sensitive and quick‐responsive hybrid‐supercapacitive iontronic pressure sensor using a novel sensing mechanism and facile fabrication technique is reported to overcome the limitations of the existing iontronic pressure sensors. As a sensing material, conductive polymer and carbon nanotube are incorporated into the iontronic film, as pseudo‐ and EDL‐capacitive material, respectively. Moreover, vinyl silica nanoparticle (VSNP) is used to decrease the recovery time by making the iontronic film quick‐response. The developed hybrid‐supercapacitive pressure sensor exhibited an ultra‐high sensitivity of 301.5 kPa−1 over a wide pressure range of up to 63.3 kPa along with a fast recovery time of ≈32 ms. It is believed that the proposed hybrid‐supercapacitive mechanism in iontronic film will significantly enhance the performance of conventional iontronic pressure sensors.","PeriodicalId":7200,"journal":{"name":"Advanced Materials & Technologies","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87478048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
