A theoretical strain transfer analysis between the optic fiber, packaging layer, and host matrix to consider the creep effect of the host matrix was performed accordingly for long-term strain monitoring. Parametric studies were carried out using numerical analysis for FBG sensors packaged with glass fiber reinforced plastic (GFRP), also known as FBG-GFRP sensors in concrete, as an example. The results show that embedded in a creep medium, an acceptable long-term performance of packaged FBG sensors requires the packaging layer to have a minimum length and maximum thickness. Laboratory long-term creep tests using epoxy resin and concrete as host matrix for FBG-GFRP sensors also clearly demonstrated that the influence of creep effect cannot be ignored for strain measurements if the host matrix has a creep potential and the developed correction model performed well to reduce measurement errors of such sensors in creep medium.","PeriodicalId":48516,"journal":{"name":"International Journal of Smart and Nano Materials","volume":"13 1","pages":"42 - 63"},"PeriodicalIF":3.9,"publicationDate":"2022-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45276801","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}

In this study, we designed a three-dimensional (3D) lightweight meta-architecture consisting of 6-connected anti-chiral honeycombs. The mechanical properties (e.g. Young’s modulus, compression strength, and Poisson’s ratio) of the proposed meta-architecture could be programmed by adjusting a series of geometric parameters, as shown through numerical simulations. Moreover, an optically sensitive polymer-based 3D meta-architecture with 6-connected anti-chiral features was constructed by the stereolithography method. Owing to the regulation of the negative Poisson’s ratio, 3D meta-architecture achieved a greater ductility under compression than those of traditional truss structures while retaining a relatively high strength and low density. Compression experiments validated the excellent tunability of the mechanical properties of the proposed 3D 6-connected anti-chiral structure.

TPS and compatibilized PLA/TPS were tailored in the first step. The starch with D-sorbitol as a plasticizer was mingled through the internal mixer. Afterward, the maleination method was utilized on PLA to ameliorate the compatibilization of PLA and TPS. In this regard, maleic anhydrate (MA) has been grafted on PLA in the presence of L101 as a peroxide initiator via melt mixing to obtain PLA-g-MA. The optimum content of PLA-g-MA was about 4 phr, confirmed by DMTA and SEM. Noteworthy, the presence of PLA-g-MA has moderately improved the oxygen barrier. Then, the nanocomposites of PLA and TPS containing 1% of Cloisite-30B as well as the optimum compatibilizer (4phr), were produced by melt mixing in the masterbatch module leading to the formation of an extraordinary well-dispersed structure according to XRD patterns. The mixing order controlled the localization of nanosheets. It was concluded that the inclusion of 1% nanoclay in the PLA phase reduces the oxygen permeability by 55% compared to the pristine blend due to the tortuosity effect of nanosheets that are appropriately dispersed in the matrix.

Different from the reported structures, the present metamaterial is designed by constructing repeated lattice microstructure consisting of curved ligaments incorporating hydrogel active layers and polymer support layers and straight polymer bars. When immersed in the solution environment, the swelling of hydrogel layer of such composite structure induces the reversed bending of the ligament, leading to the overall ultra-large shrink (negative expansion) deformation of the metamaterial. Through the new structural design, large NHE effects can be achieved. The theoretical investigation and finite element analysis (FEA) were conducted to demonstrate the large negative expansion effects of such metamaterial. The results showed that the effective NHE ratio of the metamaterial is dependent of the curvature of the curved ligament and the size of both the ligament and the connecting rod. The ultra-large NHE ratios about −80% for the 2D structure and −90% for the 3D version can be obtained by adopting the structural parameters. The newly designed metamaterials have potential applications in medical and other fields.

MRE and STMP used in SIIB were prepared, of which the changes of shear storage modulus and damping factor with the magnetic field under different strain are analyzed. The mechanical properties of the SIIB under small displacement, medium displacement, and large displacement are tested, respectively, and the hysteretic characteristics of force–displacement are analyzed. The dynamic mechanical model combining the rheological model, phenomenological model, and bilinear restoring force model is established to represent the behavior of the SIIB.

Adsorption using solid sorbents is proving as an effective strategy for CO2 capture and reuse. The aim of this study was to develop amino-functionalized magnetic nanoparticles by depositing various amines through co-precipitation or impregnation-sonication. Structural characteristics were studied through SEM, BET and XRD analyses, evidencing coarse particles with low crystallinity and surface areas of 100–150 m2 g−1, while FT-IR confirmed CO2 interacting with substrate. The load of functional group, particles stability, and CO2 sorption capacity were assessed through elemental and thermogravimetric analysis. It was found that loads of functional groups ranging from 1.6 to 6.1 wt.%. were deposited, and most samples showed sound stability up to 100°C. Sorption capacities were in the range 0.2–1.5 g gNH2 −1, the highest being 1.46 g gNH2 −1 for ɛ-aminocaproic acid. Such sample also exhibited good recyclability, with a performance drop of 11% after many cycles. CO2 uptake decreased with increasing temperature in the range 25–45°C, suggesting a chemical bond between CO2 and amines. Amino functionalized particles could thus be an interesting solution for CO2 capture and utilization thanks to fast kinetics, recyclability, and ease of separation.
