In addition, a pen-tip-shaped microneedle array (MN-C) was developed on the basis of the characteristics of the aforementioned two types of arrays. The results indicated that HEMA hydrogel, when photopolymerized under a fixed ultraviolet A (365 nm) intensity of 25 mW/cm² for 15 min, achieved optimal polymerization, with its elongation, moisture content, oxygen permeability, and maximum load-bearing capacity being 80%, 55.1%, 22.8 barrer, and 96.5 gf/cm<sup>2</sup>, respectively. In addition, when the three microneedle arrays were fabricated from HEMA hydrogel under the aforementioned optimal process parameters, they exhibited penetration diameters of less than 500 μm and penetration depths of 300–600 μm in pig ear piercing experiments. Among the three microneedle arrays, the MN-A array exhibited the highest drug load and effective penetration depth, whereas the MN-B array exhibited the smallest wound area, thereby effectively reducing tingling sensation. The MN-C array, which was an improvement over the MN-A and MN-B arrays, not only exhibited the highest penetration stress (3.9 mN) but also retained the high drug load and low tingling sensation characteristics of the other two arrays.

The first stage relates to the organic treatment of the montmorillonite (MMT) using an alkylammonium (hexadecylamine C<sub>16</sub>H<sub>35</sub>N) in order to increase the interfoliate distance, resulting in an organically compatible modified montmorillonite (OMMT). The second one is reserved to the optimization of the polyurethane (PU) formulation. Composite’s foams (PU/ OMMT) are formulated via the free expansion process. Moreover, the physicochemical characterization of the developed foams was carried out. Characterization of the obtained foams have been done by various methods such as: FTIR, DSC, TGA, XRD, SEM, Charpy test, and normalized flammability test (UL 94 HB). FTIR analysis confirms the PU formation and the incorporation of the organically treated montmorillonite (OMMT) into the polyurethane (PU) via the in-situ polymerization. Add to that, it is assigned by the XRD analysis that the interfoliate distance has been increased from 11.63°A to 27.96°A using the hexadecylamine and the PU/ OMMT composite foams present a mixture of intercalated and exfoliated structure. The SEM images prove that the addition of 5 wt % of OMMT has resulted in similar cell size compared to the pristine PU formulation (about 100 µm). DSC and TGA analysis proved the good thermal stability of PU foams and confirmed that the PU/ OMMT composite foam is the most stable one.

However, the poor mechanical properties and incomplete gel-breaking severely limit the practical application of this strategy. Herein, a temperature and pH-responsive hydrogel P(ACG-co-AM)-MMT was prepared by copolymerizing a natural amino acid derivative monomer N-acryloyl glycine (ACG) and acrylamide (AM) with montmorillonite (MMT) as filling material. Hydrogen bonding is the main driving force in hydrogel formation, as confirmed by infrared spectroscopy. The introduction of MMT plays a key role in enhancing the mechanical properties of hydrogels. This successfully overcame the issues of inadequate mechanical properties-rapid degradation trade-off in hydrogel temporary plugging materials. The results show that the hydrogel can withstand the pipeline pressure up to 84 kPa and effectively plug the pipeline. Due to the reversibility of hydrogen bonds, the hydrogel can realize the transformation of sol-gel-sol under temperature stimulation. The plugged area of the pipeline is removed by injecting thermal-produced water. When the hot water temperature is 85 ℃, the pipeline changes to the dredging state only 21 min, dramatically simplifying the operation time. P(ACG-co-AM)-MMT hydrogel has great potential as a temporary plugging material in replacing partially damaged oil pipeline plugging operations.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":658,"journal":{"name":"Journal of Polymer Research","volume":"31 11","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142636980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PLA’s environmentally friendly nature makes it an attractive candidate for sustainable and recyclable shape memory applications. However, PLA’s slow shape recovery rate and low shape fixation percentage hinder its applicability as shape memory material. In the present study, we report MXene-modified PLA (PLA/Mx) nanocomposite with enhanced shape memory effect. Solution processing methods mediated the loading of the MXene in the PLA matrix. Different samples were prepared by varying the weight% of the MXene in the PLA matrix. The structure and morphology of samples were analyzed by XRD and TEM characterization. Thermogravimetric analysis was performed to measure the thermal stability of the composite. Compared with pure PLA, with MXene loading, the PLA/Mx composites show an increase in thermal. The shape recovery study on PLA/Mx samples used temperature as an external stimulus. The PLA/Mx composite exhibited a significantly improved shape memory effect than the PLA alone. The study exhibits that a shape memory effect can be improved by tuning the MXene additive loading in the PLA matrix. The material shape recovery effect was validated by fabricating the spiral structure. The fast shape recovery time 3s and shape fixation/recovery of > 95% was observed for 1 wt% of PLA/Mx.
