Similarly, micro/nano‐indentation has gained popularity as a technique for assessing the surface mechanical characteristics of polymers. The present study conducted comprehensive experiments using cyclic micro‐indentation on engineering polymers, specifically poly‐ether‐ether‐ketone (PEEK), poly(methyl methacrylate) (PMMA), and poly(tetra‐fluoroethylene) (PTFE). An appropriate and optimal indentation method has been proposed after analyzing the behavior and significance of all the input parameters in evaluating the properties. Both constant load multi‐cycle (CLMC) and progressive load multi‐cycle (PLMC) were considered for this investigation. A comparative evaluation has been conducted to assess two multi‐cycle tests on these materials. From the analysis of the input parameters, including maximum loads, loading and unloading rates, and the number of cycles, the unloading rate and indentation cycle are crucial factors in determining hardness (<jats:italic>H</jats:italic>) and elastic modulus (<jats:italic>E</jats:italic>). Increasing the loading rates leads to an increase in <jats:italic>H</jats:italic> and a reduction in <jats:italic>E</jats:italic> for all three materials. This effect arises from the thermal effect, which is characterized by the creep modulus and a closed hysteresis loop. Employing the holding duration and multiple cycle data in constant load multi‐cycle can significantly influence the creep behavior and use of the hysteresis loop for fatigue behavior. Similarly, a progressive load multi‐cycle indentation with a force greater than 0.5 N and a minimum of five cycles is the most accurate approach for evaluating surface mechanical parameters.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"14 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208238","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a wideband, low‐profile, and flexible antenna with excellent on body radiation performance for wearable applications. The antenna is designed using a low‐loss composite film based on PMMA‐PVDF‐HFP‐PZT and silver‐based ink. The proposed flexible antenna exhibits a wide bandwidth of 132.16% with a voltage standing wave ratio (VSWR) of less than two. It achieves a peak gain of 2.76 dBi at 2.92 GHz and maintains a maximum radiation efficiency of 80% across the 1.26–6.17 GHz frequency range. These characteristics demonstrate that the antenna is an effective solution for achieving high data rates and reliable communication links. The antenna's suitability for wearable applications is assessed by testing it on a simulated human body and analyzing its behavior under physical deformation. The results under bending showed only a minimal frequency detuning, which is negligible given the antenna's wide operational bandwidth. The specific absorption rate (SAR) analysis shows values of approximately 1.88 W/kg at 3.5 GHz with an input power of 0.5 W, and 0.279 W/kg at 5.8 GHz with an input power of 0.45 W, which complies with established safety limits for exposure. Overall, these results suggest that the proposed antenna is a viable solution for integration into wearable medical devices, such as a doctor's chest badge, enabling noncontact interactions and reducing the risk of bacterial contamination.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"15 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The goal of this research is to present a new method for extracting bicalutamide (BCT) from biological samples using a responsive polymeric nanoadsorbent that reacts to temperature and near‐infrared radiation (NIR). To achieve this, the surface layers of tungsten disulfide nanosheets are modified using poly (N‐vinylcaprolactam) and three generations of polymeric dendrimers. The adsorbent product is then characterized using thermogravimetric analysis, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, and X‐ray diffraction techniques. The drug loading operation on the proposed adsorbent is studied through central composite design and response surface strategy, with optimization for temperature (25–45°C), pH (5–9), and contact time (2–18 min). Nonlinear kinetic and adsorption isotherm analysis results show the best fit with Langmuir and pseudo‐second‐order models. The drug release process from the BCT‐loaded adsorbent is investigated via an HPLC‐UV system under both NIR‐irradiated and non‐irradiated conditions.

As structuring the bigel phases using convenient materials can enhance the main characteristics, this study aimed to develop bigel system based on a hybrid hydrogel consisting of gelatin and carboxymethylcellulose (CMC). The impact of incorporating various concentrations of CMC (0, 0.5, 1, 2, and 3% w/w) into gelatin‐based hydrogel at a constant organogel/hydrogel ratio of 60:40 was investigated on bigel properties. The integration of gelatin and CMC significantly affected the solvent holding capacity (SHC), microstructure, rheology, thermal, and textural properties. The results showed that bigel samples containing gelatin‐CMC had lower SHC compared to gelatin‐based samples. The integration of CMC to bigel formulation resulted in a significant decrease in hardness, cohesiveness, and adhesiveness also smooth texture. Differential scanning calorimeter (DSC) analysis of the bigels showed a descending trend in melting point from 99.07 to 98.60°C for bigel samples as the CMC concentration increased from 0% to 2%. This was followed by an increase in melting temperature (100.95°C) in the bigel containing 3% CMC. Particle size distribution data indicated that the droplet sizes of the bigels increased with the incorporation of CMC into the hydrogel phase, without displaying a distinct concentration‐dependent trend. The rheological characteristics of strain sweep, frequency sweep, and loss factor affected by gelatin/CMC concentration. Overall obtained results highlight that CMC incorporation to gelatin plays a crucial role in bigel offering different textural, rheological and thermal properties. So that carefully selection and optimization of gelatin and CMC concentrations in hydrogel phase are essential for tailoring the mechanical strength and stability of bigels for various applications such as drug delivery, cosmetic, and food industries. Regarding the desired properties of CMC, it could be recommend to use by combination with gelatin to create a structure–function aimed bigels.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"13 1","pages":""},"PeriodicalIF":3.4,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142208243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional pressure‐sensitive adhesives can enhance recoverability through cross‐linking but often demonstrate inadequate adhesive strength. In this study, three long‐chain crosslinking agents (CL) were synthesized using hydroxyethyl acrylate (HEA), dicyclohexylmethane diisocyanate (HMDI), polypropylene glycol (PPG), polyether amine (PEA), and hydroxyl‐terminated polybutadiene (R45V). The long‐chain CL agent contains numerous flexible segments that improve the recovery capability of the OCA while maintaining a certain level of adhesion. The optical clear pressure‐sensitive adhesive, crosslinked by three flexible crosslinkers, exhibits a low glass transition temperature (−60 to −40°C) and a low storage modulus (&lt;0.1 MPa), along with an appropriate 180° stripping force (6–8 N/25 mm).

The CSPs consist of poly (butyl acrylate) (PBA) as core and methyl methacrylate (MMA) copolymerized with glycidyl methacrylate (GMA) as shell. The effects of adding various amounts of the emulsion latex on the mechanical properties, thermal stability, adhesion, and microstructure of the cured epoxy resin were investigated. The CSPs were analyzed by transmission electron microscopy (TEM), Fourier‐transform infrared spectroscopy (FTIR), and differential scanning calorimetry (DSC). The mechanical properties, thermal stability, adhesion to aluminum plates, and microstructure of the cured epoxy resin were investigated by stress–strain, thermal gravimetric analysis (TGA), single lap shear test, and field emission scanning electron microscopy (FESEM), respectively. The addition of 7 wt.% emulsion latex to epoxy enhanced the tensile strength and the toughness of the dumbbell‐shaped samples by 421% and 4388% with respect to neat epoxy, respectively. Furthermore, the single lap shear strength increased in 33% and an increase of 71°C in the initial decomposition temperature of the epoxy was obtained by adding 7 wt.% CSP, without affecting the maximum decomposition temperature.
