This study investigates graphene-reinforced thermoplastic polymers specifically polyether ether ketone (PEEK), polyethylene terephthalate glycol (PETG), and polylactic acid (PLA) fabricated through additive manufacturing techniques. Traditional materials often suffer from limitations in structural integrity, flexibility, and thermal stability, presenting challenges for their application in energy storage. This research aims to evaluate the mechanical properties of these graphene-reinforced polymers to assess their suitability for energy storage components. Using additive manufacturing, test samples were fabricated, and mechanical testing was conducted to evaluate tensile, flexural, and compression strengths. The results indicate that graphene-reinforced PEEK (G-PEEK) exhibits superior mechanical performance, with an ultimate tensile strength of 120 MPa, Young’s modulus of 1700 MPa, ultimate flexural strength of 160 MPa, and ultimate compression strength of 200 MPa, making it an ideal candidate for applications requiring high structural integrity. Graphene-reinforced PETG (G-PETG) offers a balance of strength and flexibility, with an ultimate tensile strength of 55 MPa, while graphene-reinforced PLA (G-PLA) serves as a cost-effective option, despite lower mechanical properties (ultimate tensile strength of 45 MPa).</p>\u0000 </div>","PeriodicalId":7372,"journal":{"name":"Advances in Polymer Technology","volume":"2024 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/adv/6464049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142861326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Migration of Cosmetic Components Into Polyolefins","authors":"Laetitia Bolte,&nbsp;Heiner Gers-Barlag,&nbsp;Guido Heinsohn,&nbsp;Rolf Daniels","doi":"10.1155/adv/2680899","DOIUrl":"https://doi.org/10.1155/adv/2680899","url":null,"abstract":"<div>\u0000 <p>Polyolefins such as high-density polyethylene (HDPE), low-density polyethylene (LDPE), and polypropylene (PP) are among the most widely used packaging materials in the cosmetic industry. Since these materials are in direct contact with cosmetic products, various components of the products are adsorbed to the packaging material’s surface and migrate within the amorphous regions of the polyolefin. This migration process, which occurs in both virgin and post-consumer recyclate (PCR) materials, can lead to deformation of the packaging. In this study, different types of virgin and PCR pellets were examined to investigate their interaction with cosmetic products and to understand the factors influencing the migration process. The migration of cosmetic oils was observed in all pellet samples, depending on the composition of the product and environmental conditions. The process was characterized by the weight gain of the plastic pellets and further identified through nuclear magnetic resonance (NMR) and infrared (IR) spectroscopy. Additionally, differential scanning calorimetry (DSC) and gel permeation chromatography (GPC) measurements were performed to analyze the polymer structure. Components with lower molecular weight (MW), high nonpolarity, and elevated temperatures were found to accelerate the migration process. Moreover, migration occurred more slowly from oil-in-water emulsions with larger droplet sizes compared to water-in-oil systems with smaller droplets. Among the different polyolefins, PP demonstrated a higher uptake of migrating components but at a slower migration rate compared to HDPE and LDPE. When comparing virgin and recycled polyolefins, it was observed that migration was consistently slower in virgin materials than in recycled ones. The ability of oils to migrate is influenced by the molecular structure of the polymers: high density, crystallinity, and low levels of branching reduce both the migration speed (MS) and the maximum saturation, as seen in virgin HDPE. In contrast, materials like LDPE, with a less dense polymer structure, exhibited higher MSs and saturation limits. As a control, polyethylene terephthalate (PET) was used, and it showed no migration due to the polymer’s high density.</p>\u0000 </div>","PeriodicalId":7372,"journal":{"name":"Advances in Polymer Technology","volume":"2024 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/adv/2680899","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes the incorporation of the nystatin coated copper oxide (CuO) particles having desirable conductivity and antifungal properties, as a filler in the PMMA denture to address their low thermal conductivity, low impact strength, low fatigue resistance, and microbial adhesion. The prepared nystatin coated CuO particles were characterized with several analytical techniques. The nystatin coated CuO particles were mixed in different ratios (0%, 1%, 2%, and 4%) in PMMA corresponding to groups C, E1, E2, and E3, respectively. The prepared samples of composite PMMA with nystatin coated CuO were evaluated to determine their transverse strength, impact strength, Vickers hardness (HV), and thermal conductivity. Furthermore, antifungal properties of CuO particles, nystatin coated CuO particles, and their acrylic composites were evaluated against Candida albicans. Scanning electron microscopy (SEM) analysis confirmed the particles’ spherical and irregular shapes. The particle sizes range from nano to micron level. Fourier-transform infrared spectroscopy (FTIR) and energy dispersive X-ray spectroscopy (EDX) analysis confirmed the coating of nystatin on CuO. X-ray diffraction (XRD) analysis showed the diffraction patterns and planes of CuO monoclinic shape structure.
