In this study, we aimed to determine the possible antiviral effects of polyethylene glycol (PEG) coating on feline coronavirus (FCoV). The PEG coatings were synthesized by a simple mixing method with a water-based acrylic binder in different weight percentages (3, 5, 10, 15, 20, and 25 wt%). The Spearman–Karber technique was used to calculate the viral titers, which were then expressed as the tissue culture infectious dose at 50 % CPE (TCID50/ml). 20 wt% PEG could result in a 3 log10 reduction in virus titer with an inhibition rate of approximately 99.9 % against FCoV. The increment of PEG weight percent from 0 to 25 wt% decreases the hardness and glass transition temperature of the coatings from 38.1 to 5.5 HV and 15.45 to −15.48 °C. Apart from that, the wettability analysis has revealed that PEG coating is hydrophilic with water contact angle (WCA) of around 75 ± 0.5°–85 ± 0.5°. Adding 25 wt% of PEG makes the coating to be superhydrophilic with WCA of 39.85 ± 0.5°.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140129674","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}

Two types of organically modified nanoclay, Cloisite 93A (C93A), and Cloisite 30B (C30B), were incorporated at various weight percentages into the PHB matrix to create the nanocomposites. Comparative analyses were conducted between PHB/C93A and PHB/C30B to assess their tensile and impact properties in relation to the matrix polymer. Between the nanocomposites, the PHB/C93A nanocomposites shows an optimum tensile modulus of 949 Mpa with a 3 wt% clay loading, while PHB/C30B nanocomposites demonstrated improved percentage elongation at break of 5.33 % and enhanced Izod impact strength of 39.67 J/m at 3 wt% of clay load. The thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC) signifies the thermal behavior of both the matrix and nanocomposite. The degree of crystallinity is observed to be 47 % in case of the PHB/C30B nanocomposites as compared to the PHB/C93A nanocomposites as 38 %. Again in case of thermogravimetric analysis (TGA), the maximum % char of 5.198 is observed for the PHB/C30B nanocomposites. The enhanced viscoelastic behavior of the PHB/C93A nanocomposites was attributed at a peak of approx. 55–60 °C due to the incorporation of C93A nanoclay into the matrix in the study of dynamic mechanical analysis (DMA). The morphological investigation using WAXD analysis showcased particle clay intercalation and dispersion within the PHB matrix, indicating effective clay-matrix interactions. Overall, this study sheds light on the enhanced properties of PHB nanocomposites with the incorporation of organoclay, offering potential applications in various industries.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140071738","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}

Fuel cells, particularly microbial fuel cells (MFCs), offer a promising avenue for sustainable energy production. Proton exchange membranes (PEMs) are critical components in MFCs, but the high cost of Nafion, the gold standard PEM, poses a significant challenge. In this pioneering study, we tried to fabricate PEMs by crafting them from polymethyl methacrylate (PMMA), coupled with innovative combinations of potassium thiocyanate (KSCN) and citric acid. The synthesized membranes were studied for their water uptake capacity, ion exchange capacity and potential applications in MFC. The maximum remarkable water uptake capacities of up to 70 % for 10 % KSCN and 64 % for 7.5 % citric acid compositions was observed. Furthermore, these PEMs exhibit ion exchange capacities (IEC) ranging from 0.024 to an impressive 0.69 meq/gm, with the 7.5 % citric acid variant showcasing the highest IEC (0.69 meq/gm). The membranes having better IEC were applied to microbial fuel cell. This results in maximum power density of 50.03 μw/cm2, underscoring the tremendous potential these membranes hold as a cost-effective and environmentally friendly alternative to conventional PEMs in MFCs.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140076212","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 PUI possessed good film-forming property, a high glass transition temperature (T g = 193 °C) and good thermal stability (5 % weight loss temperature T d up to 320 °C). Y-Structured inverted ridge polymer optical waveguides were designed and fabricated using the PUI as the waveguide core material.

In this study, hydroxyapatite-chitosan-alginate-polyamide (HCAP) synthetic scaffold was fabricated using the thermally induced phase separation (TIPS) technique. The scaffold was cross-linked with either a chemical cross-linker (calcium chloride, 2-hydroxyethyl methacrylate (HEMA), or glutaraldehyde (GTA)) or a physical cross-linker (gamma irradiation (IR)) resulting in scaffolds HCAP-CaCl2, HCAP-HEMA, HCAP-GTA, and HCAP-IR, respectively. The cross-linked scaffolds were characterized based on physicochemical properties, cytotoxicity, and biocompatibility. HCAP-GTA showed the highest density and the lowest swelling ratio and biodegradation rate closely matching with those of the HCAP-IR. Porosity and density of the HCAP, HCAP-IR, and HCAP-GTA scaffolds were 92.14, 87.26, and 83.33 %, and 0.241, 0.307, and 0.335 g/cm3, respectively. The swelling ratio for the same scaffolds was 149, 110, and 108 % after 72 h of observation. Brine shrimp cytotoxicity and RBC biocompatibility assay confirmed the non-toxic nature of HCAP-IR and HCAP-GTA scaffolds. The HCAP-IR scaffold was tested for bone regeneration in the rabbit mandible defect model. Histological analysis revealed the regeneration of new bone and restoration of bone defect at the site of injury. These findings indicate that radiation induced physically cross-linked HCAP scaffold could be used as an alternative in bone defect replacement therapy.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139756078","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}

In dynamic rheology, the same sample demonstrated maximum values of G′ and G″ at a constant frequency of 30 rad/s, G′ and G″ improved by 25 and 11 times, respectively, over unmodified STF. Furthermore, for constant strain amplitudes, the maximum values of G′ and G″ were observed at a strain amplitude of 700 %. G′ and G″ improved by approximately 6.5 and 6 times over unmodified STF, respectively.
