However, the precise positioning of pore formation is often challenging due to the uncontrolled temperature gradient within the materials during the TIPS process. Drawing inspiration from the coexistence of tubular pores with varying diameters in natural structures, a novel approach was devised to replicate this natural structure using a combination of biodegradable polymer (poly-L-lactic acid), a patterned cap-equipped mold, and a temperature-controllable one-directional-cooling apparatus. The pattern consisted of high-thermal-conductivity Ti alloy pins encased in low-thermal-conductivity polyethylene (PE). The differential thermal gradient between the pins and the PE portion of the cap facilitated the formation of tubular or flat-plate pores in the desired areas. Significantly, a porous structure featuring well-aligned flat-plate pores and a sandwich panel skeleton was successfully fabricated using a cosolvent system (benzene/dimethyl carbonate). It is anticipated that the innovative strategy incorporating the patterned cap, the one-directional-cooling apparatus, and the cosolvent system will introduce a novel and promising method for fabricating intricate porous structures extending beyond conventional polymer membranes and scaffolds.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 1","pages":"51 - 62"},"PeriodicalIF":4.7,"publicationDate":"2024-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142941240","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To do this, after grafting on the WO₃ nanoparticle surface with a thermo-sensitive poly [(vinyl methyl ether)]–<i>co</i>-[allylamine]s, three generations of PAMAM dendrimer using ethylenediamine and methyl methacrylate, were successfully grown formed. Nanostructures were characterized by using X-ray diffraction, FT-IR, SEM, TEM, GPC and TGA. Different parameters including temperature, pH, and contact times were considered to optimize the operating conditions and evaluate the potential of dendrimer nanocarrier for drug delivery. By analyzing the in vitro drug release after 6 h in fluids with different pH (5.6 and 7.4) and temperatures (37 and 50 °C), a good response was found at pH 5.6 and temperature 50 °C, which indicated controlled release of drug and the dual response (pH and thermo responsiveness) of the nanocarrier. Investigation of the effect of NIR irradiation showed that the release of DTX under NIR irradiation within 12 min was 99%, which was 10 times that without NIR. Photothermal effect of NIR induced the shrinkage of thermo-sensitive polymer which results in the control of drug. Besides, the adsorption kinetic was examined using Temkin, Dubinin, Freundlich, and Langmuir isotherm models. The sorption process of DTX by nanocarrier was best expressed by the Langmuir model with high coefficient of determination (R²) equal to 0.9985. Also, pseudo-second-order kinetic model confirmed the best correlation between experimental data with R² = 0.999. The results revealed that the pH/ thermo-sensitive nanocarrier is a promising candidate for drug delivery.</p></div>","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"33 1","pages":"12 - 28"},"PeriodicalIF":4.7,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, electrospun nanofibrous membranes (NFMs) are widely used in nerve tissue engineering due to their advanced properties such as low-cost, being uncomplicated, the potential to give direction to neurite outgrowth, and their highly manageable properties. Recently, the fabrication of functionalized NFMs has been proposed as a viable strategy to help restore the function of the nervous system. This would be accomplished by creating the ideal microenvironment that could mimic the features of the extracellular matrix of neural cells such as conductivity. The main objective of this project was to construct a biocompatible and electro-conductive NFM with the potential to promote proliferation and induce differentiation into neuron-like cells in PC12 cells. Basic PCL and gelatin based scaffolds seem to lack the highly desired properties of cellular implants for neural tissue engineering such as high biocompatibility, tailored biodegradability, high antibacterial, and ROS scavenging properties. For this purpose, Poly(ε-caprolactone)/gelatin (PG) electrospun nanofibrous scaffolds were coated with GO and GQD through Mussel-inspired polydopamine (DOPA) (PG-DOPA-GO and PG-DOPA-GQD). There is a dearth of research on the application of GQD in neural tissue engineering, and there is no comparative assessment of GO and GQD’s effectiveness when coated through DOPA on the surface of PG NFM, in PC12 differentiation. For the first time, the outcomes of these NFMs, as neural tissue engineering scaffolds are assessed and contrasted from the standpoints of surface, structure, mechanical, and biological aspects. Apart from that, as far as we know, this is the first work using graphene-based nanomaterials via polydopamine mediated coatings in PG NFMs for nerve tissue engineering. The NFMs structural analysis through SEM, FTIR, and EDAX determined that the nanofibrous membranes are porous and truly coated by DOPA, GO, and GQD. It was also demonstrated that PG-DOPA-GO and PG-DOPA-GQD NFMs are highly conductive, hemo-compatible, antibacterial, possessing good hydrophilicity. At the same time, they are displayed to be biodegradable with adjustable structural integrity and stiffness. The NFMs potential to induce the expression of neuron-like differentiation factors in the PC12 cells cultured on the scaffold was determined by introducing neurofilament-200 (NF200) and Nestin antibodies after 7 days’ cell ceding. Simultaneously, qRT-PCR analysis confirmed that the NF-200 and Nestin genes, both among the important genes regulating neural differentiation, are highly expressed when the conductivity and biocompatibility of the scaffold are increased through GO coating. Overall, the PG-DOPA-GO NFM was determined to outperform the other scaffolds regarding increased proliferation, viability, and neuron-like differentiation-related facto","PeriodicalId":659,"journal":{"name":"Journal of Polymers and the Environment","volume":"32 12","pages":"6698 - 6724"},"PeriodicalIF":4.7,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142664444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
