Abstract

3D printing has found applications across various sectors, including water treatment, where the incorporation of novel materials enhances sustainability and imparts specific functional properties. This study focused on the production of polymeric filaments for Fused Deposition Modeling (FDM) 3D printing, utilizing a PLA/PBAT blend infused with activated carbon and magnesium oxide, with concentrations up to 6 parts per hundred resin (PHR), for use in water treatment membranes. The distribution, composition, and morphology of the particles were assessed using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). Alterations in physical properties, including water absorption and contact angle, were observed in comparison to the pure commercial blend. An adsorption efficiency exceeding 60% for methylene blue was achieved, as confirmed by SEM analysis of the membranes. Furthermore, the filaments demonstrated suitability for the production of high-quality water treatment membranes, as evidenced by SEM and Optical Microscopy (OM) analysis.

用增材制造吸附亚甲基蓝的可生物降解聚合物膜

3D打印已经在各个领域得到了应用，包括水处理，在这些领域，新材料的结合增强了可持续性，并赋予了特定的功能特性。这项研究的重点是生产用于熔融沉积建模（FDM） 3D打印的聚合物长丝，利用PLA/PBAT混合物注入活性炭和氧化镁，浓度高达百分之六的树脂（PHR），用于水处理膜。利用扫描电子显微镜（SEM）和能量色散光谱（EDS）对颗粒的分布、组成和形态进行了评估。与纯商业共混物相比，观察到物理性质的变化，包括吸水率和接触角。通过扫描电镜分析，证实了膜对亚甲基蓝的吸附效率超过60%。此外，通过扫描电镜（SEM）和光学显微镜（OM）分析，证明了这些细丝适合生产高质量的水处理膜。

期刊介绍： The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
