Extrusion of Shrimp Shell - Polylactic Acid Composites: Dataset for the Impact of Surfactants on Morphology and Thermal Properties

Shrimp shell waste obtained from Louisiana Gulf shrimp (Litopenaeus setiferus) was heat-treated at varying temperatures and ground into a powder by ball-milling. The powder was used with and without surface treatment with maleic anhydride or stearic acid to form shrimp shell - polylactic acid (PLA) composite granules by solution processing and mechanical grinding. These granules were used as feedstock for the extrusion of composite filaments. The dataset shows the thermal properties of the shrimp shells and the presence of covalent bonding for surface treatment with maleic anhydride. The thermal properties of the composite granules and the influence of the use of surfactants on the morphology, density, and die swell of the extruded filaments are also collected to assess their use as a manufacturing material. The database is organized into five folders. The folder "Filament Weight and Diameter" contains .xlsx files containing the weight and diameter of five specimens of the extruded filaments for each surface treatment. "FTIR" contains an .xlsx file with data for the FTIR spectra of shrimp shells with and without surface treatment with maleic anhydride. Optical images in .tiff format of the ball-milled shrimp powder at 10x, 20x, and 40x magnification are found in the folder "Optical Microscopy". "Photos" contains digital photos in .tiff format for the dried shrimp, ball-milled shrimp, and extruded filament for each surface treatment. Lastly, the folder "TGA-DSC" contains TGA and DSC data for the raw shrimp shells and the composite granules.本数据集以路易斯安那湾虾（Litopenaeus setiferus）的虾壳废弃物为原料，经不同温度梯度热处理后通过球磨工艺研磨为粉末。分别采用经马来酸酐（maleic anhydride）或硬脂酸（stearic acid）表面处理与未表面处理的该粉末，通过溶液加工结合机械研磨制备得到虾壳-聚乳酸（polylactic acid, PLA）复合颗粒。将上述复合颗粒作为原料，经挤出成型工艺制备复合丝材。 本数据集收录的内容包括：虾壳的热性能数据，以及马来酸酐表面处理过程中共价键形成的相关表征数据；复合颗粒的热性能数据，以及表面活性剂的添加对挤出丝材的形貌、密度与口模胀大（die swell）的影响数据，以此评估其作为工程制造材料的应用潜力。 该数据集共分为五个文件夹： “丝材重量与直径（Filament Weight and Diameter）”文件夹内含.xlsx格式文件，记录了每种表面处理方案下5根挤出丝材试样的重量与直径数据； “傅里叶变换红外光谱（FTIR）”文件夹内含1个.xlsx格式文件，存储了经马来酸酐表面处理与未处理虾壳的傅里叶变换红外光谱数据； “光学显微镜（Optical Microscopy）”文件夹存储了放大倍率分别为10×、20×、40×的球磨虾粉光学显微图像，图像格式为.tiff； “照片（Photos）”文件夹内含各表面处理方案下干燥虾壳、球磨虾粉及挤出丝材的数码照片，照片格式为.tiff； “热重-差示扫描量热法（TGA-DSC）”文件夹存储了原始虾壳及复合颗粒的热重分析（TGA）与差示扫描量热法（DSC）数据。
