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.本研究以路易斯安那湾虾（Litopenaeus setiferus）的虾壳废弃物为原料，经梯度温度热处理后，通过球磨工艺制备为虾壳粉末。分别采用马来酸酐、硬脂酸对虾壳粉末进行表面改性处理，并设置未改性对照组；通过溶液加工结合机械研磨的工艺，制备得到虾壳-聚乳酸（PLA）复合颗粒。以该复合颗粒为原料，通过挤出成型工艺制备复合丝材。本数据集包含原始虾壳的热性能数据，以及马来酸酐表面改性过程中形成共价键的相关表征结果；同时收录了复合颗粒的热性能数据，以及表面活性剂对挤出丝材形貌、密度及口模胀大性能的影响数据，以评估该复合体系作为工程加工材料的应用可行性。 该数据库共分为五个文件夹： 1. "丝材重量与直径"：内含多个Excel（.xlsx）格式文件，记录了每种表面改性处理下5根挤出丝材试样的重量与直径数据。 2. "傅里叶变换红外光谱（FTIR）"：内含1个Excel格式文件，包含经马来酸酐表面改性及未改性虾壳的FTIR谱图数据。 3. "光学显微成像"：文件夹内存储了放大倍数分别为10×、20×、40×的球磨虾壳粉末TIFF格式光学显微图像。 4. "实物照片"：内含所有表面改性处理对应的干燥虾壳、球磨虾壳及挤出丝材的TIFF格式数码照片。 5. "热重-差示扫描量热法（TGA-DSC）"：收录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。
