1. 毕业设计（论文）的内容和要求
本课题主要是通过利用微流控技术制备聚合物螺旋微纤维，再对纤维进行碳化处理得到碳基螺旋纤维太阳能吸收材料，然后进行光热转换效率和水蒸发速率的测试。
运用扫描电镜（SEM）、透射电镜（TEM）等对材料进行表征，观察材料的结构和形貌，使用红外（IT-IR）和XPS 等表征材料的化学组成和元素种类。
通过本课题的研究，使学生了解微流控制备螺旋纤维和界面太阳能光热水蒸发的相关知识，了解国内外研究现状，并对材料化学工程、仪器分析有更进一步的认识；培养学生独立查找和阅读国内外文献的能力；了解各种表征手段、实验室安全规程、各级药品的储存与保管，锻炼本科生独立思考和独立实验的能力。
