Abstract

This work focuses on the development and characterization of nanocomposite coatings designed for long-term space missions, aiming to prevent bacterial adhesion while maintaining optimal physical and chemical properties. Preventing biofilm formation and bacteria proliferation on surfaces is a crucial aspect in space, since they pose serious risks to astronaut health, spacecraft durability, and mission success. Therefore, spacecraft materials must withstand space conditions while resisting bacterial colonization. The nanocomposite coatings were fabricated using a fluorinated polyimide (PI) matrix filled with different concentrations of graphene nanoplatelets (ranging from 1 to 30 wt%). The PI matrix was synthesized from aromatic diamine and dianhydride in a bio-based and non-toxic solvent, dimethyl isosorbide (DMI), following a green protocol. Several experimental techniques were used to investigate the physicochemical and morphological properties of the PI/GNP nanocomposite coatings, assessing their potential application in space environments for antibacterial purposes.

用于空间应用的聚酰亚胺/石墨烯纳米复合材料：人类探索任务的潜在抗菌涂层

这项工作的重点是为长期太空任务设计的纳米复合涂层的开发和表征，旨在防止细菌粘附，同时保持最佳的物理和化学性能。防止表面生物膜的形成和细菌的繁殖是太空中的一个关键方面，因为它们对宇航员的健康、航天器的耐久性和任务的成功构成严重风险。因此，航天器材料必须承受空间条件，同时抵抗细菌定植。纳米复合涂层采用氟化聚酰亚胺（PI）基质，填充不同浓度的石墨烯纳米片（重量百分比从1%到30%不等）。以芳香二胺和二酐为原料，在生物基无毒溶剂二甲基异山梨酯（DMI）中，按照绿色方案合成了PI基质。采用多种实验技术研究了PI/GNP纳米复合涂层的物理化学和形态特性，评估了其在空间环境中抗菌用途的潜在应用。
