Fundamental analysis of molecular interactions between polyetheretherketone (PEEK) and meta-/para-polyetherimide (m-/p-PEI)

The main objective of this international research project is to answer fundamental chemistry questions on the molecular interactions between high-performance polymers of polyetheretherketone (PEEK) and polyetherimide (PEI). This research project is a subpart of my Ph.D. project that aims to develop new high-performance polymer blends for the aerospace sector, i.e. to replace aluminum in the manufacturing of the next-generation lunar rover.
Currently, most rovers sent to the Moon or Mars are constructed using aluminum and its alloys since they provide strong mechanical resistance, along with the capacity to resist the harsh spatial and lunar environments. However, for the chassis of a rover, aluminum presents limitations such as high density, high thermal conductivity, and limited on-site repairability. Hence, there is a strong interest in designing new materials that can improve and/or solve these issues. High-performance PEEK-based blends and nanocomposites are promising candidates since they can potentially combine lightness, low thermal conductivity, repairability, 3D printability, and remarkable thermal, chemical, and mechanical resistance. The new fundamental knowledge resulting from this internship will allow tailoring blends of PEEK and PEI at the molecular scale to obtain the best mechanical and thermal properties for the targeted application.
