PMID-20144477 In vitro evaluation of the long-term stability of polyimide as a material for neural implants

  • PI degrades at 85C in PBS; otherwise, it's stable.
  • mechanical tests only; no electrical tests.
  • Durimide 7510 contains a photo-initiator and an adhesion promoter. Spin-coatable.
    • Adhesion can be inhibited with C4F8
    • notably softer.
  • Dupont Kapton is PMDA-ODA (phenol linkage in the amide); PI-2611 is BPDA-PPD (aromatic carbon-carbon in the dicarboxcylic acid). The latter resists water uptake better.
