Fully aliphatic polyimides (APIs) were prepared from rel-(1'R,3S,5'S)-spiro[furan-3(2H),6'-[3]oxabicyclo[3.2.1]octane]-2,2',4',5(4H)-tetrone (DAn) as dianhydride, and either cis-trans-1,4-diaminocyclohexane (mix-DACH) or trans-1,4-diaminocyclohexane (trans-DACH) as diamine. The solubility, optical transparency, and thermal properties of the polyimides were investigated. The solubility and decomposition temperature of the APIs were found to be correlated with their intermolecular regularity. Triblock copolyimides were synthesized through the incorporation of a thermally labile polymer, poly(propylene glycol) (PPG), into the APIs, and their thermal properties were studied. Nanoporous thin films of the full APIs were prepared via thermolysis of the labile block in the copolyimide films. Phase separation and nanopore formation in the copolymer films were confirmed via atomic-force microscopy (AFM) and scanning electron microscopy (SEM), respectively.
