From: Electric-field-aligned liquid crystal polymer for doubling anisotropic thermal conductivity
a diagram of crystal monomer under electric field. b The TEM of PBPE-C3-AA where the hard segment was marked. c Polarising RAMAN spectrum of liquid crystal polymers which were synthesised with and without electronic field (the dots are measured results and curves are fitted, blue ones represent PBPE-C3-AA-2kV while red ones represent PBPE-C3-AA). d X-ray reflection schematic of liquid crystal polymers with disordered crystal region. e X-ray reflection schematic of liquid crystal polymers with oriented crystal region. f, g WAXS spectra of PBPE-C3-AA and PBPE-C3-AA-2kV. h, i SAXS spectra of PBPE-C3-AA and PBPE-C3-AA-2kV. j A schematic of crystal zone and the molecular in them. k XRD spectrum of samples. (blue curve represents PBPE-C3-AA-2kV and the red one represents PBPE-C3-AA). l Relationship of IR absorption and the direction of dipole moment. m FTIR calculated from DFT calculation. n The measured FTIR of samples in the fingerprint region (blue curve represents PBPE-C3-AA-2kV and the red one represents PBPE-C3-AA). o The area ratio of the specific peaks between PBPE-C3-AA and PBPE-C3-AA-2kV.
