Two kinds of hydroxypropyl cellulose (HPC) films were prepared: one retained cholesteric liquid crystalline order (HPC-A), and another was amorphous (HPC-B). Gas transport phenomena in the HPC-A films were determined at 20ยฐC, which is below the T g of HPC, compared with those in the HPC-B films, by
Hydroxypropyl cellulose solid films crosslinked with two kinds of dialdehyde (glyoxal and glutaraldehyde), retaining cholesteric liquid crystalline order, were prepared by casting the liquid crystalline solution in methanol.

Temperature dependence of the swelling behavior in both water and propanol was determined for the crosslinked hydroxypropyl cellulose (HPC) films retaining cholesteric liquid crystalline order (CLCO) and for the crosslinked amorphous HPC films. The dependence of swelling behavior in water for the fi
