摘要： A polymerizable liquid crystal composition containing two polymerizable liquid crystal compounds (A) and (B) is provided. A polymer of compound (A) exhibits a reverse wavelength dispersion property and the phase difference value [R(A,3000,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 3000 mJ/cm2 varies in a positive sense relative to the phase difference value [R(A,500,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 500 mJ/cm2. A polymer of compound (B) exhibits a reverse wavelength dispersion property and the phase difference value [R(B,3000,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 3000 mJ/cm2 varies in a negative sense relative to the phase difference value [R(B,500,450)] at a wavelength of 450 nm measured after irradiation in an oriented state with ultraviolet ray at 500 mJ/cm2.

摘要： A polymeric scaffold contains pendant liquid crystal side chains and has fully interconnected pores. Such a polymeric scaffold will preferably be 3D in nature and elastomeric, biocompatible and biodegradable. Such 3D liquid crystal elastomer (LCE) scaffolds can be used for various biomedical applications, including cell culture applications. A method for the production of such a polymeric scaffold containing liquid crystals and having interconnected pores is also disclosed that uses a metal foam sacrificial template as a scaffold to produce the polymeric smart response scaffold of the present invention. Consistent and controlled pore sizes result from etching the sacrificial metal foam template away from the polymeric scaffold, permitting the incorporation of growth factors, when needed, for enhancing cell viability and proliferation.
