Molecular Design
Because many factors, including MW (which has been described in the previous
section), backbone flexibility, tail length, architecture, and so on, strongly affect the
phase behaviors of MJLCPs (Chen et al. 2010), it is necessary to understand the
relationships between the chemical structure and the phase behavior. Then, a rational
