Pictorial representation of the timeline for H-PDLC grating formation. The cases (a), (b), (c), and (d) show extreme morphologies possible based on the relative time scales for the events listed on the timeline. , , and are nucleation time, gelation time, and diffusion time to , respectively. is the grating period [76].
