Movies

Movie #1

1. 

   By applying electeric voltage(900V) across the MBBA liquid crystal film, some vortices are produced.

   Frame dimensions: 1mm*8mm
   

Movie #2

1. 

   The vortices pattern change with increasing and decreasing external electric field. This movie shows the vortices are controllable with external electric field in MBBA.

   Frame dimensions: 3mm*8mm
   

Movie #3

1. 

   Evolution of liquid crystal(MBBA) film director (between two perpendicular polarizers).

   Frame dimensions: Circular frame with radius of 3.5mm
   

Movie #4

1. 

   Suspended MBBA film has been subjected between two perpendicular polarizers, and electric voltage and field are applied on the film.

   Frame dimensions: Circular frame with radius of 3.5mm
