Reflection characteristics of cholesteric liquid crystal microcapsules with different geometries

New Approach toward Reflective Films and Fibers Using Cholesteric Liquid-Crystal Coatings

“…Therefore, the angle between the incoming light and the helix (denoted as θ) is expected to increase from the middle of the fiber toward the edges (Figure b), which causes the blue shift at the edges. Similar observations were reported for CLC microcapsules …”

“…Similar observations were reported for CLC microcapsules. 21 Finally the effect of the viewing position on the perceived color was investigated. Photographs were taken at different angles varying respectively in the plane perpendicular (α) and the plane parallel (β) to the fiber axis (Figure 8a).…”

Development in liquid crystal microcapsules: fabrication, optimization and applications

“…where CLC is the weight percentage of the LC core, and ρLC and ρshell are the density of the LC core and the polymer shell, respectively. [95] It is worth mentioning that the LC cores and LC-Ms are simplified into a normal sphere in the above two equations. The threshold electric field (Eth), which is used to measure the responsive sensitivity, depends heavily on the anchoring elastic forces between the LC molecules, and thus is related to the core size.…”

Particle Size Controlled Chiral Structural Color of Monodisperse Cholesteric Liquid Crystals Particles

“…[7][8][9] Spherical CLCs particles are favored by researchers due to their angle-independent structural coloration. [10][11][12][13][14][15] Ongoing research focuses on developing CLCs particles with the angle-independent properties by employing microfluidic, [16][17][18][19][20][21][22] emulsion polymerization, [23,24] and other techniques. [13,25,26] CLCs particles are widely used in the field of sensors because they can directly output optical signals without the need for output systems.…”
