aLow viscosity of the liquid crystals leads to the fast response time in the displays.Since a large △ε value has an inclination to cause higher viscosity, liquid crystals have to be designed in a manner so that viscosity and large △ε are well balanced each other. 低黏度液晶在显示导致...
A new empirical relation between liquid dynamic viscosity, temperature, and chemical constitution of organic compounds is proposed. The method is based on the De Guzman-Andrade equation and the introduction of a new property, the equivalent chain length of a compound, defined as the chain length ...
