Abstract
A method of modifying liquid crystal polymers, which involves a step of irradiating a liquid crystal polymer with the laser beam having a pulse width of 10−12 seconds or less. Using the invention method, the physical strength of the liquid crystal polymers can be improved as compared with the conventional liquid crystal polymers.
Claims18
A method of modifying liquid crystal polymers, which comprises a step of irradiating liquid crystal polymer with the laser beam having a pulse width of 10−12 seconds or less, wherein average output power of the laser beam is adjusted within the range so that abrasion does not occur in the focused portion of the irradiated object, and
- the modification effects comprise decreasing transmittance of terahertz (1012 Hertz) electromagnetic waves.
A method of modifying liquid crystal polymers, which comprises a step of irradiating a thermotropic liquid crystal polymer with the laser beam having a pulse width of 10−12 seconds or less, wherein average output power of the laser beam is adjusted within the range so that abrasion does not occur in the focused portion of the irradiated object, and the modification effects comprise decreasing transmittance of terahertz (1012 Hertz) electromagnetic waves.
A method of modifying liquid crystal polymers, which comprises a step of forming a solid film of a thermotropic liquid crystal polymer, and a step of irradiating the solid film with the laser beam having a pulse width of 10−12 seconds or less, wherein average output power of the laser beam is adjusted within the range so that abrasion does not occur in the focused portion of the irradiated object, and
- the modification effects comprise decreasing transmittance of terahertz (1012 Hertz) electromagnetic waves.
A method of modifying liquid crystal polymers, which comprises a step of forming a melt or a molten state of a thermotropic liquid crystal polymer, and a step of irradiating the melt or the molten state with the laser beam having a pulse width of 10−12 seconds or less.
