This invention concerns a polymer coating composition for use as non-focal optical power limiting dye containing polymeric materials. This composition contains: (1) one or more Modified Polymers comprising a Polymer, such as a hyperbranched polymer family, especially HB—PCS, HB—PU, HB—PUSOX or PC with one or more of: a) reverse saturable dye (RSA), b) multi-photon absorption dye (MPA), c) an azo dye, or d) absorption dye, which dye is chemically bonded to the pendant groups of the Polymer (along its chain and/or termini) or which forms a part of the backbone of the Polymer; (2) carbon nanotubes (CNT) as optical power limiters (OPL); and (3) a self-focusing component.
This Modified Polymer composition contains the dye incorporated into the polymer chain backbone or chemically bonded to the terminal groups at the ends or along the chain of the polymer, which provides efficient protection from laser beam damage along with its self-focusing mechanism.
本发明涉及一种用作非聚焦光功率限制染料含聚合物材料的聚合物涂层组合物。该组合物包含:(1)一种或多种改性聚合物,包括聚合物,如超支化聚合物家族,特别是HB-PCS,HB-PU,HB-PUSOX或PC,其中至少含有以下之一:a)反饱和染料(RSA),b)多光子吸收染料(MPA),c)偶氮染料或d)吸收染料,该染料化学键结到聚合物的吊挂基团(沿其链和/或末端)或形成聚合物的骨架的一部分;(2) 碳纳米管(CNT)作为光功率限制器(OPL);以及(3)自聚焦组分。该改性聚合物组合物含有染料并入聚合物链骨干或化学键结到聚合物的末端基团或沿聚合物链的某些部位,这提供了有效的保护,防止激光束损坏,并具有自聚焦机制。
