Abstract
Description
これらの材料では、結晶又は液晶ドメインは、ランダムに配向されていると散乱を示す。結晶が溶融又は液晶相が等方性相へ遷移すると、散乱はなくなる。用いられ得る材料は、小分子、ポリマ、共重合体、架橋系である。液体又はポリマの混合物であるが、分散系でもある混合物を用いることも可能である。
そのような材料は、温度制御可能な散乱を示す。そのような系では、2つ又はそれ以上の成分が混合されている。ある温度において、全ての成分が混和可能であり、単一の相が得られる。高い臨界温度挙動を示す系の場合、ある温度よりも低いと、系は2つの相に分離し、散乱を示す。低い臨界温度挙動を示す系の場合、ある温度よりも高いと、系は2つの相に分離し、散乱を示す。目下の用途では、前者の系が適切である。そのような系は、ポリマの混合物、溶液及び塩を含む系を用いて生成される。
