  The Structural Effects on the Pretilt Angle of Alignment Materials with Alkylcyclohexylbenzene as a Side Chain in Polyimides

  摘要：

  We have investigated the relationship between the surface property of rubbed polyimides and the variation of pretilt angle according to the side chain and main chain structures. We calculated the surface free energy of synthesized polyimide surface by measuring the contact angles of distilled water and methylene iodide on the rubbed polyimide surface. Consequently, we found that pretilt angles on rubbed polyimides changed according to the side chain and main chain structures of the polyimide. Our calculations show that LC pretilt angles of polyimide films with a liquid crystal structure as a side chain were approximately 90 degrees when a linear and rigid polyintide main chain and a side chain of suitable length were employed.
