A new gyroid family member, the tetragonal gyroid surface (shifted tG), was designed on the basis of a binary self-assembly system containing diblock copolymer PS--PAA as the main building block and the small surfactant cetrimonium bromide (CTAB) as the structure manipulator. Featuring shifted double-gyroidal networks, shifted tG belongs to a tetragonal symmetry with the low-symmetry space group 4/ and shows a widened photonic band gap along with shifting degrees, initiating a new gyroid symmetric system.

对称操纵的四方陀螺结构：陀螺表面家族的全新成员

陀螺仪家族的一个新成员，四方陀螺仪表面（转移tG），是在二元自组装系统的基础上设计的，该二元自组装系统包含二嵌段共聚物PS-PAA作为主要构件和小表面活性剂溴化十六烷基三甲基铵（CTAB）作为结构单元。结构操纵器。位移tG具有位移双螺旋网络，属于低对称性空间群4/的四方对称性，并且随着位移度数的增加，光子带隙变宽，开创了一种新的螺旋对称系统。
