Structure and energetics of grain boundaries in self-assembled double-gyroid block copolymer networks
Jing Chen, Aiping Zhu, Dan Wei +2
Grain boundaries (GBs) are ubiquitous defects in crystalline materials. However, they remain less explored in block copolymer ordered phases. Here, we develop a self-consistent fie…
Phason-Driven Diversity of Nucleation Pathways in Icosahedral Quasicrystals
Gang Cui, Lei Zhang, Pingwen Zhang +2
The nucleation of quasicrystals remains a fundamental puzzle, primarily due to the absence of a periodic translational template. Here, we demonstrate that phasons - hidden degrees…
Phase Behaviour of X-Shaped Liquid Crystalline Molecules
Dan Wei, Zhijuan He, Yunqing Huang +2
X-shaped liquid crystalline molecules (XLCMs) are obtained by tethering two flexible end A-blocks and two flexible side B-blocks to a rigid backbone (R). A rich array of ordered st…
Stability of diverse dodecagonal quasicrystals in T-shaped liquid crystalline molecules
Xin Wang, An-Chang Shi, Pingwen Zhang +1
Quasicrystals are intriguing ordered structures characterized by the lack of translational symmetry and the existence of rotational symmetry. The tiling of different geometric unit…
Phase behavior of symmetric diblock copolymers under 3D soft confinement
Zhijuan He, Jin Huang, Kai Jiang +1
The phase behavior of symmetric diblock copolymers under three-dimensional (3D) soft confinement is investigated using the self-consistent field theory. The soft confinement is rea…
Theory of polygonal phases self-assembled from T-shaped liquid crystalline molecules
Zhijuan He, Xin Wang, Pingwen Zhang +2
Extensive experimental studies have shown that numerous ordered phases can be formed via the self-assembly of T-shaped liquid crystalline molecules (TLCMs) composed of a rigid back…
