(NCP) particle arrays have potential applications
in many fields such as photonics and sensors. However, due to thermodynamic
stability, it is still a challenge to produce NCP arrays by the traditional
approach. Here, we demonstrated a facile method to fabricate hexagonal
close-packed (HCP) arrays with different orientations from that of
the Janus particles. After that, the HCP arrays can be easily tuned
by stretching deformation of polyethylene film. By tuning the stretching
elongations, NCP arrays with five Bravais lattice structures were
obtained. Besides, to fabricate the complex structure, these arrays
were used as templates to assemble binary particle arrays. Such tunable
crystal lattice and binary self-assembly crystal can be useful for
fabricating more flexible structures and more open systems.
