Dense and Square Lattice-Free Colloid Crystals of Highly-Charged Monodisperse Latex Particles on 3-Aminopropyl Trimethoxysilane-Modified Glass Substrate |
| 초록 |
2- and 3-dimensional colloid arrays are fabricated using highly-charged monodisperse poly (styrene/sodium p-styrene sulfonate) particles and 3-aminopropyl trimethoxysilane (APTMS)-modified glass substrate at 20oC. The 2- and 3-dimensional arrays on the APTMS-modified glass substrate show denser packing patterns with no crevices, as compared with those of cleaned bare glass substrates. This dense packing pattern is explained by the nature of APTMS-coated surface leading to ‘free-slipping’ of incoming particles and stronger capillary force due to the hydrated and hairy surface of the particles at the water meniscus, and which leads to substantial particle deformation and hexagonal close packing. These arrays of deformed particles in the first layer then act as a template for further growth through multilayer deposition following the same packing pattern. |
