Binary Colloidal Alloy Test - 3

The BCAT-3 investigation aimed to exploit the long range ordered structures formed using the self-assembly of colloidal particles and demonstrate the use of colloid engineering to synthesize new materials with novel properties. The goal was to use a mixture of two different materials or binary alloys to greatly increase the flexibility of the resultant colloidal structures and qualitatively study the phase behavior and crystallization properties of these binary alloys. In addition, the investigation proposed to study the properties of mixtures of colloids and polymers where the addition of the polymer induces weak attractive interactions between the colloidal particles by the depletion mechanism, leading to a rich phase behavior for the colloidal
particles.

BCAT-3研究旨在借助胶体颗粒自组装形成的长程有序结构，验证胶体工程技术在合成具备新颖性能的新型材料中的应用价值。本研究的核心目标为采用两种不同材料（或二元合金）的混合物，大幅提升所得胶体结构的灵活性，并定性探究此类二元合金的相行为与结晶特性。此外，本研究还计划开展胶体与聚合物混合体系的性质研究：聚合物的添加可通过排空机制在胶体颗粒间诱导弱吸引相互作用，进而使胶体颗粒体系呈现出丰富的相行为。
