Abstract
Colorful: enabled by their reduced capacity for chain entanglement, high-molecular-weight brush block copolymers can rapidly self-assemble to photonic crystals. The blending of two polymers of different molecular weight can predictably modulate the sizes of the polymer domains, giving rise to a facile means of precision tuning of these photonic-band-gap materials.
摘要
高分子量刷状嵌段共聚物由于其链缠结能力降低，能够快速自组装成光子晶体。两种不同分子量聚合物的共混可以预测性地调节聚合物畴的尺寸，从而为这些光子带隙材料的精确调谐提供了一种简便的方法。
