Janus-型纤维素瓶刷根据接枝-自和接枝-至方法结合点击化学合成。通过尺寸排阻色谱结合多角度激光光散射（SEC-MALLS）分析表征溶液中的分子构象，表明瓶刷产品在不同溶剂中采用各种构象，形成半圆柱体。这些材料在开发新型表面活性剂、乳液稳定剂、Langmuir-Blodgett膜或纳米载体等方面具有广阔的应用前景。
Janus‐type cellulosic bottlebrushes were synthesized according to grafting‐from and grafting‐to approaches in combination with click chemistry. The molecular conformation in the solution was characterized by size‐exclusion chromatography combined with multi‐angle laser‐light scattering (SEC‐MALLS) analysis, indicating the bottlebrush products to adopt various conformations in different solvents, forming hemicylinders. The materials are promising, for instance, in the development of novel surfactants, stabilizers for emulsions, Langmuir–Blodgett films or nanocarriers.
