采用自洽场理论（SCFT）模拟研究了ABC线性三嵌段共聚物/纳米粒子在选择性溶剂中共组装形成具有凸起表面的多隔室杂化结构的过程。三维SCFT模拟结果表明，杂化形貌取决于接枝链的长度和数目，而凸起的数目和形状依赖于纳米粒子的尺寸；接枝链长度和数目对杂化形貌具有等效影响。计算结果表明，熵在共组装过程中比焓更为重要。

Co-assembly of ABC linear triblock copolymer/nanoparticle into bump-surface multicompartment hybrids in selective solvent was studied through self-consistent field theory (SCFT) simulation. Results from three-dimensional SCFT simulation showed that the hybrid morphology depended on the length and number of grafted chains, whereas the number and shape of bumps relied on nanoparticle size. The simulation results also showed that the length and number of grafted chains had an equivalent effect on hybrid morphology. Calculated results indicated that entropy was a more important factor than enthalpy in the co-assembly.
