Abstract Biodegradable polyurethanes foam as well as foam strips have been formulated by the renowned one-shot process. Commercially available biodegradable trifunctional polyol, polycaprolactone triol (major, ~77 wt%) and isophorone diisocyanate were chosen to react in the presence of other essential components to formulate the PU foams from the paper cup as well as foam strips using mould at ambient temperature. The formulation of foams has been efficiently attempted by successive steps by alteration of the components such as chain extender, quantity of water and isocyanate index. In situ addition of fullerenes (0.1, 0.4 and 1.0 wt%) into the composition of PU foam strips formulation in mould found to afford the three samples of PU-fullerenes nanocomposite. In case of polyurethanes-fullerenes nanocomposite foam strips, nanomaterial of fullerenes was identified to disperse uniformly in the bulk of sample to incorporate the enhancement in physicochemical and mechanical properties value as compared to the control PU foam strip. The battery of analyses such as physicochemical, morphological and mechanical properties was studied for each foam samples, including control and PU-fullerenes nanocomposite strips. Solid state carbon-13 nuclear magnetic resonance spectral data for the foam revealing desired properties was collected to corroborate the chemical functional groups in the molecular structure network.

一次性成型的可生物降解聚氨酯泡沫和泡沫富勒烯纳米复合条：物理化学和机械性能

摘要 可生物降解的聚氨酯泡沫和泡沫条采用著名的一次性工艺配制而成。选择市售的可生物降解的三官能多元醇、聚己内酯三醇（主要，~77 wt%）和异佛尔酮二异氰酸酯在其他基本成分的存在下进行反应，以在环境温度下使用模具从纸杯和泡沫条中配制 PU 泡沫。通过改变诸如增链剂、水量和异氰酸酯指数等组分的连续步骤，已经有效地尝试了泡沫的配制。发现在模具中将富勒烯（0.1、0.4 和 1.0 wt%）原位添加到 PU 泡沫条配方的组合物中，以提供三个 PU-富勒烯纳米复合材料样品。在聚氨酯-富勒烯纳米复合泡沫条的情况下，发现富勒烯纳米材料均匀分散在大量样品中，与对照 PU 泡沫条相比，物理化学和机械性能值有所提高。对每种泡沫样品（包括对照和 PU-富勒烯纳米复合材料条）进行了一系列分析，如物理化学、形态学和机械性能。收集揭示所需性质的泡沫的固态碳 13 核磁共振光谱数据，以证实分子结构网络中的化学官能团。研究了每个泡沫样品的形态和机械性能，包括对照和 PU-富勒烯纳米复合材料条。收集揭示所需性质的泡沫的固态碳 13 核磁共振光谱数据，以证实分子结构网络中的化学官能团。研究了每个泡沫样品的形态和机械性能，包括对照和 PU-富勒烯纳米复合材料条。收集揭示所需性质的泡沫的固态碳 13 核磁共振光谱数据，以证实分子结构网络中的化学官能团。
