Abstract Polycarbonate microcellular foam (PCMF) with novel “coral reef-like” structures have successfully developed to improve the mechanical properties. By incorporating green asphalt-based microporous organic polymer (AMOP) into polycarbonate (PC) via melting mixing, AMOP/PC achieved improvements in better compatibility, lower complex viscosity and higher Tg due to the lubricant and physical adsorption effects of AMOP. Then AMOP/PC microcellular foams were prepared via supercritical CO2 batch foaming. The good compatibility between AMOP and PC facilitated the formation of “coral reef-like” structures during the foaming process, ascribed to strong interfacial bond between AMOP and PCMF matrix. Due to the toughening and strengthening effects of “coral reef-like” structures, the impact and compressive strength of AMOP/PCMF with 1.5 wt% AMOP achieved 3.2 and 1.2 times increases when PCMF used as control. This study paved a facile approach to fabricate novel “coral reef-like” structures of microcellular foams and extended the application of asphalt-based microporous organic polymer.

通过沥青基微孔有机聚合物和超临界二氧化碳形成聚碳酸酯微孔泡沫的新型“珊瑚礁状”结构

摘要 具有新型“珊瑚礁状”结构的聚碳酸酯微孔泡沫 (PCMF) 已成功开发以提高机械性能。通过熔融混合将绿色沥青基微孔有机聚合物 (AMOP) 掺入聚碳酸酯 (PC) 中，由于 AMOP 的润滑和物理吸附作用，AMOP/PC 实现了更好的相容性、更低的复数粘度和更高的 Tg。然后通过超临界 CO2 间歇发​​泡制备 AMOP/PC 微孔泡沫。AMOP 和 PC 之间的良好相容性促进了发泡过程中“珊瑚礁状”结构的形成，这归因于 AMOP 和 PCMF 基质之间的强界面结合。由于“珊瑚礁状”结构的增韧和强化作用，AMOP/PCMF的抗冲击和抗压强度为1。当 PCMF 用作对照时，5 wt% AMOP 实现了 3.2 倍和 1.2 倍的增加。该研究为制造新型微孔泡沫“珊瑚礁状”结构铺平了道路，并扩展了沥青基微孔有机聚合物的应用。
