Abstract

Cold sintering is an emerging technology that significantly reduces sintering temperatures by approximately an order of magnitude, down to about 100–200°C. This reduction of processing temperature enables the co-sintering and integration of dissimilar materials, such as ceramics and polymers, into unprecedented composites, where the low-energy consumption densification provides an opportunity for recycling. Here, we cold sintered barium titanate (BaTiO3)-polytetrafluoroethylene (PTFE) ceramic-polymer composites, demonstrating that nano-sized PTFE polymer powders facilitate co-sintering and enable the recycling of ceramic composites. This approach offers an opportunity for reusing and re-processing ceramic components, thereby promoting sustainability through waste reduction and energy savings.

纳米级聚合物辅助陶瓷复合材料的冷烧结和回收利用
冷烧结是一种新兴技术,可将烧结温度大幅降低约一个数量级,降至 100-200°C 左右。加工温度的降低使陶瓷和聚合物等异种材料能够共同烧结并集成到前所未有的复合材料中,低能耗的致密化为回收利用提供了机会。在这里,我们对钛酸钡(BaTiO3)-聚四氟乙烯(PTFE)陶瓷-聚合物复合材料进行了冷烧结,证明了纳米级聚四氟乙烯聚合物粉末可促进共烧结并实现陶瓷复合材料的回收利用。这种方法为陶瓷部件的再利用和再加工提供了机会,从而通过减少废物和节约能源促进可持续发展。
