8ysz陶瓷复合材料和原位石墨化纳米纤维素
陶瓷基质复合材料（CMC）的8摩尔型Yttria-stabilized氧化锆（8ysz）与天然纤维纳米纤维素（0.75、1、2 wt％）混合在一起，由Spark等离子体烧结（SPS）制备。纳米纤维素明显改善了8YSZ陶瓷基质的致密化，并诱导了明显的晶粒尺寸细化。证明，在SPS加工过程中，纳米纤维素的原位石墨化导致6 nm薄的涡流石墨层同质覆盖8ysz陶瓷晶粒。通过电阻抗光谱法分析了介电性能，表明接近或低于≈1.6vol％石墨的低渗透阈值在上面，高于该阈值，而混合的离子电子传导占主导地位。CMC在还原条件下（5％H 2 /Ar at-Mosphere）至少稳定，直到800°C，高电导率为σDC= 0.17 SCM - 1，即使在900°C（8YSZ-2％CNF）也是如此。这些特征使8ysz-Nanocellulose CMC有望在中高温电化学设备中应用。
