Front Cover: In article number 2000296 by Syed Wazed Ali, Bipin Kumar, and co‐workers, a higher electroactive phase (≈66%) is obtained for melt extruded shape memory polyurethane/polyvinylidene fluoride blend filaments without poling. Incorporation of optimum concentration of reduced graphene oxide (0.3%) into the blend leads to better compatibility and energy harvesting capabilities (VOC ∼ 349 mV). Promising shape memory properties (100% recovery, 46% fixity) can pave the way for fi lament‐integrated wearables as sensors and actuators.

利用聚偏氟乙烯和聚氨酯的熔融挤出复合长丝中的形状记忆耦合压电特性

封面：Syed Wazed Ali，Bipin Kumar和他的同事在编号为2000296的产品中，熔融挤出的形状记忆聚氨酯/聚偏二氟乙烯共混物长丝没有极化就可获得更高的电活性相（≈66％）。将最佳浓度的还原氧化石墨烯（0.3％）掺入共混物中可产生更好的相容性和能量收集能力（VOC〜349 mV）。有前途的形状记忆特性（100％恢复，46％固定性）可以为与细丝集成的可穿戴设备作为传感器和执行器铺平道路。
