摘要:
具有多孔结构的传感材料因可赋予器件轻质、高柔性以及穿着舒适性等优点,已成为近年来的研究热点。以聚氨酯(PU)乳胶粒作为皮克林(Pickering)粒子,引入氧化石墨烯(GO)作为导电填料,制备“水包油(O/W)”型的高内相乳液(HIPE)液态模板;将乳液模板经冷冻干燥成型后,以抗坏血酸(VC)还原成型材料中的GO,得到具有压阻响应性的柔性导电聚合物泡沫(rGO@PU)。分别考察了PU粒子浓度以及GO浓度对rGO@PU形貌、力学性能以及压阻性能的影响。结果表明:PU可用作Pickering粒子,稳定“环己烷/水”HIPE,同时PU低的玻璃化转变温度赋予材料柔性;随着PU粒子浓度的降低,材料孔径增大,模量降低;提高GO浓度,材料孔径变化不大,但模量增高;材料的灵敏度、应力量程则可通过改变PU和GO的浓度进行调控。
