Abstract Thermosensitive hydrogels have enormous potential, e.g. in sensors, actuators, microfluidics or drug delivery systems. In these applications the tuneability of their response rate is a key parameter and is therefore of great interest. However, the applicability of these systems is subject to limitations, which may be overcome by enhanced nanocomposite materials. This paper presents a systematic study of the thermal response of graphene oxide (GO) – and carbon nanotube (CNT) – poly(N-isopropylacrylamide) composite systems, and investigates the effect of the nanoparticle filler content, both on the nanoscale and the macroscopic level. While the equilibrium swelling properties of the different nanocomposites are only slightly influenced, the kinetics of the response of the swelling medium following an abrupt temperature increase from 20 to 40 or 50 °C can vary within wide limits depending on the type or the amount of nanoparticle loading, as well as on the temperature difference.

基于 PNIPAM 的纳米复合材料的结构和响应度之间的相关性：纳米和宏观尺度的结合

摘要 热敏水凝胶具有巨大的潜力，例如在传感器、执行器、微流体或药物输送系统中。在这些应用中，响应速度的可调谐性是一个关键参数，因此引起了人们的极大兴趣。然而，这些系统的适用性受到限制，这可以通过增强的纳米复合材料来克服。本文系统研究了氧化石墨烯 (GO) - 和碳纳米管 (CNT) - 聚（N-异丙基丙烯酰胺）复合系统的热响应，并研究了纳米颗粒填料含量对纳米尺度和宏观的影响。等级。虽然不同纳米复合材料的平衡溶胀性能仅受到轻微影响，
