Abstract(#br)This work aims at evaluating poly(2,6-diphenyl- p -phenylene oxide) (Tenax TA), in the form of thin films, as an adsorbent material for various analytical applications. The physical properties of the polymer were studied with regard to surface topography, crystal structure, and thermal stability. Films deposited from solution at different substrate temperatures were studied and compared to the granular form of the polymer. It was found that Tenax TA deposited from solution have a different topography compared to their granular counterpart.

摘要\n可伸缩和灵活的电子设备可以穿在人体上,也可以融入服装。它们在可穿戴电子、柔性显示器和可伸展电路领域有很好的应用前景。这里报道了一种基于多壁碳纳米管( MWCNTs )包复氧化锌( ZnO )纳米颗粒( NPs )并嵌入聚二甲基硅氧烷的智能传感器。基于MWCNT / ZnO纳米杂化粒子的智能传感器可以测量较宽的温度范围( 0 ~ 100℃),MWCNT浓度和ZnO NP尺寸的选择使得传感器对温度变化和其他变形表现出稳定的线性响应,具有较高的选择性。该智能传感器具有负温度系数,灵敏度为-33.6 kΩ℃-1,采用不同尺寸的ZnO NP测量传感器的弯曲运动灵敏度,可调谐范围为33.3 ~ 138.89 kΩ度-1。
