In this work a novel top-down approach for the synthesis of macroporous PDMS (mpPDMS) sponges decorated with pristine multiwalled carbon nanotubes (CNTs) is presented. The mpPDMS-CTN sponges are subjected to different characterizations aimed at investigating morphological, mechanical, and electrical properties of this novel porous semi- conducting material. The mpPDMS-CNT sponges are then used to prepare low cost conductometric pressure/strain sen- sors with high performance in terms of large dynamic range (strain 0-80%, pressure 0-1.22 kPa), low limit of detection (strain 0.01%, pressure 0.14 Pa), limited electrical and mechanical hysteresis (max value of 17.7 and 16%, respectively at strain of 60%), good reliability.

Abstract
In this work a novel top-down approach for the synthesis of macroporous PDMS (mpPDMS) sponges decorated with pristine multiwalled carbon nanotubes (CNTs) is presented. The mpPDMS-CTN sponges are subjected to different characterizations aimed at investigating morphological, mechanical, and electrical properties of this novel porous semi- conducting material. The mpPDMS-CNT sponges are then used to prepare low cost conductometric pressure/strain sen- sors with high performance in terms of large dynamic range (strain 0-80%, pressure 0-1.22 kPa), low limit of detection (strain 0.01%, pressure 0.14 Pa), limited electrical and mechanical hysteresis (max value of 17.7 and 16%, respectively at strain of 60%), good reliability.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
