纤维素纳米纤维基抗冻双网络凝胶的制备及其应变传感性能研究
Preparation of Cellulose Nanofiber-based Antifreeze Double Network Gel and Its Strain Sensing Properties
摘要
Abstract
In this study,a deep eutectic solvent(DES)was prepared by ethylene glycol(EG)and zinc chloride(ZnCl₂),and it was used as sol-vent replacing water.Acrylamide(AM)was used as a monomer,and polyacrylamide(PAM)was polymerized under UV irradiation.Then,the cellulose nanofiber(CNF)and polyvinyl alcohol(PVA)were introduced to enhance mechanical properties,resulting in a DES-PVA/PAM/CNF antifreeze double network gel.The results showed that the prepared DES-PVA/PAM/CNF antifreeze double network gels exhibited the best antifreeze performance with freezing point as low as-73.03℃when the molar ratio of ZnCl2 to EG was 1∶5.Further investigation of the effects of CNF content on the gel properties revealed that the best overall performances were achieved when the CNF content was 0.4%(based on the mass of EG).At normal temperature,the fracture strength of the gel was up to 0.94 MPa,and the strain at break was 844.5%,at low temperature,the fracture strength was still maintained at 0.92 MPa,exhibiting excellent adaptability at low temperatures.In addition,after assembling the gel as a strain sensor,the monitoring of human skin-attached motion was successfully realized.关键词
