中文摘要:

在过去的十年,对在多样的应用的传导性的 hydrogels 激发了的高力量的迫切需要把 hydrogels 的改进机械性质与传导性的表演相结合的一个不停的努力。在这个工作,传导性的 hydrogels 与分子间的氢加强了结合的高力量被制作由在 poly 混合的 situ (2-vinyl-4,6-diamino-1,3,5-triazine-co-polyethylene 乙二醇 diacrylates )(PVDT-PEGDA ) hydrogels 与 poly (3,4-ethylenedioxythiophene )-poly(styrenesulfonate)(PEDOT/PSS ) 。deionized 水里的传导性的 hydrogels 分别地在 7.589.52 MPa 和 0.481.20 MPa 的范围与压缩力量和张力的力量展出高机械的表演,它被归功于到结合的分子间的氢在网络的 diaminotriazine-diaminotriazine (DAT-DAT ) 的相互作用。同时,增加 PEDOT/PSS 能显著地增加 hydrogels 的特定的传导性和平衡水内容。传导性的 hydrogels 可以有的这些 cytocompatible 要用作电的刺激的一个大潜力应答的软 biomaterials。

英文摘要:

Over the past decades, the urgent need for high strength conductive hydrogels in diverse applications has motivated an unremitting effort to combine the improved mechanical properties of hydrogels with conductive performances. In this work, high strength conductive hydrogels intensified with intermolecular hydrogen bonding are fabricated by in situ mixing poly(2-vinyl-4,6-diamino-1,3,5-triazine-co-polyethylene glycol diacrylates)(PVDT-PEGDA) hydrogels with poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT/PSS). The conductive hydrogels in deionized water exhibit high mechanical performances with compressive strength and tensile strength in the range of 7.58-9.52 MPa and 0.48-1.20 MPa respectively, which are ascribed to the intermolecular hydrogen bonding interactions of diaminotriazinediaminotriazine(DAT-DAT) in the network. Meanwhile, adding PEDOT/PSS can significantly increase both the specific conductivities and equilibrium water contents of the hydrogels. These cytocompatible conductive hydrogels may have a great potential to be used as electrical stimuli responsive soft biomaterials.
