Abstract

In this work, starch-based porous cryogels with controlled mechanical and electrical properties were prepared for tissue engineering applications. The starch cryogels were formulated using κ-carrageenan, poly(vinyl alcohol) (PVA), and styrylpyridinium-substituted PVA (SbQ) into the composite. A conductive cryogel was polymerized by chemical oxidation of 3,4-ethylenedioxythiophene (EDOT) using iron(III) p-toluenesulfonate as a strategy to control the electrical properties. The physical, thermal, and mechanical properties were evaluated for the obtained composites. Macro- and nanoscale results confirmed the capability of tuning the mechanical properties of the material by the addition of biopolymers in different contents. The presence of κ-carrageenan significantly increased the storage modulus and decreased the damping effect in the formulations. The presence of PVA showed a plasticizing effect in the formulations, confirmed by the buffering effect and an increase in storage modulus. PVA-SBQ improved the mechanical properties by cross-linking. The addition of PEDOT increased the mechanical and electrical properties of the obtained materials.

摘要

在这项工作中，制备了具有可控机械和电学性能的淀粉基多孔冷冻凝胶用于组织工程应用。淀粉冷冻凝胶是通过将κ-卡拉胶、聚乙烯醇（PVA）和苯乙烯基吡啶鎓取代的PVA（SbQ）配制成复合材料而制备的。使用对甲苯磺酸铁通过3,4-乙撑二氧噻吩（EDOT）的化学氧化聚合制备导电冷冻凝胶，以此作为控制电学性能的策略。对所得复合材料的物理、热学和力学性能进行了评估。宏观和纳米尺度的结果证实了通过添加不同含量的生物聚合物来调节材料机械性能的能力。κ-卡拉胶的存在显著提高了储能模量并降低了配方中的阻尼效应。PVA的存在在配方中表现出增塑作用，这通过缓冲效应和储能模量的增加得到证实。PVA-SBQ通过交联改善了机械性能。添加PEDOT提高了所得材料的机械和电学性能。
