硫醇-烯/丙烯酸酯形状记忆聚合物可作为神经电极的基质,用于治疗神经功能障碍。神经电极被植入体内,以改变或记录脉冲传导。本研究对硫醇烯/丙烯酸酯聚合物进行了表征,以确定哪种合成方法构成了神经植入物的理想基质。为了在50到56.5°C之间获得所需的玻璃化转变温度,对固化条件、聚合物厚度、单体比例和吸水率进行了检查和控制。动态力学分析和热重分析表明,由至少50mol%丙烯酸酯含量组成的薄型硫醇烯/丙烯酸酯聚合物,在365 nm下固化至少1h,有望成为神经电极的基质。
Thiol-ene/acrylate shape-memory polymers can be used as base substrates for neural electrodes to treat neurological dysfunction. Neural electrodes are implanted into the body to alter or record impulse conduction. This study characterizes thiol-ene/acrylate polymers to determine which synthesis methods constitute an ideal substrate for neural implants. To achieve a desired Tg between 50 and 56.5 °C, curing conditions, polymer thickness, monomer ratios, and water uptake were all examined and controlled for. Characterization with dynamic mechanical analysis and thermal gravimetric analysis reveals that thin, thiol-ene/acrylate polymers composed of at least 50 mol % acrylate content and cured for at least 1 h at 365 nm are promising as substrates for neural electrodes.
