发明详述
如图1-3中所示，公开了由一种或多种绝缘聚合物和一种或多种离子液体形成的半导体材料10。这种半导体材料10可以通过用一种或多种离子液体掺杂一种或多种绝缘聚合物来合成。半导体材料10可以在众多不同的应用中使用，包括但不限于传感器和存储装置。

合并的绝缘聚合物和离子液体可以形成薄膜12。薄膜12可以具有预定厚度。半导体材料10可以由受控温度下以可控厚度挤出的一种或多种绝缘聚合物和一种或多种离子液体形成。半导体材料10可以从一种或多种绝缘聚合物和一种或多种离子液体形式形成一种或多种纤维。可以通过用一种或多种离子液体掺杂一种或多种绝缘聚合物来合成半导体材料10，其功能在图1和图3中显示。
半导体材料10可以由按重量计至多达10%的离子液体以及剩余的所述聚合物形成，并且更具体地，可以是按重量计0%和5%之间的离子液体以及剩余的所述聚合物。将离子液体通过以下方式添加至绝缘聚合物：在水或有机溶剂中溶解绝缘聚合物并且向这种混合物添加一种或多种离子液体。可以将所得混合物搅拌1-30分钟。在另一个实施方式中，一种或多种离子液体可以与一种或多种熔融的绝缘聚合物混合。可以将离子液体添加至聚合物熔体并且随后可以将熔体流延成薄膜。相对于绝缘材料而言添加的离子液体的百分比取决于需要在半导体中获得的电导率水平。例如，PVA/PAA和0.1甘油的混合物提供高电导率。
在至少一个实施例中，如图2中所显示，可以使用半导体材料10以形成能够存储数据的存储装置14。存储装置14可以由安置在第一侧面20上的第一绝缘层18和第二侧面24上的第二绝缘层22之间的导电层16形成，所述第二侧面24位于整体上与所述第一侧面20相对的侧面上。导电层16可以是但不限于碳纳米管（CNT）、氧化锌或金。存储装置14也可以包括与第一绝缘材料18的外表面30连接的半导体薄膜层28。半导体薄膜层28可以是挠性的并且可以至少部分地由聚乙酸乙烯酯（PVA）组成。可以将半导体薄膜层28沉积在该装置上以充当半导体层。第一绝缘层18可以由有机材料形成。在至少一个实施方式中，第一绝缘层18可以由聚甲基丙烯酸甲酯有机材料形成。第二绝缘层22可以由有机材料形成。在至少一个实施方式中，第二绝缘层22可以由聚甲基丙烯酸甲酯有机材料形成。
