We demonstrate in this work the practical use of naturally extracted waxes of plant and animal origin, , beeswax, carnauba wax, rice bran wax, lanolin wax, and two shellac waxes as dielectrics in organic field effect transistors (OFETs). We present a thorough characterization of their material properties, processability and film forming characteristic, surface characterization, dielectric investigation and the fabrication of field effect transistors with two classic organic semiconductors, , pentacene and fullerene C. We show that operating voltages as low as 1 V are possible for all the OFETs using blade coating as fabrication method of waxes solubilized in their appropriate solvent, chloroform or -octane. Although in general difficult to process in thin films, we demonstrate in this work the practical applicability of these natural waxes for electronics fabrication.
在本研究中，我们展示了天然提取的动植物源蜡（蜂蜡、巴西棕榈蜡、米糠蜡、羊毛脂蜡和两种紫胶蜡）在有机场效应晶体管（OFET）中作为电介质的实际应用。我们全面表征了它们的材料特性、可加工性和成膜特性、表面特性、介电性能，并使用两种经典有机半导体（并五苯和富勒烯C）制造了场效应晶体管。我们表明，使用刮刀涂布法将蜡溶解在其合适的溶剂（氯仿或正辛烷）中制备的所有OFET，其工作电压低至1V。尽管这些天然蜡通常难以制成薄膜，但我们在本研究中证明了它们在电子制造中的实际适用性。
