摘要

聚对苯二甲酸乙二醇酯(PETG)是一种难以纺丝的材料，以前没有论文报道过制造PETG网的正确条件。为了解决这一问题，对PETG在不同溶剂体系下的溶解度和电可纺性进行了初步研究，并建立了tea图来选择理想的溶剂体系。在此基础上，采用由二氯甲烷(DCM)和三氟乙酸(TFA)组成的高挥发性二元溶剂体系制备了电纺PETG纤维。结果首次证明了PETG静电纺丝网能够支持黄锈病孢子的接种和萌发，从而证实了PETG是用于制造农业生物传感器的理想材料。最佳溶剂配比为85/15 (DCM/TFA)。

Electrospinning polyethylene terephthalate glycol

Polyethylene terephthalate glycol (PETG) is a difficult-to-spin material, and no previous papers have reported the correct conditions to create PETG meshes. To address this issue, a preliminary study on the solubility and electrospinnability of PETG using a range of solvent system was conducted and a Teas graph was established to select the ideal solvent system. Based on these preliminary results, electrospun PETG fibers were produced using a highly volatile binary solvent system consisting of dichloromethane (DCM) and trifluoroacetic acid (TFA). Produced meshes were extensively characterized, and the results demonstrated for the first time the ability of electrospun PETG meshes to support the inoculation and germination of yellow rust spores, thus confirming that PETG is an ideal material to be used for the fabrication of agriculture biosensors. The results also showed that the best solvent split was 85/15 (DCM/TFA).
