The solution-processed gas barrier film was fabricated and used for organic field-effect transistors (OFETs). Organic-inorganic hybrid sol-gel materials and cyclic transparent optical polymer (CYTOP) were used as the bottom and top layers of the barrier films, respectively, to effectively protect against gas permeation through the barrier films. The organic-inorganic hybrid material includes sol-gel precursors and amphiphilic polymers. The conventional sol-gel precursors form siloxane bonds by sol-gel reaction and form densely-packed rigid part in thin films. The alkoxysilane-functionalized amphiphilic polymer in the sol-gel precursor solutions has two hydrophobic segments and a hydrophilic segment. The amphiphilic polymer with reactive alkoxysilane groups at both ends of the hydrophobic segments can be involved in the sol-gel reaction, and they can act as surfactants to surround the conventional precursors stabilizing the nanoparticles formed by the hydrolytic condensation reaction of precursors. The amphiphilic polymer also provides flexibility for hybrid sol-gel thin films. CYTOP was used to introduce hydrophobicity on top of the organic-inorganic hybrid thin films. The barrier films containing the organic-inorganic hybrid and hydrophobic CYTOP layers were applied to OFETs and exhibited notable gas barrier properties, high transparency, and flexibility. The encapsulated OFETs with 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS-pentacene) as an organic semiconductor showed a slight decrease in hole mobility from 0.13 to 0.11 cm² V^-1 s^-1, while the OFETs without barrier films showed a mobility decrease from 0.11 to 0.03 cm² V^-1 s^-1.

用于有机场效应晶体管的溶液处理的柔性阻气膜

制备了经过溶液处理的阻气膜，并将其用于有机场效应晶体管（OFET）。有机-无机杂化溶胶-凝胶材料和环状透明光学聚合物（CYTOP）分别用作阻挡膜的底层和顶层，以有效地防止气体透过阻挡膜。有机-无机杂化材料包括溶胶-凝胶前体和两亲聚合物。常规的溶胶-凝胶前体通过溶胶-凝胶反应形成硅氧烷键，并在薄膜中形成紧密堆积的刚性部分。溶胶-凝胶前体溶液中的烷氧基硅烷官能化的两亲聚合物具有两个疏水链段和一个亲水链段。在疏水链段两端带有反应性烷氧基硅烷基团的两亲聚合物可能参与溶胶-凝胶反应，它们可以充当表面活性剂来包围常规的前体，从而稳定由前体的水解缩合反应形成的纳米颗粒。两亲聚合物还为混合溶胶-凝胶薄膜提供了灵活性。CYTOP用于将疏水性引入有机-无机杂化薄膜的顶部。将包含有机-无机杂化层和疏水性CYTOP层的阻隔膜应用于OFET，并显示出显着的阻气性，高透明度和柔韧性。以6,13-​​双（三异丙基甲硅烷基乙炔基）并五苯（TIPS-并五苯）作为有机半导体封装的OFETs的空穴迁移率从0.13 cm轻微降低至0.11 cm CYTOP用于将疏水性引入有机-无机杂化薄膜的顶部。将包含有机-无机杂化层和疏水性CYTOP层的阻隔膜应用于OFET，并显示出显着的阻气性，高透明度和柔韧性。以6,13-​​双（三异丙基甲硅烷基乙炔基）并五苯（TIPS-并五苯）作为有机半导体封装的OFETs的空穴迁移率从0.13 cm轻微降低至0.11 cm CYTOP用于将疏水性引入有机-无机杂化薄膜的顶部。将包含有机-无机杂化层和疏水性CYTOP层的阻隔膜应用于OFET，并显示出显着的阻气性，高透明度和柔韧性。以6,13-​​双（三异丙基甲硅烷基乙炔基）并五苯（TIPS-并五苯）作为有机半导体封装的OFETs的空穴迁移率从0.13 cm轻微降低至0.11 cm² V ^-1 s ^-1，而没有阻挡膜的OFETs的迁移率从0.11降低到0.03 cm ² V ^-1 s ^-1。
