Transparent paper with excellent optical transmittance and mechanical stability shows potential for use in diverse applications as a substrate. Here, we reported a novel alkyd resin-impregnated cellulose transparent (ARICT) paper that exhibited good flexibility, adequate biodegradability, easy scale-up, and tailorable wettability. As the concentration of alkyd resin increased (5–15 wt %), the optical transmission of the cellulose paper increased from 70.7% to 93.5% at 550 nm, and its water contact angle increased from 9° to 91°. Furthermore, impregnating the cellulose paper with alkyd resin increased the surface smoothness, thermal stability, and toughness of the paper. After poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS) was coated on one side of the ARICT paper, a flexible single-sided conductive paper with high conductivity was obtained, while the other side retained high insulativity, suggesting that the ARICT paper was a promising substrate for the fabrication of a flexible electrode. Finally, the eco-friendly biodegradability was verified by subjecting the ARICT paper to fungal degradation over time. This study developed a new method for the fabrication of flexible and biodegradable substrates, enabling the development of disposable electronics.

用于可生物降解基材的可湿性可调的透明纸的简易制造
具有优异的光学透射率和机械稳定性的透明纸显示出了在多种应用中用作基材的潜力。在这里，我们报道了一种新型的醇酸树脂浸渍的纤维素透明（ARICT）纸，该纸具有良好的柔韧性，足够的生物降解性，易于放大和可调节的润湿性。随着醇酸树脂浓度的增加（5-15 wt％），纤维素纸在550 nm处的透光率从70.7％增加到93.5％，其水接触角从9°增加到91°。此外，用醇酸树脂浸渍纤维素纸增加了纸的表面光滑度，热稳定性和韧性。将聚（3,4-乙撑二氧噻吩）/聚（苯乙烯磺酸盐）（PEDOT：PSS）涂布在ARICT纸的一侧后，获得了具有高电导率的柔性单面导电纸，而另一面却保持了高绝缘性，这表明ARICT纸是制造柔性电极的有前途的基材。最后，通过使ARITC纸随时间推移而发生真菌降解，从而验证了生态友好型生物可降解性。这项研究开发了一种用于制造柔性和可生物降解基板的新方法，从而使一次性电子产品得以发展。
