A hydrosoluble light-sensitive polymer named PSAG (poly-styrenesulfonate acrylic acid glycidyl methacrylate) was synthesized by acrylic acid (AA), sodium 4-styrenesulfonate (SS), and glycidyl methacrylate (GMA). PSAG is used to modify multiwall carbon nanotubes (MWCNTs) with a length diameter between 0.004 and 0.016. An inkjet conductive ink was formed by well-dispersed MWCNTs in aqueous and organic solvents, which could adjust the surface tension and viscosity of the ink. Gas sensors were then fabricated using this conductive ink on a household inkjet printer. The sensors demonstrated good reproducibility and acceptable recovery time (<200 s) to ammonia, methanol, and acetone. The resistance of the inkjet-printed sensor electrodes remained stable in the process of bending the sensors to different angles because of ultraviolet curing.
一种名为PSAG（聚苯乙烯磺酸盐丙烯酸缩水甘油酯甲基丙烯酸酯）的水溶性光敏聚合物由丙烯酸（AA）、对苯乙烯磺酸钠（SS）和甲基丙烯酸缩水甘油酯（GMA）合成。PSAG用于修饰长度直径在0.004至0.016之间的多壁碳纳米管（MWCNT）。通过将MWCNT在水性和有机溶剂中充分分散形成喷墨导电油墨，该油墨可调节油墨的表面张力和粘度。然后使用这种导电油墨在家庭喷墨打印机上制造气体传感器。这些传感器对氨气、甲醇和丙酮表现出良好的重现性和可接受的恢复时间（<200秒）。由于紫外线固化，喷墨打印的传感器电极在将传感器弯曲到不同角度的过程中电阻保持稳定。
