Static charges on optical anti-counterfeiting membranes may lead to materials structural changes, dust stain aggravation, and misreading of optical information. Incorporating conductive particles is a common way to transfer accumulative charges, but the key issue is how to achieve high dispersion and effective distribution of particles. According to the strategy of assembly-induced structural colors, cellulose nanocrystals (CNCs) were employed as a solid emulsifier to stabilize hydrophobic carbon nanoparticles (CNPs) in aqueous media; subsequently, by solvent-evaporation-modulated co-assembly under a condition of 30 °C and 20 RH%, the binary suspensions containing 2 wt% CNC and CNPs with the equivalent concentration relative to CNC ranged from 1:40 to 1:10 were used to prepare antistatic composite membranes. Surface chemistry regulation of CNCs was applied to optimize the dispersibility of CNPs and the orientation of assembled CNC arrays, and the hydrophilic CNCs were more favorable for dispersion and assembly of binary suspension systems. Meanwhile, one-dimension carbon nanotube (CNT) and zero-dimension carbon black (CB) were found to show better dispersibility than two-dimension graphene, which was verified by a semiquantitative theoretical study. Moreover, the stable binary systems of CNT/CNC and CB/CNC were chosen for co-assembly as membranes, and the uniaxial orientation could be optimized as the full-width of 9.8° at half-maximum deviation angle while the surface resistivity could also drop down to 3.42 × 10² Ω·cm·cm⁻¹. The structural color character of such paper-homology and antistatic-integrated membranes contributes to optical information hiding-and-reading, and shows great potential as optical mark recognition materials for electrostatic discharge protective packaging and anti-counterfeiting applications.

光学防伪膜上的静电荷可能会导致材料结构变化，灰尘污点加剧以及光学信息误读。掺入导电粒子是转移累积电荷的常见方法，但关键问题是如何实现粒子的高度分散和有效分布。根据组装引起的结构色的策略，纤维素纳米晶体（CNCs）被用作固体乳化剂来稳定水性介质中的疏水性碳纳米颗粒（CNPs）。随后，通过在30°C和20 RH％的条件下进行溶剂蒸发调节的组装，将含有2 wt％CNC和CNP且相对于CNC的当量浓度为1:40至1:10的二元悬浮液制成用于制备抗静电复合膜。应用CNCs的表面化学调节来优化CNP的分散性和组装的CNC阵列的方向，亲水性CNCs更适合于二元悬浮系统的分散和组装。同时，一维碳纳米管（CNT）和零维炭黑（CB）被发现比二维石墨烯具有更好的分散性，这已通过半定量理论研究得到证实。此外，选择了稳定的CNT / CNC和CB / CNC二元体系共组装为膜，可以将单轴取向优化为半最大偏离角处9.8°的全宽，同时表面电阻率也可以优化。下降到3.42×10 亲水型CNC更适合二元悬浮体系的分散和组装。同时，一维碳纳米管（CNT）和零维炭黑（CB）被发现比二维石墨烯具有更好的分散性，这已通过半定量理论研究得到证实。此外，选择稳定的CNT / CNC和CB / CNC二元体系共组装为膜，可以优化半轴偏角时单轴取向为9.8°的全宽，同时表面电阻率也可以优化。下降到3.42×10 亲水型CNC更适合二元悬浮体系的分散和组装。同时，一维碳纳米管（CNT）和零维炭黑（CB）被发现比二维石墨烯具有更好的分散性，这已通过半定量理论研究得到证实。此外，选择了稳定的CNT / CNC和CB / CNC二元体系共组装为膜，可以将单轴取向优化为半最大偏离角处9.8°的全宽，同时表面电阻率也可以优化。下降到3.42×10² Ω·厘米·厘米^-1。这种纸同源性和抗静电结合膜的结构颜色特征有助于光学信息的隐藏和读取，并显示出作为用于静电放电防护包装和防伪应用的光学标记识别材料的巨大潜力。
