We report herein a self-adaptive surface-initiated bimetal-mediated controlled radical polymerization (SI-BMCRP) for fabricating various polymer brushes using microliter volumes under ambient conditions. The introduction of bimetal CuZn alloy can self-adaptively control the dissociation of copper species while still realizing the controllability of polymer brush growth with high oxygen tolerance at a wide range of distances between the bimetal alloy and the initiator-modified substrate. The successful fabrication of multiscale and multifunctional polymer brushes with high-end group fidelity and patterned architectures further demonstrates the robust nature of SI-BMCRP. The resultant polymer brushes show great potential for new applications in moisture-enabled electricity generation, breath monitoring, and speech recognition.
我们在此报告一种自适应表面引发的双金属介导的可控自由基聚合（SI-BMCRP），用于在环境条件下使用微升体积制备各种聚合物刷。双金属CuZn合金的引入可以自适应地控制铜物种的解离，同时在双金属合金与引发剂修饰的底物之间的广泛距离范围内，仍能实现具有高氧耐受性的聚合物刷生长的可控性。成功制备具有高端基保真度和图案化结构的多尺度和多功能聚合物刷，进一步证明了SI-BMCRP的稳健性。所得的聚合物刷在湿气发电、呼吸监测和语音识别等新应用中显示出巨大潜力。
