Abstract

The conformational folding/unfolding behaviors of DNA supercoils serve as a fundamental mechanism governing ultradense bio-information storage and precise genetic transcription. Mimicking those nanoscale dynamic conformational behaviors for macroscopic materials to achieve unusual functionalities will be of great interest but remains unexplored. Herein, a DNA-inspired materials evolution paradigm is presented to create multifunctional supercoiled conformational fibers (SCFs) by programmed twisting controlled self-buckling. Through the programmed twist-stress modulation, a low-density polyethylene strip is transformed into high-performance DNA-like SCF through a unique multiscale microstructure evolution process. This DNA-like SCF exhibits five hallmark characteristics unattainable before, including ultra-large elastic deformability (900 ± 50%), metal-level mechanical strength (330 ± 30 MPa), unprecedented torsional energy-storage density (16.1 ± 0.6 kJ kg⁻¹), torsional energy release upon appropriate stimulations, and impact buffering through conformation-mediated energy-dissipation. Characterization reveals that these unexpected energy-related properties mainly are contributed by the multiscale twisting-reinforced microstructures and conformation mechanics. Potential applications of the SCFs are demonstrated finally by harvest-and-storage of wind energy and soft-landing. The DNA-like SCFs indicate a general platform for materials evolution with extraordinary mechanics and functions.

程序扭曲的材料进化：dna启发的超强超卷曲构象纤维的储能和缓冲

DNA超级线圈的构象折叠/展开行为是控制超密集生物信息存储和精确基因转录的基本机制。模拟这些宏观材料的纳米级动态构象行为以实现不寻常的功能将是非常有趣的，但仍未被探索。本文提出了一种dna启发的材料进化模式，通过程序扭曲控制自屈曲来创建多功能超卷曲构象纤维（SCFs）。通过程控扭应力调制，低密度聚乙烯条通过独特的多尺度微观结构演化过程转化为高性能的类dna SCF。这种类似dna的SCF具有5个以前无法实现的特征，包括超大弹性变形能力（900±50%）、金属级机械强度（330±30 MPa）、前所未有的扭转能量存储密度（16.1±0.6 kJ kg−1）、适当刺激时的扭转能量释放，以及通过构象介导的能量耗散来缓冲冲击。表征表明，这些意想不到的能量相关特性主要是由多尺度扭曲增强的微观结构和构象力学贡献的。最后通过风能的收集和储存以及软着陆来论证超临界燃料系统的潜在应用。类dna SCFs是一种具有非凡力学和功能的材料进化的通用平台。
