Synthetic and natural nanomaterials with self-propelling mechanisms continue to be explored to boost chain mobility beyond normal reptation in the crowded environments of entangled chains. Here we employ scaling theory and numerical simulations to demonstrate that activating one chain end of a singular or isolated chain boosts entanglement-constrained chain reptation from the one-dimensional diffusive mobility as described by the de Gennes–Edwards–Doi model to ballistic motion along the entanglement tube contour. The active chain is effectively screened from the constraint of entanglements on length scales exceeding the tube size.

纠缠的筛选限制：自推进端诱导弹道链爬行的作用

继续探索具有自推进机制的合成和天然纳米材料，以在纠缠链的拥挤环境中提高链的移动性，使其超越正常的爬行。在这里，我们采用缩放理论和数值模拟来证明激活单个或孤立链的一个链端可以促进纠缠约束链从 de Gennes-Edwards-Doi 模型描述的一维扩散流动性到沿弹道运动的运动。纠缠管轮廓。有效地从超过管尺寸的长度尺度上的缠结约束中筛选出活性链。
