论文摘要
通用互动，例如库仑或其他长期范围的径向对称排斥相互作用在半柔性聚合物的珠子弹簧模型之间诱导最初直的聚合物链中的不稳定性，以形成长期的生存的螺旋结构。这种机制可以解释刚性（生物）聚合物中螺旋的自发出现，因为链的有效电荷增加。螺旋形成与化学无关，并且不使用扭转电位。因此，该方法可用于在NM-10 $μ$的长度尺度上合成螺旋弹簧。
Generic interactions e.g. the Coulomb or other long ranged radially symmetric repulsive interactions between monomers of bead-spring model of a semi-flexible polymer induce instabilities in a initially straight polymer chain to form long lived helical structures. This mechanism can explain the spontaneous emergence of helices in stiff (bio-)polymers as effective charge of the chain increases. The helix formation is independent of the chemistry and torsional potentials are not used. So this method can be used to synthesize helical springs at length scales of nm-10$μ$.
