Minature versions of Hookean springs can be built from single-handed helical ladder polymers. The spring constants of these molecular springs vary with the helix diameter analogous to classical springs. These new molecular springs provide an alternative mechanism of expansion/contraction controlled by the intrinsic helical geometries of the ladder polymers, which do not unfold under tension unlike more common flexible polymers.

具有不同弹簧常数的螺旋分子弹簧

Hookean 弹簧的微型版本可以由单手螺旋阶梯聚合物制成。这些分子弹簧的弹簧常数随螺旋直径而变化，类似于经典弹簧。这些新的分子弹簧提供了一种由梯形聚合物的固有螺旋几何形状控制的膨胀/收缩的替代机制，与更常见的柔性聚合物不同，梯形聚合物不会在张力下展开。
