A complete classification for unbundling transitions of two semiflexible polymers and for desorption transitions of such polymers at planar surfaces is presented. The interaction potentials can depend both on the polymer/polymer (or polymer/surface) separation and on the orientation of the polymers. Using analytical transfer matrix methods and scaling arguments, the order of the transitions and the corresponding critical exponents are obtained for all types of interaction potentials in arbitrary spatial dimension . Our results are applicable to biopolymers or polyelectrolytes with large persistence lengths such as actin filaments, microtubules, or DNA.
