Statistical theory of the compensating effect when anchoring with two orthogonal photoaligned polymers.

Article Synopsis
- The paper investigates how polymer films are influenced by two different polymerization processes happening either simultaneously or one after the other, focusing on their anchoring properties.
- It explains a compensating effect observed when using two orthogonal polymerization methods, detailing how the anchoring energy is calculated from changes in Helmholtz free energy in a defined interface layer.
- The findings include a mathematical expression that accounts for the angular orientation of the photoaligning processes and proposes a method for achieving controlled anchoring strength during fabrication.
