The paper introduces a model of polymer chains near a spherical defect. The reduced free energy dependences of the polymer associate on its width at different values of temperature are obtained. It is shown that the width of surface wrinkles increases with increasing defect size. The value of Young's modulus ratios of the polymer coating and the foundation is reconstructed from the width of the wrinkles. It is shown that with increasing defect size the Young's modulus of the coating increases and its corrosion resistance decreases. Keywords: polymer films, textured polymer coatings, defects, mechanical properties of polymer films, Young's modulus of polymer films.
