Monte Carlo simulations were carried out to investigate the adsorption of semiflexible chains from a semidilute solution to substrates with periodic stripes of width w . The chains are made of fused N = 10 monomers of diameter σ interacting with each other through excluded volume interactions and with the stripes via a square‐well potential of depth ε and width σ . The surface coverage was found to increase upon increasing the chain stiffness and decreases on increasing the width of the stripes. At small w , more flexible chains are adsorbed than stiff chains. Analysis of the radius of gyration for the chains showed that when w < 8 σ , the component along the stripe direction is significantly larger than the others. Orientational order parameter reveals that, for small w , chains have preference to align along the stripe direction.
