AB  - Arrangements of cationic starches hydrophobized by acetylation (CS-acet) 
      deposited from aqueous electrolyte solutions onto hydrophilized and hydrophobized 
      silica surfaces were investigated by atomic force microscopy (AFM), X-ray 
      photoelectron spectroscopy (XPS), and contact angle measurements. The influence 
      of electrolyte composition, acetylation degree of cationic starch (DS(ACET)), and 
      deposition method was examined. On a hydrophobic substrate, CS-acet formed an 
      open film with structure strongly dependent on DS(ACET) and electrolyte 
      composition of the solution. On a hydrophilic substrate, acetylation increased 
      the hydrophobicity of the film when the starch was deposited by adsorbing. When 
      deposition was made by spin coating, i.e., the CS-acet was forced onto the 
      substrate, the hydrophobic tuning by acetylation was lost. The films deposited by 
      spin coating were thicker and considerably rougher than those deposited by 
      adsorbing.
