Abstract or Summary
  • Advancing contact angles formed by water and aqueous ethanol solutions were measured on both bare surfaces and film-covered surfaces of acrylic, glass, hydrophilic and hydrophobic silicon, polycarbonate, polyester, and stainless steel. Each bare surface was initially characterized with respect to its hydrophilic - hydrophobic balance. Both protein films and milk films were prepared on each surface; the adsorbed mass comprising each film was measured with ellipsometry. Contact angle methods proved useful in detecting the presence of a protein film on sufficiently hydrophilic or sufficiently hydrophobic surfaces. Contact angle methods were also found to be useful for detecting the presence of a milk film on sufficiently hydrophilic solid surfaces. The results also indicated that the type of diagnostic liquid chosen for the analysis becomes an important factor for films of increasing complexity. In any event, contact angle analysis is inappropriate to quantify the actual mass of soil remaining on a solid surface.
