Hydroxypropyl methylcellulose (HPMC), a FDA approved water-soluble cellulose derivative, has played as a binder in a variety of applications in construction products, paints, and drug delivery. In spite of these many applications of HPMC as a binder, its adhesion mechanism is not well understood. In this study, we measured adhesion characteristics of HPMC in different hydrophobicity, water content, and temperature. The adhesion of HPMC were not affected by surface hydrophobicity in both bulk compression test and nano-mechanical test by surface forces apparatus, but strongly influenced by temperature and water content. The results indicate water content and temperature are critical variable for the adhesion of HPMC to inorganic surfaces. As adhesive and coating technologies have shifted towards environmentally friendly systems, these results provide a starting point for the fabrication of HPMC-based composites for a variety of future applications. |
