Abstract
Composite adhesives composed of emulsion-based acrylic pressure sensitive adhesives (Em-PSA) and a small amount of single-walled carbon nanotubes (SWCNT) were prepared in water system by the assistance oftwo dispersants，carboxymethyl cellulose sodium salt and rutin. Optical microscopic observation revealed that the dispersants markedly improved the dispersion of SWCNT. Transmission electron microscope and electrical resistance measurement indicated that SWCNT were located at the interface between emulsion particles and constructed the conductive network in the Em-PSA composites at 0.43phr or more of SWCNT loading to the polymer solid content. SWCNT also reinforced the weak interfacial regions between emulsion particles，and resultantly peel creep resistance and shear strength of the composites were improved at high temperature.
