Abstract
The present application discloses a composition, an adhesive film including the composition and a chip packaging structure. The composition includes epoxy resin, a surfactant, a curing agent and filler, wherein the surfactant is selected from a modified hexafluoropropylene compound. The surfactant in the composition is the modified hexafluoropropylene compound, the modified hexafluoropropylene compound is lower in surface energy, good in water resistance and oil resistance and capable of effectively lowering the surface tension of the composition, and therefore, when being used for preparing the adhesive film, the composition is higher in coating wettability. In, addition, the composition has stronger chemical cleaning resistance, and in a process that a residual solder flux obtained in a soldering process of a chip is cleaned, a chip protection film prepared from the composition has stronger cleaning resistance to an alkaline solution so as not to be easy to fall off.
