Thermally degradable adhesives with cellulose and related methods of manufacture and use

 

Highlights

An adhesive is a substance that binds contact surfaces together and resists separation. Some adhesives can be difficult to impossible to remove without damaging the contact surface. This innovation describes a novel adhesive containing one or both of cellulose micro or nanocrystals (CNC) and provides heating methodologies that enable this new adhesive to degrade in a way that allows for its easy removal and the separation of adjacent parts.
