    摘要: The invention relates to novel curable bio-based thermosetting compositions of a) at least one highly-functional bio-based epoxy resin; and b) at least one carboxylic acid crosslinker selected from the group consisting of a water-soluble multifunctional carboxylic acid, a dicarboxylic acid oligomer from a melt reaction between a diol and a dicarboxylic acid or its anhydride, and mixtures thereof and which are curable with water, an alcohol or a water and alcohol mixture. The bio-based thermosets of the invention may be free of VOCs and/or organic solvents. The bio-based thermosets of the invention can be used to form coatings, composites, adhesives, and films. Methods of making the bio-based thermosets of the invention are disclosed as are coating compositions and coated objects, such as coatings, composites, adhesives, and films, using the bio-based thermosets of the invention.

    摘要: Switchable adhesion devices, systems and methods are provided. A switchable adhesion component includes a switchable body. At least one portion of the body is adapted to carry an adhesive layer and another portion a load. At least a portion of the body is switchable between one or more varying states without imparting change to the surface chemistries or area at the adhesive joint.
