A composite dry adhesive includes (a) an adhesive layer comprising a shape memory polymer and (b) a resistive heating layer comprising a shape memory polymer composite on the adhesive layer. The shape memory polymer composite includes conductive particles dispersed in a shape memory polymer matrix, where the conductive particles have a concentration sufficient to form a conductive path through the resistive heating layer.

An adhesive article is described comprising a foamed adhesive layer and a non-foamed adhesive layer. The adhesive of each adhesive layer comprises a tetrahydrofurfuryl (meth)acrylate copolymer; an epoxy resin; a polyether polyol; and optionally a hydroxy-functional film-forming polymer. The adhesive may be used in structural and semi-structural bonding applications and is designed to fail cohesively.

The invention relates to a method for producing a single-sided adhesive film (1). Said method consists of providing a support layer (2) and coating a first side of the support layer (2) with an adhesive film (3), a lubricant coating (4) is applied to a second side of the support layer (2), the support layer (2) being in the form of a polyester film. Said method is characterised in that the polyester film, prior to bonding to the adhesive layer (3), and the lubricant coating (4) is treated with trichloroacetic acid, sodium persulphate, iron chloride or copper chloride in order to increase the surface energy of the polyester film. The invention also relates to a one-sided adhesive film (1) produced according to the above-mentioned method.

A method for surface preparation of composite substrates prior to adhesive bonding. A curable surface treatment layer is applied onto a curable, resin-based composite substrate, followed by co-curing. After co-curing, the composite substrate is fully cured but the surface treatment layer remains partially cured. The surface treatment layer may be a resin film or a removal peel ply composed of resin-impregnated fabric. After surface preparation, the composite substrate is provided with a chemically-active, bondable surface that can be adhesively bonded to another composite substrate to form a covalently-bonded structure.

Flexible films of thermosetting adhesive materials which are non-tacky to the touch are storage stable at room temperature and can be cured at elevated temperature with a short cure time and can be cured to produce a tough flexible adhesive layer including bonding to oily surfaces. the materials are particularly useful in bonding together dissimilar substrates.

A lightweight electromagnetic wave shielding tape is disclosed. The tape includes a first polymer protective layer, a calendered conductive material layer coupled to a bottom side of the first polymer protective layer, and a second polymer protective layer coupled to a bottom side of the conductive material layer so that the conductive material layer is encapsulated within the protective layers. An adhesive layer can also be applied to one of the protective layers.

The present invention relates to a method for producing a single-sided adhesive film (1) for securing a load, comprising providing a backing layer (2) and coating a first side of the backing layer (2) with an adhesive layer (3), wherein a plastic (4) is applied to a second side of the backing layer (2) in order to form a non-slip surface on the adhesive film (1). Moreover, the present invention relates to a single-sided adhesive film (1) produced by the above method.

The present disclosure is drawn to an adhesive printable film. The film can include a polymeric film substrate, an image receiving layer, and an adhesive layer. The polymeric film substrate can have a first side and a second side, and can be transparent or translucent. The image receiving layer can be applied on the first side and can include a crosslinked polymeric network and polymeric particles dispersed therein. The peelable adhesive layer can be applied on the second side and can include a continuous matrix polymer having adhesive particles and plastic particles dispersed therein.

A swelling tape for filling a gap, a method of manufacturing the swelling tape for filling a gap, a method of filling a gap, an electrode assembly and a secondary battery are provided. For example, the swelling tape can be applied inside a gap in which a fluid exists so as to fill the gap by becoming a 3D form, and can be useful at anchoring a subject in which the gap is formed, as necessary.
