A selective adhesive mechanism comprises an engineered surface structure or substrate and a compliant member. The compliant member is able to be a dry and non-tacky substance. The compliant member is selectively adhesive to the engineered surface when the compliant member is in contact with the engineered surface. The compliant member shows adhesion to the engineered surface when the compliant member is within a pre-selected range of hardness. In some embodiments, the compliant member comprises a polymeric member, a thermoplastic elastomer, silicone, polyurethane, or a combination thereof.

A method for producing a cellulose and/or synthetic fibre-based support of which at least one surface is coated with a layer containing at least one water-soluble polymer comprising: hydroxyl or primary-secondary amino functional groups, at least some of which have been functionalized beforehand with at least one organic compound comprising at least one epoxy functional group, and at least one R.sup.1 group wherein R.sup.1 is a vinyl functional group or at least one Si(R.sup.2).sub.3 functional group and wherein R.sup.2=hydrogen atom, hydroxyl, alkoxy, alkyl, and combinations thereof.

A process for manufacturing a putter with a bi-material shaft is disclosed herein. The putter comprises a putter head, the bi-material shaft, a mass member and a grip. The bi-material shaft comprises a body with a tip end and a butt end. The body comprises a metal section extending from the tip end to a connection point, and a composite section extending from the butt end to the connection point. The mass member is positioned within an opening at the butt end of the shaft. Mass from the shaft is transferred to the club head and the mass member in the butt end of the shaft.

Aspects of the present disclosure generally describe polyarylether ketones and methods of use. In some aspects, a composition includes one or more polymers of formulae (I), (II), or (III):

Embodiments of the present invention relate generally to methods of treating metal surfaces to enhance adhesion or binding to substrates, and devices formed thereby. In some embodiments of the present invention, methods of achieving improved bonding strength without roughening the topography of a metal surface are provided. The metal surface obtained by this method provides strong bonding to resin layers. The bonding interface between the treated metal and the resin layer exhibits resistance to heat, moisture, and chemicals involved in post-lamination process steps, and therefore can suitably be used in the production of PCB's. Methods according to some embodiments of the present invention are especially useful in the fabrication of high density multilayer PCB's, in particular for PCB's having circuits with line/spacing of equal to and less than 10 microns. Methods according to other embodiments of the present invention are particularly useful in the coating of metal surfaces in a wide variety of applications.

A latent elastic film laminate is provided including a film predominantly comprising olefin elastomers. The film is stretched and maintained in a stretched state in order to impart the desired level of latent elasticity such that the conditioned film laminate will shrink upon activation, such as by heating. The latent elastic film laminate can be advantageously used in the manufacture of various elasticated articles, including absorbent personal care articles, by activating the latent elasticity after attachment to the article and thereby shirring and elasticizing components to which the film laminate is attached.

Disclosed is a method for preparing an acrylic rubber roll. The method includes mixing and stirring 50-77 wt % 2-ethylhexyl acrylate, 2-10 wt % acrylic acid, 20-40 wt % 2-hydroxyethyl acrylate, and 0.1-0.5 wt % curing agent at room temperature to form a mixture; adding 0.1-0.2 wt % photoinitiator into the mixture, and continuing to stir until the photoinitiator is fully dissolved in order to form an acrylic composition; irradiating the acrylic composition with UV light to crosslink and cure the acrylic composition in order to obtain an acrylic tape; and cutting the acrylic tape according to a size of a plastic rubber roll shaft, and evenly sticking the acrylic tape to a freely-rotatable rubber roll while avoiding air bubbles so as to obtain the acrylic rubber roll.
