The cellulose ether, sodium carboxymethylcellulose (SCMC), has long been used in England as an all-purpose adhesive, consolidant, and sizing agent, while its conservation use in the United States has been limited. Compared to methylcellulose, it is a better adhesive, and in some conservation treatments, may be preferred to both methylcellulose and starch paste due to its unique properties. The ...

Liquid crystal polymer (LCP) and silicone adhesives are widely used in electronics manufacturing. The integrity of the adhesion between the two materials is crucial to the reliability of electronic products, however, the adhesion mechanism and associated reliability has not been thoroughly understood. In this paper, the adhesion mechanism between a commonly used LCP and a silicone adhesive is e...

Several molluscs have been shown to alternate between a non-adhesive trail mucus and a similar gel that forms a strong glue. The major structural difference between the two secretions is the presence of specific proteins in the adhesive mucus. The present study identifies similar proteins from the glue of the slug Arion subfuscus and the land snail Helix aspersa. To investigate the role played ...

Introduction Marine mussels are known to secrete unique adhesive proteins that form strong bonds with various substrates in the presence of water.1 These mussel adhesive proteins (MAPs) are secreted as fluids and can undergo rapid curing to form adhesive plaques in a wet environment. The presence of the unusual amino acid 3,4-dihydroxyphenylalanine (DOPA) in MAPs is believed to impart strong ad...

A novel high-strength nano-adhesive is demonstrated for fabricating nano- and microfluidic devices. While the traditional plasma sealing methods are specific for sealing glass to poly(dimethylsiloxane) (PDMS), the new method is compatible with a wide variety of polymeric and inorganic materials, including flexible substrates. Additionally, the traditional method requires that sealing occur with...

The adhesive pads of geckos provide control of normal adhesive force by controlling the applied shear force. This frictional adhesion effect is one of the key principles used for rapid detachment in animals running up vertical surfaces. We developed polypropylene microfibre arrays composed of vertical, 0.3 microm radius fibres with elastic modulus of 1 GPa which show this effect for the first t...

Results are reviewed from a study on the distribution of surfactants in pressure-sensitive adhesive (PSA) films subsequent to the coating process. The PSAs are water-based acrylics synthesized with n-butyl acrylate, vinyl acetate and methacrylic acid and two commercially available surfactants, disodium (nonylphenoxypolyethoxy)ethyl sulfosuccinate (anionic) and nonylphenoxypoly(ethyleneoxy) etha...

Axisymmetric vibration of an infinite Pyrocomposite circular hollow cylinder made of inner and outer pyroelectric layer of 6mm-class bonded together by a Linear Elastic Material with Voids (LEMV) layer is studied. The exact frequency equation is obtained for the traction free surfaces with continuity condition at the interfaces. Numerical results in the form of data and dispersion curves for th...

Polymer-based materials are commonly used as an adhesion layer for bonding die chip and substrate in micro-system packaging. Their properties exhibit significant impact on the stability and reliability of micro-devices. The viscoelasticity, one of most important attributes of adhesive materials, is investigated for the first time in this paper to evaluate the long-term drift of micro-accelerome...

The development of new surfaces, highly sticky and conducting, is a great challenge in the field microdevices fabrication, more precisely for 3D assembly microcomponents. Such surfaces were prepared by electrochemical deposition polyaniline films. films from phosphoric acid solution adhesive than ones obtained other acids. Indeed, adhesion H3PO4 was found to be high (> 1 µN) stable time, as sho...
