The electrically conductive pressure-sensitive composite adhesives based on acrylic polymer and silver-coated inorganic particles have been investigated in this article. The electrical conductivity of the pressure-sensitive adhesives containing silver coated spherical inorganic particles is lower at the same concentration of the filler in comparison with silver coated inorganic fibers, the strength of adhesive joint to aluminum being higher in the case of the pressure-sensitive adhesive containing silver-coated inorganic fibers. After the thermal treatment the strength of adhesive joint to aluminum of electrically conductive pressure sensitive adhesives increases significantly. The suitable concentration proposition of the silver-coated inorganic filler in the pressure-sensitive adhesive requires a compromise solution of the problem taking into account the ultimate adhesive and electrical properties of the investigated pressure-sensitive adhesives composites. 相似文献

A prototype pressure-sensitive adhesive that has a low refractive index (<1.36) and is optically clear has been developed (Holguin and Chang, US Patent 6703463, 2002). The refractive index is a key feature in the application of optical polymers, and this pressure-sensitive adhesive is particularly useful for light-transmitting devices. It is a fluoro-substituted mono-acrylate adhesive. Fluoro-polymers are known to have a low refractive index, but typically the fluoro-polymers are not sticky and are opaque because of their crystallinity. The design of this novel fluorosubstituted monoacrylate adhesive polymer is based on the rheological marriage of fluoro-polymers and pressure-sensitive adhesives. 相似文献

If the tack of a pressure-sensitive adhesive is closely related to the rolling motion of a ball on the material, it is more scientific to express tack in terms of the rolling friction coefficient, which depends on the physical properties of the materials, and not on any trivial conditions of measurements. It is shown that the rolling friction coefficient of a pressure-sensitive adhesive can experimentally be determined from the pulling cylinder method much more easily than the rolling ball method and that we can theoretically calculate the rolling friction coefficient by making some assumptions, concerning deformation and failure of a pressure-sensitive adhesive. 相似文献
