Durable nanocomposite adhesives based on polyacrylates and surface-modified colloidal silica

Surface-modified colloidal silica (M-CS) nanoparticles were successfully synthesized from colloidal silica (CS) and methyltrimethoxysilane using sol–gel method and characterized by Fourier transform-infrared spectroscopy. Both CS and M-CS were then incorporated into acrylic adhesives. M-CS particles in 2-ethoxyethanol had similar particle size to pure CS based on the characterization by DLS. The morphologies of M-CS particles in acrylic adhesives examined by TEM showed more homogeneous dispersities than that of pure CS which were aggregated and phase separated in acrylic adhesives. In addition, the thermal properties of the nanocomposite acrylic adhesives determined by thermogravimetric analyses and differential scanning calorimetry showed higher glass transition temperature and thermal properties than pure acrylic adhesives. Finally, the 180° peel strength of nanocomposite acrylic adhesives was higher than pure adhesives with improved durabilities.

Comparison of fracture behavior between acrylic and epoxy adhesives

An experimental study was conducted on the strength of adhesively bonded steel joints, prepared epoxy and acrylic adhesives. At first, to obtain strength characteristics of these adhesives under uniform stress distributions in the adhesive layer, tensile tests for butt, scarf and torsional test for butt joints with thin-wall tube were conducted. Based on the above strength data, the fracture envelope in the normal stress-shear stress plane for the acrylic adhesive was compared with that for the epoxy adhesive. Furthermore, for the epoxy and acrylic adhesives, the effect of stress triaxiality parameter on the failure stress was also investigated. From those comparison, it was found that the effect of stress tri-axiality in the adhesive layer on the joint strength with the epoxy adhesive differed from that with the acrylic adhesive. Fracture toughness tests were then conducted under mode l loading using double cantilever beam (DCB) specimens with the epoxy and acrylic adhesives. The results of the fracture toughness tests revealed continuous crack propagation for the acrylic adhesive, whereas stick-slip type propagation for the epoxy one. Finally, lap shear tests were conducted using lap joints bonded by the epoxy and acrylic adhesives with several lap lengths. The results of the lap shear tests indicated that the shear strength with the epoxy adhesive rapidly decreases with increasing lap length, whereas the shear strength with the acrylic adhesive decreases gently with increasing the lap length.     

A Method to Evaluate Water Resistance of Acrylic Adhesives

A number of two-part acrylic adhesives were examined for the effect of immersion time in water at 23°C, 80°C and 100°C on the tensile lap shear strength. The mechanism of acrylic bonded joint failure in water was discussed based on the observed results. The relative water resistance between these adhesives was compared from shear strength retention values. The dependence of the water resistance of these adhesives at 23°C and at elevated temperatures was discussed. It has been found that for acrylic adhesives, the water resistance at room temperature can be evaluated on the basis of the shear strength retention values after aging in water at 80°C.

UV/heat dual‐curable adhesive tapes for fabricating stacked packages of semiconductors

To facilitate the fabrication of a reliable stacked package for a semiconductor, UV/heat dual curing of adhesives was investigated. The formulated adhesives contained acrylic monomer and epoxy resins. First, UV curing was conducted on the acrylic monomer, followed by heat curing. It was found that UV‐curable acrylic monomers affected the adhesive's properties, e.g., adhesion, water absorption, and viscoelasticity. As the acrylic monomer, neopentylglycol diacrylate (NPGDA), trimethylolpropane triacrylate (TMPTA), dipentaerythritol hexaacrylate (DPHA), and tricyclodecanedimethanol acrylate (TCDDA) were used to investigate the effect of functional group numbers and structure. As a result, an acrylic monomer that has two functional groups with a rigid moiety (TCDDA) showed acceptable properties as adhesives for the fabrication, and thus a UV/heat‐curing adhesive has been successfully developed. © 2008 Wiley Periodicals, Inc.
