With the ‘Synergistic Effects’ such as ‘Bridging’ and ‘Intercalating’ between fillers with different morphologies, we can get the CF/CNTs/NanoG filled polyacrylate electrically conductive adhesives (ECA). Through the study, we found that the comprehensive properties of the electrically conductive PSA reach the best when the composite fillers are made up of CF 3wt%、NanoG 5wt% and CNTs 5wt%. The conductivity of the electrically conductive PSA reaches 3.0×10-2 S/cm, the 180o peel strength is 0.38KN/m and the shear strength is 0.42MPa.

Natural rubber (SMR L grade), epoxidized natural rubber (ENR) 25 and 50 were loaded with hybrid tackifiers consisting of a mixture of coumarone-indene and gum rosin. The coumarone-indene was fixed at 40 parts per hundred of rubber (phr) while the concentration of gum rosin was varied from 20 to 80 phr. The viscosity, peel and shear strength of the adhesives prepared from the elastomers was studied. Results show that peel strength exhibits a maximum value at 60 phr gum rosin for SMR L-based adhesive while for ENR 25 and ENR 50 based adhesives a maximum value is observed at 40 phr gum rosin which was attributed to the occurrence of optimum wettability and compatibility at this tackifier loading. Meanwhile, viscosity and shear strength decreases with increasing gum rosin concentration. SMR L-based adhesive consistently exhibits higher viscosity and shear strength whereas ENR 25-based adhesive steadily shows higher value for all modes of peel tests.

This study develops hot melt pressure sensitive adhesives (HMPSAs) for the seamless bonding of nylon fabric, using butyl acrylate as the main monomer material and mixing the functional monomer for polymerization. It is combined with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide for the photoinitiator and ultraviolet irradiation is used to make a pre-polymer. The effects of butyl acrylate content, type of functional monomer, and 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide content on the molecular weight of acrylate pre-polymer are discussed, following the Taguchi method. The pre-polymer is then mixed with the reactive diluent glycidyl methacrylate blend and with 2-10phr diphenyl (2,4,6-trimethylbenzoyl) phosphine oxide, coated on a release film, irradiated by ultraviolet light, and cured into hot melt pressure sensitive adhesives. The adhesive properties of hot melt pressure sensitive adhesive bonding on nylon include the peel strength, the shear strength, adhesive warpage, adhesive color difference, and adhesive overflow, which are discussed following the Taguchi method and the elimination and choice translating reality method for multi-quality analysis. Hot melt pressure sensitive adhesives are implemented by optimization parameters for practical validation. The results show that the peel strength of hot melt pressure sensitive adhesives is 1.495 kg/cm, the shear strength of hot melt pressure sensitive adhesives is 14.326 kg/cm2, adhesive warpage is 0.93 mm, adhesive color difference is 1.66, and adhesive overflow is 0.97 mm. The performance of HMPSAs in this study is enhanced effective.
