“…Therefore, the lamination of Al foils with polymer films such as polypropylene (PP) and polyethylene (PE) have been investigated to enhance their performance. The laminated polymers efficiently protect the Al surface from damages that decrease the protective ability of the Al foil [6][7][8][9][10][11][12][13][14][15]. In particular, such polymer-based Al-foil laminates have been studied as a soft packaging material for lithium-ion batteries.…”

The adhesion between aluminum (Al) foil and cast polypropylene (CPP) film laminated with mixtures of amorphous- and crystalline-maleic anhydride-grafted ethylene-propylene-diene monomer (MAH-g-EPDM) rubbers and highly reactive polybutene (HRPB) as the adhesives was investigated. Specifically, the HRPB was used as an adhesion promoter of the MAH-g-EPDM rubbers and CPP as well as a compatibilizer of two kinds of MAH-g-EPDM rubbers having limited miscibility. To introduce strong chemical bonds between the MAH-g-EPDM rubbers and Al foil, the surface of Al foil was treated with 3-aminopropyl triethoxysilane (APTES). The weak adhesion between Al foil and MAH-g-EPDM rubbers was improved by imidization between the amine groups (–NH2) of APTES and the maleic anhydride groups (MAH) of MAH-g-EPDM rubbers. The effects of the composition of adhesives, tempering time and adhesive thickness were also studied to optimize the adhesion of the CPP/Al foil laminates. We concluded that MAH-g-EPDM rubber based adhesives containing HRPB can be applied for the lamination of Al foil and CPP films to satisfy the requirements of high-performance packaging materials for various purposes.

“…To obtain a CPP-laminated Al foil with high durability, it is critical to achieve strong interfacial adhesion between the polymer layers and Al foil. Resins derived from polyurethane (PU) and epoxy resin (EP) have been widely used as adhesives as well as coating materials [8][9][10][11][12][13][14][15], which can be suitable candidates…”

“…From the results from contact angle measurement in Table 2, the chemically etched substrate has the lowest contact angle, an indication of excellent surface wettability since higher surface roughness promotes the better spreading of liquid to the substrate surface 9) . Furthermore, the open structure of voids or crevices on the surface contributes to a high tendency of the water to fill in and reduce contact angle 20) .…”

“…The main objective of this study is to investigate the effect of chemical treatment on the aluminum substrate surface towards the mechanical performance of the ECA, with varying MWCNT filler loading, in terms of the lap shear strength. Aluminium alloy is the substrate material of choice since this material is well-known for its useful applications in widespread industries from electronics to aerospace, automotive, general engineering [9][10][11] .…”

Adhesion strength of electrically conductive adhesive (ECA) could be enhanced through surface treatment. This paper characterizes the multiwalled carbon nanotube (MWCNT) filled ECA with varying MWCNT filler loading. Here, the focus is on the effect of chemical treatment on aluminium substrate surface treatment onto the adhesion strength of the ECA as per ASTMD 1002. The chemically etched aluminum substrate provides the largest effective bond area between ECA/substrate interface, with the highest shear strength of the ECA. More specifically, the ECA with 6 wt.% MWCNT filler loading exhibit an optimum lap shear strength, showing an adhesive-cohesive failure mode.

“…The current research [11,13,17,19,20] focuses on determining the effect of different methods of material surface preparation on the wettability, surface free energy and strength of adhesive joints made of thereby prepared material. However, neither the effect of surface free energy of the adhesive nor the impact of maintaining proper ratios of the surface free energy components between the bonded material and the adhesive are taken into consideration.…”

The paper reports values of surface free energy and its components of an epoxy adhesive modified by the addition of an active diluent. Wetting envelopes are determined and they serve as a basis for a wettability analysis and determining the possibility of maximizing the work of adhesion between the liquid and the solid. Static strength tests of adhesive joints made with the analysed adhesive compositions were also conducted. The results are used to determine the effect of active diluent addition on the energy and adhesive properties of the epoxy adhesive.
