“…Nanocomposite adhesives based on specialty thermoplastic matrices, such as polyaryletherketone (PAEK), polyetheretherketone (PEEK), and polyetherketoneketone (PEKK), etc., are gaining a lot of attention [8][9][10][11][12]. Various NPs such as MWCNTs [13], Silicon carbide (SiC) [14,15], Boron Nitride (BN) [10,16,17], Titanium Carbide (TiC) [12], etc., have been recently successfully tried in combination with thermoplastics. In our recent work on exploring the potential of MWCNTs in various amounts in PAEK [11], a 152% improvement in LSS was due to significant bulk strengthening (increased tensile strength) and chemical functionality.…”

This study encompasses the development of sandwich-structured adhesive reporting the synergism in the functioning of two kinds of nanoparticles (NPs)-SiC (Silicon carbide) and MWCNTs (multiwalled carbon nanotubes). Two adhesives using MWCNTs and NPs of SiC in selected amounts were developed using Polyaryletherketone (PAEK) thermoplastic polymer as a base matrix. Fabricated joints using these adhesives were characterized for dispersion of NPs, lap shear strength (LSS), and failure modes. Based on the data on the LSS, the pros and cons of using individual NPs were analyzed, and the third adhesive was designed in a sandwich manner, where positive points of both the NPs were expected to work synergistically. The sandwich adhesive showed higher LSS than the individual ones. It was concluded that the strengthening mechanism of MWCNTs of bulk polymer in the central portion was beneficial. The two outer layers of SiC NPs in PEAK interacting with the two steel surfaces of coupons proved helpful in increasing friction and, hence, synergistically increasing the LSS of sandwich adhesive.
