摘要：
Communication optical cables in extreme environments such as submarine cables and tundra require the use of metal/plastic composite tapes that can resistant to extreme environmental applications. However, there are still industrial challenges with stainless steel/plastic composite tape interfaces that are difficult to bond. Herein, C5 and C9 petroleum resins grafted with maleic anhydride (C5- g- MAH, C9- g- MAH) were successfully prepared by melt grafting and introduced into ethylene- acrylic acid copolymer/linear low density polyethylene (EAA/LLDPE) blended system and hot laminated with stainless steel tape, and when the content of C5-g-MAH is 30 phr, the peel strength of stainless steel plastic composite tapes is the best, reaching 28.6 N/cm and 15.2 N/cm before and after immersion test, respectively. The contact angle test show that C5-g-MAH could effectively reduce the surface tension between the blends and stainless steel, and promote the metal surface adhesion. Differential scanning calorimetry and melt rheological behavior show that C5-g-MAH can be fully miscible with EAA/LLDPE, while lowering the melting temperature of the blend, activating the molecular chain segments, increasing the wettability of stainless steel and increasing the bonding sites, which greatly improve the interfacial adhesion between EAA/LLDPE film and stainless steel. © 2024 Sichuan University.
