What is Adhesion Properties of a Thermoplastic Olefin Elastomer Grafted with Maleic Anhydride Under Ozone about?

The adhesion properties of a thermoplastic olefin elastomer (TPO), surface-grafted with maleic anhydride (MA) under ozone exposure, were analysed. TPO samples were dip-coated with maleic anhydride (MA) that was mixed with one of the initiators benzophenone (BP), benzoyl peroxide (BPO), or azoisobutyronitrile (AIBN) before being exposed to ozone. The adhesion properties of the TPO samples after ozone exposure were analysed by attenuated total reflection infrared spectroscopy (ATR-IR), lap shear tests and contact angle measurements. ATR-IR spectra confirmed that the amount of grafted MA increased with the ozone exposure time and changed with the type of initiator used. The grafted MA greatly improved the lap shear strength (LSS) of the TPO in TPO/epoxy adhesive/steel laminates. The LSS also depends on the initiator applied. The total and the polar component of the surface energy of the MA-grafted TPO increased after ozone exposure, following the order AIBN a BPO a BP, while the lap shear strength increased in the order of BP a AIBN a BPO after long time ozone treatment. The specimen grafted using BPO as initiator has the greatest LSS. ZUSAMMENFASSUNG: TPO-Proben wurden mit einer Misc
