ABSTRACT

To widen the type and scope of use of shape memory polymers (SMPs), we added hindered phenol (AO-80) to nitrile–butadiene rubber (NBR) to gain a group of AO-80/NBR rubber composites. The glass transition temperature (Tg), structure, mechanical properties, and shape memory properties of the AO-80/NBR rubber composites were characterized. It was concluded that the dispersion of AO-80 in the NBR matrix was homogeneous and intra-molecular hydrogen bonds were formed between the hydroxyl groups (OH) of AO-80 and the cyano groups (CN) of NBR molecular chain. The dosage of AO-80 added could be changed to tune the Tg. AO-80/NBR rubber composites revealed outstanding shape fixity and shape recovery. The method for tuning the Tg of AO-80/NBR rubber composites will provide an idea for the fabrication and design of new SMPs. © 2020 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48911.
