Shape memory polymers
Abstract:
Shape memory polymer (SMP) is a smart material which can maintain deformed
temporary shape and can recover to its original shape upon an external stimulus such as
temperature, moisture and pH. In this work, a renewable natural resource based on eugenol
and furfurylamine was used to substitute phenol and amine from petroleum based reactants to
provide green polybenzoxazine. Mechanical, thermal and shape memory properties of the
green polybenzoxazine/epoxy alloys were evaluated by a dynamic mechanical analyzer,
thermogravimetric analyzer and a shape recovery test. It was observed that the content of
benzoxazine (E-fa) in aliphatic epoxy (NGDE) to exhibit good shape memory performance
was in a range of 30 to 50wt%. With an increase in E-fa content, glass transition temperature,
degradation temperature at 5% weight loss, and storage modulus of the E-fa/NGDE alloy
increased providing the greatest values of 51 °C, 283 °C, and 4.84 GPa, respectively. The
poly(E-fa)/NGDE alloy SMP also exhibited a high shape fixity and recovery ratio of greater
than 90%. Such results indicated that the poly(E-fa)/NGDE alloy is a good candidate for a
low stimulating temperature shape-memory polymer.
