Abstract
In this research, polyester-based polymers/Fe3O4 nanocomposite foams were prepared in order to study their performance; namely shape recovery speed and actuation load. A foamed structure was obtained through a solid-state foaming process, which was studied and optimized in previous research. The optimum foaming parameters were applied in an attempt to achieve the highest foaming ratio possible. A Taguchi Map was then designed to determine the number of experiments to be conducted. The experimental results showed that the maximum actuation load obtained was 3.35 N, while optimal (fastest) recovery speed was 6.36 mm/min. Furthermore, temperature had no impact on the actuation load as long as a temperature above the Tg was applied. Moreover, the addition of nanoparticles reduced shape recovery speed due to discontinuity within the polymer matrix.
Highlights
Thethe original shape of aofmamaterial is recovered in the presence of a suitable stimulus such as heat, light, electric, or terial is recovered in the presence of a suitable stimulus such as heat, light, electric, or magnetic magneticfields fields[1]
The orthogonal array design in this research needs a total of 7 experiments, the nearest Taguchi array design is with 8 experiments, and Table 1 below demonstrates the full map of the conducted experiments
The Jotun Super Durable 2903® (JSD) polymer matrix showed higher actuation load values compared to Corro-Coat PE Series 7 (CC), due to its higher yield strength and density
