ABSTRACT
As presented in Chapter 3, moisture exerts a signižcant in˜uence on the glass transition temperature (Tg) of a polyurethane shape memory polymer (SMP) from SMP Technologies, Japan. After blending with carbon nano powders, electrically conductive SMP composites were produced and characterized as detailed Chapter 4. They can be directly heated for recovery by Joule heating (passing an electrical current) so that a wider range of applications can be realized. However, the effects of moisture on the electrically conductive SMP composites are still not known. A good understanding of this issue is signižcant in engineering applications. Therefore, this chapter aims to address this issue by studying the samples discussed in Chapter 4. Again, CBX denotes the polyurethane SMP (MM5520) composites with X% volume fraction of carbon powders. Hence, CB0 is the pure SMP without carbon powder.
