Full-IPN-structured thermosets are also suitable SMP systems. This was shown by Zhang et al. [79]. The IPN structure was composed of cross-linked PU (polylactide-glycolide-based (PLAGA) diol cross-linked by polyisocyanate) and cross-linked PEG dimethacrylate (cured by UV irradiation). The content of the latter was varied between 0 and 50 wt%. The IPNs were amorphous and exhibited a rather broad range (Tg between -23 and 63 C) that served for Both R( and data were reported over 93%. 

Tailored characterization methods for the SME were also developed for biomedical applications, such as for stents. A mechanical key characteristic for vascular stents is to withstand the compressive radial stresses over the lifetime of the application, i.e., maintain desirable thermomechanical characteristics with respect to recovery and deployment [63]. In a study on this topic, SME characterization methods were applied to a shape-memory stent from polymer networks, synthesized via photopolymerization of fert-butyl acrylate and PEG dimethacrylate [72]. The free recovery response of polymer stents at body temperature was studied as a function of Tg, crosslinking density, geometrical perforation, and deformation temperature.

Kwok et al. have reported on the development of ULS-sensitive barrier membranes able to give a pulsatile drug release. A co-polymer of 2-hydroxyl methacrylate (HEMA) and PEG dimethacrylate was loaded with particulate insulin and PEG, after which the surface of the polymer was coated with methylene chains. Upon exposure to ultrasound the methylene chains became disordered, permitting the insulin to diffuse out of the matrix [100,101].
