Cover Story Features Maitland’s Shape Polymer Foams

Duncan Maitland
The May 2012 issue of Journal of Polymer Science: Polymer Physics features Dr. Duncan Maitland’s shape memory polymer foams on the journal’s cover and publication of the article, “Ultra low density and highly crosslinked biocompatible shape memory polyurethane foams,” Singhal et al., May 2012. Maitland leads the Biomedical Device Laboratory in the department of biomedical engineering. Graduate students and research assistants Pooja Singhal and Jennifer N. Rodriguez were contributing authors.
The article details research on the development of highly chemically crosslinked, ultra low density polyurethane shape memory foams (SMPs) synthesized from symmetrical, low molecular weight and branched hydroxyl monomers. SMPs may be shaped into one form, changed into another shape and returned to the original shape on command, most commonly with heat or ultraviolet light (Texas A&M Engineer, 2010). These porous polymeric scaffolds constitute a fast emerging class of smart biomaterials with multiple potential applications, such as biomaterials for embolic devices in minimally invasive medical applications. A related article, “Opacification of Shape Memory Polymer Foam Designed for Treatment of Intracranial Aneurysms,” Rodriguez et al., was also recently published in the Annals of Biomedical Engineering.
