Journal ArticleDOI
3D-printed mechanochromic materials.
TL;DR: It was determined that the filament production and printing process did not degrade the spiropyran units or polymer chains and that the mechanical properties of the specimens prepared with the custom filament were in good agreement with those from commercial PCL filament.
Journal ArticleDOI
Controlled Depolymerization: Stimuli-Responsive Self-Immolative Polymers
TL;DR: This Perspective summarizes and discusses recent progress in this nascent area of research, including synthesis of different types of SIPs, design and evaluation of triggering moieties, depolymerization mechanisms and kinetics, applications of Sips, and the outlook and challenges facing the field.
Journal ArticleDOI
Mechanically triggered heterolytic unzipping of a low-ceiling-temperature polymer.
Charles E. Diesendruck,Gregory I. Peterson,Heather J. Kulik,Joshua A. Kaitz,Brendan D. Mar,Preston A. May,Scott R. White,Todd J. Martínez,Andrew J. Boydston,Jeffrey S. Moore +9 more
TL;DR: It is shown that a metastable polymer, end-capped poly(o-phthalaldehyde), undergoes mechanically initiated depolymerization to revert the material to monomers, suggesting the possibility of smart materials where aging or mechanical damage triggers depolymization, and orthogonal conditions regenerate the polymer when and where necessary.
Journal ArticleDOI
Biodegradable Shape Memory Polymers in Medicine.
TL;DR: This review provides an overview of biodegradable shape memory polymers that have been used in medical applications and their potential to facilitate the optimization and development of new medical applications.
Journal ArticleDOI
Production of Materials with Spatially-Controlled Cross-Link Density via Vat Photopolymerization
Gregory I. Peterson,Johanna J. Schwartz,Di Zhang,Benjamin Weiss,Mark A. Ganter,Duane W. Storti,Andrew J. Boydston +6 more
TL;DR: An efficient method to produce objects comprising spatially controlled and graded cross-link densities using vat photopolymerization additive manufacturing (AM) and changes in mechanical properties such as increased strain-to-break in inhomogeneous structures in comparison with homogeneous variants are measured.
