DOI: 10.1002/app.44543

Abstract: Crosslinked self-healing polyurethanes based on Diels–Alder (DA) reaction were synthesized from a trifunctionalized isophorone diisocyanate (IPDI) and polypropyleneglycol prepolymer with furfuryl alcohol and a commercial bismaleimide. The DA reaction was followed by FTIR spectroscopy at… read more here.

DOI: 10.1002/marc.202401081

Abstract: Hexaarylbiimidazole (HABI) molecules have awakened a broad interest in photo‐processing, super‐resolution imaging, photoinduced self‐healing materials, and photomechanical hydrogels due to their excellent photosensitivity and photo‐induced cleavage properties. In this work, a novel photoswitchable branched polyurethanes… read more here.

DOI: 10.1021/acs.biomac.2c00662

Abstract: Polylactic acid (PLA) has received increased attention in the development of shape-memory polymers and biomedical materials owing to its excellent physical properties and good biocompatibility and biodegradability. However, the inherent brittleness and high shape-recovery temperature… read more here.

DOI: 10.15407/polymerj.46.02.119

Abstract: Polyurethane materials of different composition and structure were prepared using diisocyanates of different nature, native and functionalized vegetable oils. Hydroxylated derivatives of hemp oil, namely lineoyl diethanolamide (LDEA), whose structure was confirmed by IR spectroscopic… read more here.
