Abstract The studies of structure‐property relationship in ionic liquid monomers (ILMs) and their corresponding poly(ionic liquid)s (PILs) are required to gain deeper understanding tunable physical, chemical, mechanical properties. In this work, a series 2‐(alkyldimethylammonium)ethyl methacrylate bromide ([R‐DMAEMA][Br]) ILMs synthesized followed by free‐radical polymerization obtain the analogous PILs with alkyl chains varying lengths. introduction long chain induces crystallinity these ILMs, whose melting temperature, enthalpy fusion, increase increasing length alkyl‐chain. Exchange Br − bulkier NTf 2 leads substantial change crystalline behavior ILMs. bromide‐based show detectable semicrystallinity due presence crystallizable pendent chains. Both bromide‐ ‐based strongly birefringent crystals various morphologies but, give fibrillar morphology very weak birefringence. No such fibrils observed for PILs.

ABSTRACT This study investigates the thermal, mechanical, and photothermal‐driven shape memory properties of 3D‐printed polydopamine (PDA) polylactic acid (PLA) blends in context 4D printing. Homemade PDA particles were incorporated into PLA matrix via melt blending, printing was performed using fused deposition modeling (FDM) to fabricate composite parts with superior mechanical properties. These enable remote light‐driven actuation, achieving up 70% recovery within 300 s. Increased laser power density three times original, time shortened from 420 s 180 Furthermore, incorporation improved material's surface wettability. Specifically, water contact angle pure 83.2° at 20 s, whereas addition 3 wt% reduced it 51.8°. results suggest potential application material as a scaffold for bone tissue engineering.

ABSTRACT In this study, blends of thermally‐activated shape memory polymers were created by merging ester‐based thermoplastic polyurethane (TPU) as the permanent elastomer phase with methacrylate‐based poly(butyl methacrylate‐co‐isobutyl methacrylate) (BM) serving switching phase. The using a melt blending technique, and their morphology, thermal characteristics, mechanical properties, capabilities examined. Scanning electron microscopy (SEM) revealed phase‐separated morphologies, transition from small spheres to co‐continuous phases BM content increased. A structure was achieved for TPU/BM ratios 60/40 50/50. Dynamic analysis (DMA) differential scanning calorimetry (DSC) that incorporating modified glass melting temperatures TPU phases, leading notable changes in properties compatibility material. Fourier transform infrared (FTIR) indicated new interactions between hard segments polymer, influencing blend's separation. thermogravimetric analyses, onset degradation found lie values two polymers, while maximum temperature increased presence TPU. Shape performance assessed thermomechanical (TMA), results showing improved fixing recovery 50TPU‐50BM blend exhibited highest (98.91%) (98.68%) ratios, demonstrating excellent thermo‐responsive behavior. This work highlights potential smart applications.
