چکیده
In this work, electro-responsive shape-memory actuators were developed by incorporating a conductive heater in dual-curing thiol-acrylate-epoxy polymer (SMP). A heater, consisting of an electrically silver-ink track printed on Kapton® substrate, was assembled to the SMP, taking advantage processing. The effect (SME) activated heat dissipated Joule track. Boron nitride agglomerates dispersed layers increase thermal conductivity and achieve faster shape-recovery. thermoelectric control unit shape recovery provide different activation strategies. SME investigated compared traditional based external heating source given dynamic mechanical analyzer (DMA) apparatus. Electro-responsive found extremely than conventional SMPs heating. fastest obtained 15% boron actuator, which recovered 100% original only 8 s. controlling device provided optimal speed pulse width modulation current under application low voltage (5 V).

متن کاملLinear topology in amorphous metal oxide electrochromic networks obtained via low-temperature solution processing.
Amorphous transition metal oxides are recognized as leading candidates for electrochromic window coatings that can dynamically modulate solar irradiation and improve building energy efficiency. However, their thin films are normally prepared by energy-intensive sputtering techniques or high-temperature solution methods, which increase manufacturing cost and complexity. Here, we report on a room...
متن کاملDramatic Improvement of the Mechanical Strength of Silane-Modified Hydroxyapatite–Gelatin Composites via Processing with Cosolvent
Bone tissue engineering (BTE) requires a sturdy biomaterial for scaffolds for restoration of large bone defects. Ideally, the scaffold should have a mechanical strength comparable to the natural bone in the implanted site. We show that adding cosolvent during the processing of our previously developed composite of hydroxyapatite-gelatin with a silane cross-linker can significantly affect its me...
