Biocompatible and bioactive scaffolds with multiscale porosity, shape memory effect and drug delivery performance are highly promising in bone tissue engineering applications within the approach of minimally invasive surgical implantation. In this study, we report an effective method to fabricate multiscale porous bioactive (MPB) scaffolds with shape memory effect by freeze drying of 3D printed high internal phase Pickering emulsion (Pickering HIPE) templates stabilized by hydrophobically modifi...

Abstract In this work, shape memory materials were developed for use as soft actuators. Shape memory polymers (SMPs) generally demonstrate good actuation on direct thermal heating. Here, we also demonstrate SMPs with good electric actuation via the incorporation of dibutyl adipate (DBA) plasticizers with shape memory polyurethane to form an SMP gel, which is a soft dielectric material. The effect of the plasticizer on the shape memory behavior under thermal stimulus was investigated. The SMP gel...

Abstract The preparation of polymeric materials with high performance and functional performance remains a focus of extensive research. In this paper, a good dispersion of regenerated chitosan (RCS) in the poly(vinyl alcohol) (PVA) and a physical cross-linking network of molecular chain entanglements and hydrogen bonding were realized by unique co-precipitation to prepare composites. Dynamic mechanical analysis and tensile tests demonstrated that RCS achieved a significant increase in the mechan...

Implanting a stent in the body through a minimally invasive operation and tracking its location in real-time is still a challenge. Herein, a near-infrared (NIR) light-triggered shape-memory polymer possessing a long-time fluorescence imaging function has been developed by cross-linking 6-arm poly(ethylene glycol)–poly(e-caprolactone) using a croconate dye YHD798 as the chemical crosslinker and NIR-absorption perssad. Due to the extraordinary photothermal conversion property of YHD798, the temper...

3D cell cultures are rapidly emerging as a promising tool to model various human physiologies and pathologies by closely recapitulating key characteristics and functions of in vivo microenvironment. While high-throughput 3D culture is readily available using multi-well plates, assessing the internal microstructure of 3D cell cultures still remains extremely slow because of the manual, laborious, and time-consuming histological procedures. Here, a 4D-printed transformable tube array (TTA) using a...

Abstract We present here a porous poly (L-lactide)/chitosan (PLLA/CS) composite scaffold with micro/nano-fiber hierarchical structure that was innovatively fabricated by combining 3D printing and thermally induced phase separation technology. Moreover, bioactive quercetin (Qu) was chosen to further functionalize the PLLA/CS scaffold with polydopamine (PDA) layer. The final results showed that the hydrophilicity and mechanical properties of the resulting PLLA/CS-D/Qu scaffold were obviously super...
