Abstract Highly elastic silicone foams, especially those with tunable properties and multifunctionality, are of great interest in numerous fields. However, the liquid nature precursors complicated foaming process hinder realization its three‐dimensional (3D) printability. Herein, a series foams outstanding performance regards to elasticity, wetting sensing properties, tunability is generated by direct ink writing. Viscoelastic inks achieved from dispersion sodium chloride unique precursor...
An unprecedented four-dimensional (4D) printing process allowing high-performance and shape memory thermoset to be printed, for the first time, by fused deposition modeling (FDM) with isotropic properties has been achieved. Bisphenol A-based epoxy benzoxazine were formulated a low-temperature thermoplastic high-temperature resin, which is melt-extrudable can postcured into covalently cross-linked material. Carbon nanotube (CNT) was added in resin work as both mechanical enhancement filler...
Abstract Adhesives and sealants show fine rheology with good physical mechanical properties as viscous pastes, a possible starting point for developing direct ink writing (DIW) 3D printing ink. However, many commercial adhesives take days or weeks to cure fully. DIW 3D‐printed parts made directly from these are not designed scalable manufacturing process high‐volume production. Moreover, most of have volume shrinkage during cure. A systematic understanding formulation methods design...
Bisphenol A-based epoxies are much used in a wide range of composite and coating applications due to their excellent thermomechanical properties. However, 3D printability remains challenge with most reported materials suffering from high brittleness low toughness. Here, we have described especially modified epoxy resins that enable printing both fast slow curing rates. These exhibit greatly enhanced toughness, tunable properties, shape memory behavior. Two different systems, including...
Abstract Recently, photoinduced electron/energy transfer reversible addition–fragmentation chain (PET‐RAFT) polymerization has been developed and gaining wide acceptance. PET‐RAFT uses visible light to initiate the reaction is compatible with ambient conditions green solvents. It also maintains ability produce well‐defined polymers possesses high potential as an alternative conventional RAFT technique. This review aims summarize fundamentals of polymerization, highlight two most commonly...
Patterned surfaces with distinct regularity and structured arrangements have attracted great interest due to their extensive promising applications. Although colloidal patterning has conventionally been used create such surfaces, herein, we introduce a novel 3D patterned poly(N-isopropylacrylamide) (PNIPAM) surface, synthesized by using combination of templating surface-initiated photoinduced electron transfer-reversible addition–fragmentation chain transfer (SI-PET-RAFT) polymerization. In...
Abstract In this study, guest carriers, composed of magnetic‐directed hydrogel particles with near‐infrared (NIR)‐light‐triggered guest‐release properties, are prepared via the one‐pot method. The gel contain photostable NIR‐responsive polypyrrole nanoparticles temperature‐sensitive poly(N‐isopropyl acrylamide), combination which can induce accelerated release encapsulated drugs by 337% upon 5 minutes NIR light irradiation based on profile NRMG‐1 at 10–15 min. Additionally, magnetic iron...

The system formulated by combining chitosan modified catechol motifs, thermo‐responsive poly( N ‐isopropylacrylamide) terminated catechols, light‐absorbing polypyrrole nanoparticles (PpyNPs). effects of concentration, molar ratio Fe 3+ to units, the incorporation PpyNPs on mechanical property formed are investigated. responsive behaviors resulting composite NIR...
Abstract Photoinduced polymerization techniques have been used in preparing various polymeric materials as they share several advantages with thermally‐triggered processes using mild conditions, low catalyst concentrations, and easy‐to‐perform experimental conditions. By combining photoinduced eletrotransfer reversible addition–fragmentation chain transfer (RAFT) self‐condensing vinyl (SCVP), this work, a series of hyperbranched polymers is prepared flow reactor. Considered to be an...
A series of hybrid core–shell nanomaterials was prepared by solvent phase transfer methods with gold (Au) nanoparticles (NPs) as a core and star copolymers (h-PEI-b-PCL-Cbz) shell—consisting hyperbranched polyethyleneimine (h-PEI) different poly(ε-caprolactone) (PCL) chain lengths carbazole-contained terminating agent (Cbz). By varying the PCL length, these exhibited gradient energy properties, surface hydrophobicity, electropolymerizability, ionic probe transport diffusion properties. The...
Abstract Poly(ε‐caprolactone) (PCL)‐based nanomaterials, such as nanoparticles and liposomes, have exhibited great potential controlled release systems, but the difficulties in large‐scale fabrication limit their practical applications. Among various methods being developed to fabricate polymer nanosheets (PNSs) for different applications, Langmuir–Blodgett technique layer‐by‐layer assembly, are very effort consuming, only a few PNSs can be obtained. In this paper, poly(ε‐caprolactone)‐based...
Interfacial properties of polymeric materials are significantly influenced by their architectural structures and spatial features, while such a study topologically interesting macromolecules is rarely reported. In this work, we reported, for the first time, interfacial behavior catenated poly(l-lactide) (C-PLA) at air-water interface compared it with its linear analogue (L-PLA). The isotherms surface pressure-area per repeating unit showed significant behavioral differences between two...
