    To produce facile remote-stimuli thermosensitive nanocomposite hydrogel, a novel near-infrared (NIR) laser switched CuS/clay/poly(OEGMA-co-MEO2MA) hydrogel is fabricated. The temperature change and dimensional variation of hydrogel are related to the NIR intensity, CuS content, and crosslinking density. The hydrogel can be utilized as smart liquid valve, which can be remotely controlled by NIR switch on/off successfully.

  2. Epoxy-Based Azopolymers with Enhanced Photoresponsive Properties Obtained by Cationic Homopolymerization

    Romina P. Ollier, Marianela Victorel, Gustavo F. Arenas, Patricia A. Oyanguren, María J. Galante and Walter F. Schroeder

    A new type of azo-modified epoxy network has been prepared by the way of cationic homopolymerization with boron trifluoride monoethylamine (BF3·MEA) complex as initiator. The resulting networks are promising materials for optical storage applications.

  3. Amorphous Electrically Actuating Submicron Fiber Waveguides

    The properties of novel electrically actuating and waveguiding amorphous polymer submicron fibers are investigated in detail. These fibers guide light at subwavelength diameters with a group velocity greater than 0.71c0. The fiber mat also demonstrates electrical actuation with a high apparent piezoelectric constant of ≈29 000 × 10−12 m V−1. Extremely small and functional waveguides can be used to produce novel opto-electromechanical devices.

  4. Ionically Crosslinked Thermoresponsive Chitosan Hydrogels formed In Situ: A Conceptual Basis for Deeper Understanding

    This study uncovers the role of urea and isobutanol as chemical modifiers by comparing three classes of hydrogels. An increased or a decreased pH affects gelation, where the best conditions for gelation would be achievable in the case of neutral medium. Either a rise or a fall in pH value upsets the balance between electrostatic interactions and crosslinking, the driving forces behind gelation.

  5. Biodegradable Inorganic–Organic POSS–PEG Hybrid Hydrogels as Scaffolds for Tissue Engineering

    Jingjing Yu, Zongtao Liu, Jinrui Shen, Cuifen Lu, Xingjian Hu, Nianguo Dong, Guichun Yang, Zuxing Chen and Junqi Nie

    A series of inorganic–organic polyhedral oligomeric silsequioxanes–poly(ethylene glycol) (POSS–PEG) hybrid hydrogels are prepared in water by covalently grafting POSS into PEG and further cross-linked by matrix metalloproteinase degradable peptide via Michael-type addition. All POSS–PEG hybrid hydrogels have a porous structure, high mechanical properties and hydrophilic ability, good biodegradability and biocompatibility.
