“…This was because the higher polymer content implied relatively dense and rigid networks, which was helpful to resist higher stress. Furthermore, the mechanical strength of hydrogels is also influenced by pore size [40]. As shown in Fig.…”

“…The peak at 1046 cm −1 could be contributed to the typical stretching vibration of C OH bonds in salecan. In addition, OH stretching vibrations of salecan might be overlapped by the strong absorption of NH stretching vibrations of PNIPAm and BAAm at 3291 cm −1 [40]. The two small peaks at 1386 and 1366 cm −1 hinted the stretching in the isopropyl group of PNIPAm.…”

“…With a high density of hydroxyl groups, the large molecular weighted (2 × 10 6 Da) salecan could be further modified for multifarious applications. Recently, salecan was successfully used in the preparation of novel hydrogels with certain polymers by our group [39,40]. It was indicated that the hydrophilic salecan could be a suitable candidate for biomedical applications.…”

Novel semi‐interpenetrating network structural phase change composites with high phase change enthalpy

et al. 2017

High phase change enthalpy, controllable temperature, and stable shape can expand the application of phase change materials (PCMs) in energy storage. In this study, a series of novel form-stable PCMs with high phase change enthalpy (169-195 J/g) and controllable temperature (45.3-61.48C) were prepared. The PCMs exhibited a semi-interpenetrating polymer network (semi-IPN) structure resulting from the combination of polyethylene glycol (PEG) and a threedimensional (3-D) network gel. The gel itself featured an inherent phase change characteristic and a 3-D network structure. Thus, it improved the phase transition enthalpy of the materials and facilitated the formation of a semi-IPN that endowed the materials with excellent form-stable properties. In addition, the latent heat of the composites (169-195 J/g) is much higher than most of the previously reported composites using PEG as phase change component (68-132 J/g).

The synthesis of a novel interpenetrating chitosan network post‐modified with spiropyran (SP) derivatives has been used to develop photochromic hydrogels. We have synthesized succinyl chitosan polymers containing a considerable number of both amines and carboxylic groups. Their intra/inter molecular amide coupling reactions and postmodification with SP derivatives resulted in the photochromic hydrogels functionalized with chitosan‐based interpenetrating polymer network structures. In this hydrogel system, SPs undergo reversible photoresponsive structural switching between a ring‐closed colorless SP form and a ring‐opened purple merocyanine form under specific light‐irradiation conditions. Notably, the photo‐mediated wettabilities and color intensities of the hydrogels increase by the increment in the molecular weight of SP‐functionalized chitosans. © 2017 Wiley Periodicals, Inc. J.
