The cover image by Juraij Kandiyil, Suni Vasudevan, and Sujith Athiyanathil shows the antifouling and selective methylene blue adsorption properties of polyurethane/montmorillonite-based electrospun composite membranes (PU/MMT). The optimized membrane showed water permeation with a high water flux of 4029 Lm⁻²hr⁻¹, significant oil rejection, a better flux recovery ratio, and a maximum MB adsorption capacity (q_m) of 112.35 mg/g. The developed, antifouling electrospun composite membrane opens a new avenue for the water treatment process. DOI: 10.1002/app.53464

Selective methylene blue adsorption and antifouling performance of polyurethane/montmorillonite-based electrospun composite membrane.

Dual physical network hydrogels were prepared rapidly at room temperature without the use of chemical cross-linking agents. The hydrogel is ultra-stretchable, tough, antifatigue, antifreezing and moisturing. Graphene was dispersed well in this hydrogel. The sensor with good adhesion and sensitivity ensures stable, reliable monitoring. Moreover, this sensor can monitor human size movement flexibly under extreme conditions.

Graphene-carbon black hybrid nanofiller for reinforcement of rubber

Lignin is a cost-effective renewable reinforcement material for composite fibers. This work investigates the possibility of employing bio-based high content lignin mixture by the regulation of ML composition for the reinforcement of high-performance poly (vinyl alcohol) fibers to achieve better sustainability with no sacrifice of fiber properties.

Reinforcing and plasticizing mechanism of reclaimed rubber.

The BaTiO₃@TiO₂ core-shell construction endows DE composites with an enlarged heterogeneous interface and enhanced interfacial polarization synchronously, which is also benefit to maintain the flexibility of DE materials. The buffer effect offered by TiO₂ shell is helpful to alleviate the local electric field concentration at the fillers-matrix interface in DE when being withstood the exponentially-growing electric field. Specifically, the maximum electro-actuated strain of 21% under a low electric field (40 V·μm⁻¹) is obtained from the DE composite filled with 4 wt% BaTiO₃@TiO₂, which is 290% higher than that of pristine PDMS (5.38% at 40 V·μm⁻¹).

A one-step water-based fabrication methodology to valorize hemp fibers into biocomposite materials was reported using pectin as a crosslinker. The compressive strength of these hemp fiber composites was pH-dependent and followed a V-shape trend, confirming the formation of ester bonds between pectin and lignin of hemp fibers via transesterification.

Polyurea (PUa) adhesives have unique properties due to their nanophase-separated morphology. Here, multiple experimental techniques (TEM and DSC) are used to elucidate the hard phase domain structure as a function of the formulation. A new micromechanical model is then proposed to describe linear viscoelasticity of the material and successfully validated based on DMA measurements.

A multiphase biomaterial ink combining type-I-collagen with nano-sized mesoporous bioactive glasses and nanohydroxyapatite was successfully designed to mimic the natural composition of bone. Based on rheological data and computational-fluid-dynamic models, the printing set-up was optimized to obtain scaffolds characterized by high printing fidelity and complex geometries, where the final mechanical stability was further enhanced by a chemical genipin crosslinking method.

Multi-ionic block copolymers with sulfonated amines and counter-ion substitution selectively allow the permeation of water, while inhibiting the transport of chemicals.

Synthesis pure mono, diglycidyl and glycidyl methacrylate of vanillyl alcohol thanks to industrializable process

A series of cycloolefin copolymers bearing bulky adamantane side group were prepared and characterized. Benefited from the significant steric hindrance of adamantane, both the unsaturated polymers and hydrogenated polymers showed outstanding thermal resistance, even at low NBDAE incorporations. Besides, the obtained COCs also exhibited improved mechanical performance and excellent transparency.

Modification mechanism of amphiphilic HMPSAs. Because of their nonpolar structure, hot-melt pressure-sensitive adhesive (HMPSAs) with SIS as the base material have significant difficulties in hydrophilic drug release. SIS-based amphiphilic medical HMPSAs SIS/AEO-9/PEG was successfully prepared in this study using AEO-9 and PEG of varying molecular weights. It can achieve the co-release of lipophilic and hydrophilic drugs, which has a wide range of applications.

The PA10T/AGF antistatic composites composed of PA10T, antistatic agent, 30 wt.% glass fiber possess excellent antistatic properties, thermal characteristics, balanced toughness, and notched impact strength.

Confocal-Raman spectra revealed that a mixed layer having a distance about 358 nm was formed at the interface of immiscible component polymers of IR and αOC by chemical reaction using peroxide crosslinking agent. Owing to the existence of the mixed layer at the interface, the adhesion strength was large and the tensile stress of the IR was enhanced.

Two polymerization route was evaluated, to obtain a immobilized palladium coordination compounds, but only one, the “one-step” synthetic route, by polymerization of MCM is suitable to obtain the immobilized coordination compound.
