Summary: A porous semi-IPN hydrogel adsorbent with excellent adsorption properties towards Pb(II) was prepared using sodium alginate as main chains, sodium acrylate as monomers, and PVA as the semi-IPN component. The incorporation of PVA facilitated the formation of pores on the hydrogel surface, leading to high adsorption capacity and fast adsorption rate for Pb(II). Additionally, the presence of PVA improved the gel strength and reusability of the hydrogel.

Summary: In this study, a simple and efficient method was developed to functionalize the surface of multiwalled carbon nanotubes (MWCNT) with precise functional polymer chains, which were covalently grafted on the surface of the MWCNT. These polymer-grafted MWCNTs were then used as nanofillers in developing proton conducting membranes with enhanced properties. The novelty of this work lies in successfully grafting a same N-heterocyclic block copolymer structure covalently on the surface of the MWCNT.

Summary: Traditional sunscreens can penetrate the skin, raising safety concerns. To address this, a cellulose nanocrystal/polydopamine/poly(vinyl alcohol) (CNC/PDA/PVA) hydrogel was developed with biocompatibility, UV-shielding, and antioxidant properties. The hydrogel showed a compression strength of 5.0 MPa and remained stable after UV exposure. It demonstrated excellent biocompatibility, strong antioxidant capacity, and the ability to block 99.0% of UV light, protecting against UV-induced tissue injury. These findings highlight the potential of the CNC/PDA/PVA hydrogel as a next-generation UV absorber and antioxidant material.

Summary: A bio-derived char-forming strategy using a vinyl-modified tannic acid (VTA) for surface fireproofing was developed in this work. The novel UV-curing coating, which integrated epoxy acrylate resin, VTA, and TGMA, demonstrated superior fireproofing effect on PET sheets with a UL-94 V-0 rating. The presence of VTA in the coating increased the pyrolysis char yield and inhibited heat transfer, leading to better rigidity, abrasion resistance, and water fastness.

Summary: In this study, the capability of Terahertz spectroscopy for determining the thermal properties of phase change materials (PCM) in an acrylated polyurethane coating was investigated. Spherical shaped mesoporous silica materials (MPSs) were used as a template for stearic acid (SA) and SA was impregnated into MPSs to investigate its PCM properties. The thermal properties of the resin were determined using both conventional Differential Scanning Calorimetry (DSC) and Terahertz Time Domain Spectroscopy (THz-TDS), showing that THz Spectroscopy is a strong technique for characterizing phase changing materials.
