Design/methodology/approach In this work, a novel polymer microsphere, PS-DVB-P(AA-Na)-SPABA, was synthesized by grafting poly(sodium acrylate) (P[AA-Na]) polymer brushes onto polystyrene-divinylbenzene (PS-DVB) via surface-initiated atom transfer radical polymerization, followed by modification with p-aminobenzoic acid (SPABA). The chemical structure of PS-DVB-P(AA-Na)-SPABA was confirmed by multiple methods, such as Fourier transform infrared and X-ray photoelectron spectroscopy analysis. Findings The adsorption process showed a good fit with the pseudo-second-order kinetic and Freundlich isotherm models. The thermodynamic parameters of the berberine adsorption process revealed that adsorption was spontaneous and endothermic. The resulting polymers were promising for the adsorption of berberine, with a maximum capacity of 221.22 mg/g. Electrostatic interaction, hydrogen bond interaction and p-p interaction are likely to govern the adsorption process of berberine. Furthermore, PS-DVB-P(AA-Na)-SPABA retained a favorable adsorption performance for berberine after five cycles, indicating that the material possesses regenerability and reusability.

Design/methodology/approach A hierarchical assembly approach was used to fabricate Mn²+-(Fe3O4/manganese-substituted hydroxyapatite (Mn-HA))@ß-CD nanoparticles (NPs) as the composite carrier. The design incorporated Fe3O4 NPs as the magnetic core, while Mn²+ ions coordinated with ß-cyclodextrin (ß-CD) and Mn-HA complexes to form a structurally reinforced core-shell coating layer. Systematic investigations were conducted to optimize critical parameters, including immobilization methodologies, carrier microenvironment characteristics and organic linker arm dimensions. The effects of these parameters on catalytic efficiency, storage stability and operational reusability were comprehensively evaluated. Findings The optimized Mn²+-(Fe3O4/Mn-HA)@ß-CD-g-KH560-PGA nanoparticles demonstrated exceptional biocatalytic performance, achieving an enzyme activity (EA) of 31,414 U/g with an EA recovery rate of 93.8% and enzyme loading capacity of 138 mg/g. The immobilized PGA exhibited remarkable operational stability, maintaining 70.0% of its initial activity after 12 consecutive catalytic cycles, with a recovery ratio of 89.5%. These superior properties were attributed to the Mn²+-rich composition, polyhydroxy functionality and optimized linker arm architecture of the composite carrier.

The design and preparation of adsorbent is the core of an adsorption system. From the viewpoint of sustainable development, adsorbents with fewer preparation steps, simpler preparation process, less use of organic solvents are urgently needed and favorable for the adsorption process. In addition, adsorption efficiency is another important factor to be considered. Design/methodology/approach Chitosan metal complex (CTS-Cu) was prepared via a green and facile method with distilled water, and then it was characterized by a series of techniques. Applying the complex, this study was sought to detect the efficacy of removing organic dyes from aqueous solution. Findings The methyl orange (MO) adsorption was significantly affected by adsorption temperature and ionic strength. The adsorption capacity of CTS-Cu for MO was as high as 344.10 mg/g, while that of chitosan (CTS) was 34.14 mg/g at 45°C, indicating the superior advantage of modification and relatively higher affinity of the former adsorbent. It was interesting to find that CTS-Cu exhibited certain adsorption selectivity of MO to methylene blue (MB). However, CTS had certain adsorption selectivity of MB to MO. Research limitations/implications The chitosan–metal complexes with other metals have been prepared. The adsorption behaviors for organic dyes of these materials need further and future investigation. Practical implications CTS-Cu was prepared with distilled water as solvent under room temperature. The costs of CTS and CTS-Cu were relatively low. CTS-Cu could effectively enrich anionic dyes like MO from aqueous solution. Originality/value The preparation process of CTS-Cu was simple and relatively green.

Monobutyl itaconate (MBI), an unsaturated carboxylic acid, its application as functional monomer in emulsion polymerization at low concentration could effectively improve the thermal stability of emulsion and the adhesion of various matrixes, and allow the introduction of reactive groups on the surface of particles after modification. The purpose of this paper is that MBI is used to modify the latex. MBI can produce a cross-linked network structure with acrylate, which can be formed by the hydrolysis in this system. The water molecules cannot permeate into the cross-linked network when the amount of MBI is moderate. Design/methodology/approach The MBI modified cationic acrylate latex was successfully prepared via the semi-continuous emulsion polymerization of butyl acrylate (BA), methyl methacrylate (MMA) and MBI in water phase, which were initiated with water soluble azo initiator and emulsified with the mixed surfactants of dodecyl amine ethoxylates quaternary (DAEQ) and alkyl polyglucosides (APG). The films of the resultant latex were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry (DSC) and contact angle (CA) determinator, respectively. Findings The conditions of preparing the modified latexes were optimized and obtained as follows: the amount of emulsifiers and the initiator are 6.0% (Wt.%) and 0.6% (Wt.%), respectively; the mass ratio of DAEQ to APG is 3:1; the amount of MBI is 4.0% (Wt.%). In this case, the conversion percentage is high and the polymerization stability is good. In comparison with the conventional cationic acrylate latex, the water resistance of modified latex films is improved. Originality/value Preparation of the MBI modified cationic acrylate latex is seldom reported. In this study, The MBI modified cationic acrylate latex was successfully prepared via the semi-continuous emulsion polymerization of BA, MMA and MBI in water phase, which were initiated with water soluble azo initiator and emulsified with the mixed surfactants of DAEQ and APG.","PeriodicalId":20214,"journal":{"name":"Pigment & Resin Technology","volume":"55 3","pages":"370-374"},"PeriodicalIF":0.0,"publicationDate":"2025-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147902691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design/methodology/approach The study systematically examined the influence of various factors on the degradation of RR218, including initial pH, PMS concentration, CuO@LSC catalyst concentration, reaction temperature and the type and concentration of ionic species. Furthermore, the degradation mechanism of RR218 via free radical pathways was thoroughly investigated. Findings Under the conditions of 0.125 g/L CuO@LSC catalyst, 0.25 g/L PMS, at 25°C, and an initial pH of 9, a reaction time of 30 min achieved a degradation of up to 98.20%. Despite a 4.18-fold slowdown in dye degradation with sodium chloride (NaCl), the final degradation efficiency still reached 98%. In contrast, the addition of sodium sulfate (Na2SO4) inhibited dye degradation, resulting in a degradation of less than 90%. Furthermore, the experimental results confirmed that dye degradation occurs due to the combined action of sulfate radicals (SO4•−), singlet oxygen (1O2) and hydroxyl radicals (·OH).

Polybutylene adipate terephthalate (PBAT) has excellent biodegradability, which has been widely used in various fields, such as biomedical supplies, plastic packaging materials, industrial composting and daily sanitary consumables.

In this study, the glass fiber (GF)/PBAT composites were prepared, and the effect of GF and the modifiers on the structure, mechanical properties and shape memory properties of the composites were investigated.
