Summary: Discoloration of wood coatings due to fungal growth affects their aesthetic properties. Incorporating silver nanoparticles (AgNPs) in acrylic latexes as antifungal agents can control fungal growth. The dispersion of AgNPs within the latex particles and dry film is influenced by the type of initiator used in miniemulsion polymerization. Despite a smaller amount and less uniform dispersion, acrylic latexes prepared with potassium persulfate (KPS) as the initiator show higher antifungal efficiency against black-stain fungi (Aureobasidium pullulans) compared to those prepared with azobisisobutyronitrile (AIBN).

Summary: Alkali soluble resin stabilized latexes are commonly used in waterborne coatings, but little is known about how the high T-g nature of the ASR influences film formation and how to design systems to minimize MFFT. This study synthesized ASRs and ASR stabilized latexes to explore their effects on drying and deformation processes during film formation. The results showed that ASR absorption of water increases the effective volume fraction of polymer during drying, and the wet T-g of ASR and the emulsion polymer both affect MFFT in ASR/latex blends.

Summary: This study investigates the influence of alkali soluble resins (ASRs) on the mechanical properties of latex films. It is found that the composition of the copolymer phase has little effect on the Young's modulus, while the high Tg ASR phase plays a key role. Increasing the Tg of the copolymer phase leads to higher elongation break and tougher materials. Polar additives in coatings formulations selectively plasticize the polar ASR phase, resulting in a significant decrease in mechanical performance.

Summary: Polycarboxylic ethers or polycarboxylate (PCEs) are commonly used superplasticizers in construction, but their microstructure-property relationship is not fully understood. A theoretical model has been proposed to explain the effect of PCE's microstructure-conformation on its adsorption onto cement particles and cement hydration time. Experimental investigation shows that PCEs with different side chain lengths have different dispersing mechanisms. The theoretical model's prediction is mostly accurate, except for PCEs with the shortest side chains.

Summary: The thermally initiated thiol-ene emulsion polymerization of DAP diene and EDDT dithiol monomers was studied in batch and semibatch processes. The stability of the latexes was limited in both processes, leading to aggregation phenomena. Changing the diene monomer to DATP resulted in smaller particles and narrower distribution without aggregation. Partial substitution of the dithiol by a more water-insoluble trithiol affected nucleation, yielding smaller particles. The synthesized polythioether polymers showed low glass transition temperatures and crystalline films.

Summary: In this study, Methacrylic acid-co-poly(ethylene glycol methacrylate) (MAA-co-PEGMA) copolymers with uniform composition but different charge-density or side chain lengths were synthesized by free-radical copolymerization. The effect of these copolymers on the hydration kinetics of Ordinary Portland Cement (OPC) was analyzed. It was found that increasing the PCE concentration led to a delay in hydration. Moreover, the delay was longer with higher MAA/PEGMA ratios or shorter side chain lengths of PEGMA. The hydration delay was proportional to the carboxylate dosage and all PCEs fit in a master curve, indicating a correlation between the microstructure of the PCEs and the hydration delay of commercial OPC.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
