A Sequential One‐Pot Block Copolymer Synthesis: Toward Mesoporous Carbon Materials for Selective CO2 Adsorption

open access: yesMacromolecular Rapid Communications, EarlyView.
A sequential one‐pot photo‐iniferter RAFT method greatly simplifies the synthesis of PAN‐based block copolymers, offering quick access to hierarchically porous, N‐doped carbon membranes. This scalable and reliable process allows for easy fabrication of functional materials important for carbon capture applications.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

open access: yesPolymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

open access: yesPolymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Computational design of poly(p‐phenylene vinylene)‐based gas sensors: tunable reactivity and selectivity via side‐group functionalization

open access: yesPolymer International, EarlyView.
Side‐group functionalization enhances the reactivity and optoelectronic properties of poly(p‐phenylene vinylene) (PPV) derivatives for chemical sensing. PPV‐CN and PPV‐NO2 display strong interactions and pronounced responses, providing molecular‐level insights for designing high‐performance polymer‐based sensors.

Influence of sulfonation degree and deposition technique on the electrical and morphological properties of sulfonated polystyrene thin films

open access: yesPolymer International, EarlyView.
Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.

Porous Modified Calcium Carbonate as an Efficient Carrier for Gallic and Ascorbic Acids in Humidity‐Activated Oxygen Scavenging Systems

open access: yesPackaging Technology and Science, EarlyView.
Porous modified calcium carbonate (MCC) is presented as an efficient carrier for humidity‐activated oxygen scavengers based on gallic acid and ascorbic acid. The porous MCC structure preserves high accessibility of the active compounds, enabling effective oxygen scavenging under high relative humidity, with performance governed by loading level ...

Moisture Change Model for Active Package of Dry Dosage Forms Under Consumer Use Condition

open access: yesPackaging Technology and Science, EarlyView.
A simple mathematical model was developed to estimate moisture contents of dry dosage product packaged with desiccant during in‐use condition, where each dosage is taken out periodically. The model utilizes sequential summation of individual steps of package layer's moisture transmission and internal equilibration among the headspace, product and ...
