Co-crystalline (CC) polymer phases with small guest molecules can be obtained for many regular and stereoregular polymers. This lecture will be devoted to the very limited number of polymer CC phases that, by suitable guest removal procedures, can generate nanoporous-crystalline (NC) phases [1-4]. NC polymer phases, exhibiting density lower than for the corresponding amorphous phases, till now...

Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and syndiotactic polystyrene (sPS) are high-performance thermoplastics capable of forming co-crystalline (CC) phases with low-molecular-weight guest molecules. Upon guest removal, these materials transform into nanoporous crystalline (NC) structures that exhibit outstanding sorption properties toward gases and volatile organic compounds (VOCs)[1,2]....

Emerging contaminants in wastewater have become an important environmental issue, posing substantial risks to aquatic ecosystems and human health. Over the years, several remediation strategies have been explored; among them, adsorption has gained particular attention due to its low operational cost, straightforward implementation, scalability, and the possibility of regenerating and reusing...

Literature dealing with polyelectrolyte (PE) chains with atomic/molecular compensating ions in solution is vast [1–3]. Studies of PE chains in the presence of charged colloids or nanoparticles (NPs)[4] are less common. Interesting recent examples include PE complexes with gold and silica NPs[3], forming coacervates, or precipitates, with potential applications in phase separation processes,...

Waterborne latex films, obtained from the dispersion of latex particles, are of particular interest due to the non-content of volatile organic compounds (VOC), often mandatory under environmental legislation. To prepare efficient and solvent-free coatings with a low glass-transition temperature but higher mechanical strength, we have integrated hydrophilic layers (Acrylic acid/...

Ultra-low-crosslinked (ULC) PNIPAM microgels were complexed with tannic acid through supramolecular hydrogen-bond interactions. Rather than simply introducing additional crosslinks, tannic acid triggers a dramatic restructuring of the initially homogeneous and highly deformable microgels. The particles transform into a kinetically trapped core–shell architecture characterized by a depleted...

This contribution addresses the morphological properties of silica nanofillers embedded in styrene-butadiene elastomers and their structural rearrangement upon an applied deformation. Time-resolved ultra-small x-ray scattering (USAXS) patterns have been collected under the effect of a periodic deformation with variable dynamic amplitudes applied in-situ by means of a home-built DMA (Dynamic...

Supramolecular peptide assemblies (SPAs) are increasingly recognized as versatile building blocks for biomedical and nanotechnological applications due to their sequence-controlled self-assembly and tunable physicochemical properties [1]. However, establishing clear structure-property relationships that link peptide sequence to supramolecular organization remains challenging and requires an...

A thermoresponsive polymer, such as poly(isopropyl acrylamide) (PNIPAM), changes state when the temperature crosses its phase transition point. PNIPAM-based polymers exhibit broad hysteresis for the volume phase transition between the swollen and collapsed states. These polymers display atypical behaviors, such as bistability, remanence, information storage capabilities, and memory functions....

Polysaccharide–protein complexes represent attractive platforms for the encapsulation and delivery of hydrophobic bioactive compounds owing to their biocompatibility, biodegradability, and tunable physicochemical properties. In this study, complexes were formed via electrostatic co-assembly of bovine serum albumin (BSA) with oppositely charged κ- and λ-carrageenan. The effect of carrageenan...

Self-assembly is an effective strategy to prepare films at fluid interfaces. Conventionally, the structure and properties of self-assembled films are tuned through molecular interactions, chemical modifications, and varying pH. Here, we show that the preparation pathway, specifically the solvent evaporation rate during Langmuir film formation from homogeneous dissolved solution, provides an...

Abstract: Understanding the structural development and stereocomplex (SC) formation in polylactide (PLA)based block copolymer systems has garnered significant interest for tailoring material properties and expanding potential applications. In this study, we investigate the structural and morphological evolution of melt-quenched diblock copolymers, poly(isoprene‑b‑ʟ‑lactide) (PI-b-PLLA) and...
