Novel brush coatings were fabricated with glass surface-grafted chains copolymerized using surface-initiated atom transfer radical polymerization (SI-ATRP) from 2-(2-methoxyethoxy)ethyl methacrylate (OEGMA188) and acrylamide (AAm), taken in different proportions. P(OEGMA188-co-AAm) brushes AAm mole fraction >44% (determined XPS TOF-SIMS spectroscopy) nearly constant the depth copolymer composition (TOF-SIMS profiling) exhibit unusual temperature-induced transformations: The contact angle of...
Abstract Polymer nanocomposites, such as polyethylene terephthalate (PET)‐clay systems, leverage intricate interactions between components to fine‐tune their thermal, mechanical, and rheological properties. In our study, we functionalized montmorillonite clay nanofillers (CloisiteNa + ) fabricate recycled PET‐clay nanocomposites. The underwent a three‐step functionalization process, involving the treatment with (3‐Aminopropyl)triethoxysilane (APTES), grafting of initiating coatings...
Poly(methacrylic acid) (PMAA) is a well-known pH-responsive polymer with underexplored temperature-responsive properties. This study investigated the properties of PMAA grafted brush coatings, synthesized via SI-ATRP polymerization sodium...
The fabrication of multifunctional, thermoresponsive platforms for regenerative medicine based on polymers that can be easily functionalized is one the most important challenges in modern biomaterials science. In this study, we utilized atom transfer radical polymerization (ATRP) to produce two series novel smart copolymer brush coatings. These coatings were copolymerizing 2-hydroxyethyl methacrylate (HEMA) with either oligo(ethylene glycol) methyl ether (OEGMA) or N-isopropylacrylamide...
Poly( n-butyl methacrylate) (PBMA) or poly( acrylate) (PBA)-grafted brush coatings attached to glass were successfully prepared using atom-transfer radical polymerization "from the surface". The thicknesses and composition of PBMA PBA examined ellipsometry time-of-flight secondary ion mass spectrometry (ToF-SIMS), respectively. For PBMA, glass-transition temperature constitutes a range close physiological limit, which is in contrast PBA, where around -55 °C. Atomic force microscopy studies...
Non-cytotoxic, temperature-responsive and antibacterial poly(di(ethylene glycol)methyl ether methacrylate) - POEGMA188 based nanocomposite coatings attached to a glass surface were successfully prepared using ATRP polymerization. The thickness, morphology wettability of the resulting analyzed ellipsometry, AFM contact angle measurements, respectively. strong impact thicknesses grafted brush content AgNPs on temperature-induced changes was demonstrated. In addition temperature-dependent...
This study explores the biodegradation of polyhydroxybutyrate (PHB), polylactide (PLA), and their blends by 11 bacterial species (including Antarctic strains) 6 fungal species. Aeration significantly enhanced PHB degradation mold fungi (Aspergillus oryzae, Penicillium chrysogenum) bacteria (Paenibacillus tundrae, Bacillus mycoides), while Aspergillus awamori was most effective under non-aerated conditions. For PLA, peaked aeration with chrysogenum subtilis. PHB/PLA degraded slower overall,...
Poly(4-vinylpyridine)-grafted brushes demonstrate a thermal response of their wettability (stronger than that for spin-coated films), surface morphology, and protein adsorption.
In the present work, we have successfully prepared and characterized novel nanocomposite material exhibiting temperature-dependent surface wettability changes, based on grafted brush coatings of non-fouling poly(di(ethylene glycol)methyl ether methacrylate) (POEGMA) with embedded CaCO3 nanoparticles. Grafted polymer brushes attached to glass were in a three-step process using atom transfer radical polymerization (ATRP). Subsequently, uniform nanoparticles (NPs) POEGMA-grafted synthesized...
