One-step wet electrospinning of graphene oxide-coated fibrous interfaces for flexible humidity sensing

Michele Gammino, Valentina Paolucci, Carlo Cantalini, Roberto Scaffaro

Abstract In this work, we use GO-assisted wet electrospinning/coagulation to investigate how polymer-matrix chemistry controls GO interfacial organization and humidity-responsive behavior in flexible fibrous coatings directly integrated on interdigitated electrode chips. The study focuses on the direct implementation of this approach for …

Bio-Based and Chemically Recyclable Vitrimers from Poly(lactide) and Isosorbide Diglycidyl Ether

Licia Gaeta, Michele Gammino, Camilla Noè, Maria Gentile et autres

Abstract Bio-based and chemically recyclable vitrimer networks were synthesized from star-shaped poly(lactic acid) (PLA) oligomers and isosorbide diglycidyl ether (DGEIs). Hydroxyl-terminated 4- and 6-arm PLA oligomers were functionalized with carboxylic acid end-groups to improve reactivity with DGEIs. Crosslinking in the presence of …

True-to-life microplastics obtained from PP pasta bags for efficient removal of pharmaceutical contaminants in aqueous systems

Marta Balsamo, Maria Chiara Mistretta, Roberto Scaffaro

The accumulation of microplastics (MPLs) in natural environments poses an increasingly serious threat to ecosystems and human health, either as microplastics themselves or as carriers of other contaminants. Moreover, the scarcity of information regarding the properties of real microplastics and their interactions …

Unexplored Green Solvent Systems for The Preparation of electrospun PLA and PCL functional Membranes: Overcoming Technological Lock-In

Emmanuel Fortunato Gulino, Roberto Scaffaro

Electrospinning enables the fabrication of nanofibrous membranes with high surface area, tunable porosity, and good mechanical performance. Nevertheless, the vast majority of studies still rely on potentially carcinogenic solvents, such as chloroform (CHF) and dichloromethane (DCM), particularly for polymers like polylactic acid …

Structure–Property Relationships Governing Rheological, Damping, and Thermal Behaviour of Immiscible Natural Rubber/Nitrile Rubber Blend Nanocomposites

Martin George Thomas, Sanitha Vasudevan, Hanna Joseph Maria, Ange Nzihou et autres

Polymer nanocomposites have been attracting significant interest over the last three decades. One of the most intriguing applications is related to the preparation of clay-filled nanocomposites based on rubber blend matrices. Although several studies already exist on the subject, there is limited …

Integrated approach to material selection: sustainability and mechanical characteristics

Alessandro Di Gesù, Caterina Antonia Dattilo, Lisa Bernacchi, Chiara Gastaldi et autres

Interest in sustainable materials is rapidly growing in both industry and academia. They are developed to reduce the use of non-renewable resources, limit climate-altering emissions, and promote recyclability or biodegradability. However, the availability of innovative materials is not enough: the key to …

Plant- and Animal-Derived Organic Waste as Fillers in Biodegradable Composites for Advanced Applications: A Comprehensive Overview

Roberto Scaffaro, Francesco Paolo La Mantia, Giada Lo Re, Vincenzo Titone et autres

Biodegradable polymeric composites reinforced with natural fillers represent one of the most promising routes toward low-impact, circular, and resource-efficient materials. In recent years, a growing number of studies have focused on the valorization of plant- and animal-derived organic waste, ranging from agricultural …
