In this work two types of biodegradable polysuccinimide-based, electrospun fibrous membranes are presented. One contains disulfide bonds exhibiting a shorter (3 days) in vivo biodegradation time, while the other one has alkyl crosslinks and longer time (more than 7 days). According to mechanical measurements, tensile strength is comparable those soft connective tissues visceral tissues. Further...

Abstract Nowadays, continuous development of soft-electronics and wearable devices opens to the needs stretchable flexible materials able interface with human body. In this scenario, biopolymers are particularly intriguing given their biocompatibility biodegradability. For application in specific field material requires several properties such as biological mechanical performance thermal stabil...

Control of surface wetting properties to produce strongly hydrophobic or hydrophilic effects is at the heart of many macro- and microfluidic applications. In this work, we have investigated coaxial electrospinning to produce core-sheath-structured nano/microfibers that combine different properties from individual core and sheath materials. Teflon AF is an amorphous fluoropolymer that is widely ...

Over the years, development of adaptable monitoring systems to be integrated into soldiers’ body gear, making them as comfortable and lightweight possible (avoiding use rigid electronics), has become essential. Electrospun microfibers are a great material for this application due their excellent properties, especially flexibility lightness. Their functionalization with graphene nanoplatelets (G...

Membrane filtration and affinity-based adsorption are the two most used strategies in separation technologies. Here, µm-thick multifunctional sustainable composite membranes of electrospun cellulose acetate (CA) infused with functionalized, anionic, cationic nanocrystals (CNCs) enhanced wettability, tensile strength, excellent retention capacities were designed. CNCs could uniformly impregnate ...
