Poly(ɛ-caprolactone) (PCL) (PCL CAPA 6500, Mn 50 000 g mol⁻¹, 0.5 wt%—caprolactone monomer) was supplied by Perstorp® Sweden.
Chloroform (CHCl₃) (99.6% purity) and N,N-dimethylformamide (DMF) (99.5% purity) from Sigma-Aldrich were used as solvents.
Two types of nanoparticles were used as reinforcement: magnesium oxide nanoparticles (MgO, purity: 99.9%, APS: 20 nm) and magnesium hydroxide nanoparticles (Mg(OH)₂, purity: 99%, APS:10 nm), which were supplied by Nanoshel.
The electrospun nanofibers were prepared using an Electrospinner Y-flow 2.2.D-XXX (Nanotechnology Solutions) in vertical standard configuration coupled to coaxial concentric needles, following the protocol that we used in our previous work [29 (link)].

ε-Caprolactone, pentaerythritol, tin octanoate (Sn(Oct)₂), toluene (anhydrous, purity 99.7%), dichloromethane (DCM), chloroform, methanol and methylene diphenyl diisocyanate (MDI) were purchased from Sigma Aldrich^® (Milan, Italy). Prior to use, ε-Caprolactone was purified by vacuum distillation over CaH₂. All other reagents were of analytical grade and were used without purification. Reduced graphite oxide (rGO) with a surface area of 196 m²/g (BET), an oxygen content of 2.0% (XPS), and a Raman value of I_D/I_G 1.35 at 514 nm, were provided by Avanzare Innovación Tecnólogica (Navarrete (La Rioja), Spain). The preparation method [26 (link)] and full characterization [27 (link)] was previously reported elsewhere. Commercial grade PCL CAPA^® 6500 (Mw = 50,000 g/mol) was purchased from Perstorp (Malmö, Sweden).

Poly(ε-caprolactone) (PCL) (PCL CAPA 6500, Mn = 50,000 g/mol, 0.5 wt% ε-caprolactone monomer) was kindly donated by Perstorp (Malmö, Sweden).
Chitosan (degree of deacetylation > 75%) [17 (link)], microcrystalline cellulose, as well as commercial hydroxyapatite nanofillers (HA, the particle size of about 30 nm), were purchased from Sigma-Aldrich (Madrid, Spain). Silver nanoparticles, Ag, (P203, Cima NanoTech, Caesarea, Israel) were previously purified by a thermal treatment, obtaining a specific surface area of 4.9 m²/g and particle size distribution from 20 to 70 nm [50 (link)]. Graphene nanoplatelets were supplied by Cheap Tubes Inc., Grafton, VT, USA (Grade 2) [51 (link)]. As indicated, they had a surface area of about 100 m²/g and an average thickness of a bit less than 10 nm. They were used as supplied by the manufacturer without any functionalization process. Fumed silica dioxide nanopowder, SiO₂ (primary particle average size: 7–14 nm), was purchased from Interchim Innovations (Montluçon, France) [39 (link)]. Chloroform (99.6% purity) (CF) and dimethylformamide (DMF) (99.5% purity) were supplied by Sigma Aldrich (Madrid, Spain).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
