“…In addition to being a PCM, PEG is also used as a compatibilizer to improve the compatibility between fillers and resin substrates, because PEG can coat the surface of fillers well 42–44 . However, pure PEG or PEG/filler coatings are difficult to directly be applied in practical production due to the excessive hydrophilicity and easy detachment 45,46 . WER was added to the PEG/filler composite system in this work to improve the adhesion and other properties.…”

Polyethylene glycol (PEG) is a widely available and environmentally friendly phase change material known for its high energy storage capacity. However, its application in various industries is limited due to slow heat absorption and release, poor mechanical properties, and inadequate weather resistance. PEG was blended with waterborne epoxy resin (WER) to improve its mechanical properties and weather resistance. Furthermore, graphene nanoplatelets (GNPs) and boron nitride (BN) were incorporated into the WER/PEG resin substrate to prepare WER/PEG/BN@GNP coatings, resulting in enhanced thermal conductivity. When the GNP content was 0.5 wt%, the WER/PEG/BN@GNP coatings performed excellent anti‐corrosion. Otherwise, the leakage of PEG under heat‐cool cycling was addressed by the preparation of WER/PEG/BN@GNP coatings, as well as the low rates of heat absorption and release. In this work, the preparation method successfully combines the phase‐change characteristics of PEG, the outstanding mechanical properties of WER, and the high thermal conductivity of BN and GNP. The WER/PEG/BN@GNP coatings present significant potential for practical applications.Highlights A new coating is prepared by incorporation of BN/GNP into PEG/WER matrix. The prepared coating performs phase change and good heat conduction efficiency. The phase‐transition leakage of PEG is resolved by the combination with WER. The synergy of BN and GNP fillers can enhance thermal conductivity effectively. The prepared coating exhibits insulation and anti‐corrosion at low GNP content.

“…Granule based FDM 3D-printers are very expensive and usually constitute the equipment of specialized laboratories. The great advantage of the using granular feedstock is the possibility to mix different materials to create composite scaffolds [ 12 , 13 ]. Most of the work carried out with PCL and 3D-printing requires the use of granulate/powder and is associated with time-consuming preparation of the material [ 14 ].…”

In this work, composite filaments in the form of sticks and 3D-printed scaffolds were investigated as a future component of an osteochondral implant. The first part of the work focused on the development of a filament modified with bioglass (BG) and Zn-doped BG obtained by injection molding. The main outcome was the manufacture of bioactive, strong, and flexible filament sticks of the required length, diameter, and properties. Then, sticks were used for scaffold production. We investigated the effect of bioglass addition on the samples mechanical and biological properties. The samples were analyzed by scanning electron microscopy, optical microscopy, infrared spectroscopy, and microtomography. The effect of bioglass addition on changes in the SBF mineralization process and cell morphology was evaluated. The presence of a spatial microstructure within the scaffolds affects their mechanical properties by reducing them. The tensile strength of the scaffolds compared to filaments was lower by 58–61%. In vitro mineralization experiments showed that apatite formed on scaffolds modified with BG after 7 days of immersion in SBF. Scaffold with Zn-doped BG showed a retarded apatite formation. Innovative 3D-printing filaments containing bioglasses have been successfully applied to print bioactive scaffolds with the surface suitable for cell attachment and proliferation.
