3D printing high interfacial bonding polyether ether ketone components via pyrolysis reactions

Recently, 3D-printed polyether-ether-ketone (PEEK) components have been shown to offer many applications in state-of-the-art electronics, 5G wireless communications, medical implantations, and aerospace components. Nevertheless, a critical barrier that limits the application of 3D printed PEEK is their weak interfacial bonding strength. Herein, we propose novel method improve this unsatisfied situation via interface plasticizing effect benzene derivatives obtained from thermal pyrolysis trisilanolphenyl polyhedral oligomeric silsequioxane (POSS). Based on method, strength filaments interlayers POSS/PEEK can reach 82.9 MPa 59.8 MPa, respectively. Moreover, enhancing mechanism products derived POSS characterized using pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS), Fourier transform infrared spectroscopy (FTIR), X-ray computed tomography (X-CT). Our proposed strategy broadens design space for developing additional materials with satisfactory
