In the originally published paper, there was an error in Figure 1 as published. To reveal chemical groups and phase composition of the samples, it had been inadvertently replaced by the wrong sample number image of e and f when we used AI software to typeset for manuscript preparing. The corrected Figure 1 is shown below.
At the same time, there was an error in Figure 3 as published. To reveal the element distribution on the samples, it had been inadvertently replaced by the wrong sample number image of i, j, k, l when we used AI software to typeset for manuscript preparing. The corrected Figure 3 is shown below.
The authors apologize for the error and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
Figure 1. SEM image of Ta (a) and SN (b) particles, DLS of particle size distribution of Ta (c) and SN (d), and FTIR (e) and XRD (f) of Ta, SN, PEEK, TPC and SPC; * is characteristic peaks of PEEK, ● is characteristic peaks of Ta and ▼ is characteristic peaks of SN.
