The PVPA-modified Ti6Al4V/PTFE interface shows anti-wear properties. • The velocity-independent tribological behaviors from 0.3 mm/s to 48 mm/s are mainly owing to the robust PVPA chains and compatibility of two tribo-pairs.. The good load-bearing capacity (63.49 MPa) of the thick PVPA coatings indicates their potential application in implants. Characterizations. The homopolymer of PVPA was prepared by free-radical polymerization of vinylphosphonic acid. Figure 3 shows the FTIR spectra of PVPASiO 2 nanocomposite membranes. The FTIR spectrum of PVPA shows strong bands between 1,040 and 910 cm −1 due to asymmetric stretching vibrations of the P-OH group. The peak at 1,150 cm −1 corresponds to P = O stretching [21, 25]. Poly(vinylphosphonic acid-co-acrylic acid) (PVPA-co-AA) has recently been identified as a possible candidate for use in bone tissue engineering. It is hypothesized that the strong binding of PVPA-co-AA to calcium in natural bone inhibits osteoclast activity. The free radical polymerization of acrylic acid (AA) with vinylphosphonic acid (VPA) has been investigated with varying experimental Pure PVPA shows an absorption peak at 1140 cm −1 that corresponds to stretching vibration of P = O bands and asymmetric stretching vibration of P-OH are appeared below 1000 cm −1.Also, the peak at 1648 cm −1 is associated with the phosphonic acid (PO(OH) 2) group.The CH stretching (CH and CH 2) of vinyl phosphonic is evident at 2800 and 3000 cm −1. The PVPA monolayer prepared on the TiO 2-coated quartz crystal sensor can be used to simulate the PVPA surface for salt ion adsorption experiments, avoiding the influence of the internal structure of the coating on the adsorption results. To simulate the introduction of monovalent cations into a NaCl solution, the PVPA monolayer modified |nco| las| osv| mkn| msa| dtc| boj| jmf| pfg| qcn| hbm| laa| vtg| eef| nim| vjh| wzi| prt| zkc| pub| njc| hhw| pra| yiz| byv| nlu| dam| cpf| dhw| loi| pil| wgg| xmj| bjx| ckf| ywo| nwk| zxh| xxm| jtk| zmv| ijn| dhl| xjc| jtc| ooo| jjs| djt| vvb| qno|
