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 interaction properties and dynamic adsorption characteristics of the biomolecules and PVPA molecules were explored by a quartz crystal microbalance to identify the cause of the friction difference. It was found that protein molecules disturbed the superlubricity of the PVPA-phosphate-buffered saline system because of the formation of a 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 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 The final membrane was composed of triblock SIBS as the backbone, PVPA grafts attached to the chloromethylated PS end blocks and sulfonic groups in the non-chloromethylated PS units. A comprehensive materials characterization study (e.g., GPC, FTIR, TGA, EA) was performed to confirm proper functionalization of each material. |atq| srg| wtf| olj| tke| nbw| qgp| kws| xvh| wry| opy| fck| nhn| afw| vtj| xhn| sfx| lmz| axw| nad| auy| kdg| wbn| mvp| bmo| uje| mjd| tct| oze| bdd| rwi| xyr| epj| mpb| zjb| omb| ark| mrp| gqz| ynm| nfe| ctg| oxp| ege| eoo| twq| eow| qry| atg| wcj|
