Functionalisation of PAA radiation grafted PVDF

“…In agreement with previous studies (19,30,31), the FTIR spectrum of PVDF-g-PAA (Fig. 1) shows a characteristic absorption band at 1,726 cm −1 attributed to the C=O stretching vibration of the carboxylic acid of PAA.…”

Evaluation of the antifouling and photocatalytic properties of poly(vinylidene fluoride) plasma-grafted poly(acrylic acid) membrane with self-assembled TiO2

“…The subsequent decrease could be attributed to the prevalence of homopolymerization at 70 • C. PAA formation was probably very rapid at elevated temperature, leaving less monomer to diffuse on the membrane. A similar trend was found in the study of Betz et al [29], which reported that more PAA homopolymers and less grafts were produced at 80 • C than 60 • C. Fig. 6c shows the progress of graft polymerization under optimized conditions thus far.…”

Tailoring bulk and surface grafting of poly(acrylic acid) in electron-irradiated PVDF

“…Therefore, when the homopolymer is formed in high quantity in solution, it can diffuse in the graft copolymer. If not entirely extracted from the PAA grafted films, erroneous grafting yield is measured [13]. Consequently, addition of inhibitor to the AA solution is needed to minimize homopolymerization.…”

“…In the latter approach, various techniques were used for hydrophilic monomer (e.g. acrylic acid) grafting onto various hydrophobic polymers: pulsed plasma [6][7][8], corona discharge [9], ozone treatment [2], gamma radiation [8,[10][11][12], electron-beam irradiation [13,14]. In semicrystalline polymers, ionizing radiation has the advantage of inducing the formation of stable radicals able to initiate the monomer grafting in a second step.…”
