Apatite coating on hydrophilic polymer-grafted poly(ethylene) films using an alternate soaking process

Preparation of hierarchically organized calcium phosphate–organic polymer composites by calcification of hydrogel

“…However, in past studies using these techniques, apatite was deposited only on the surface of the fibers exposed to the precursor solution. An alternative soaking process in calcium and phosphorous solutions provided the HAp formation in a three-dimensionally structured organic hydrogel matrix at ambient temperature [18,19]. An ordered composite powder of HAp and organic molecules was also prepared through self-organization by interplay at the organic-inorganic interface [20][21][22][23][24][25][26][27][28].…”

Preparation and biological evaluation of hydroxyapatite-coated nickel-free high-nitrogen stainless steel

“…HAp has been formed on metals and polymers using various techniques [15,16], such as dip coating [17,18], electrophoretic deposition [19,20], the alternate soaking process [21][22][23][24], thermal spraying [25,26], dynamic mixing [27], RF magnetron sputtering [28,29], pulsed laser ablation [30] and low-voltage deposition [31]. The coating temperature of HNS during HAp formation is important, because the release of N 2 from HNS by high-temperature treatment causes the phase change from austenite to ferrite [32,33].…”

P(EMA-co-HEA)/SiO2 hybrid nanocomposites for guided dentin tissue regeneration: structure, characterization and bioactivity.

“…Taguchi et al [101] developed a simple method that combines the modification of the surfaces with functional groups effective for the apatite nucleation and a rapid precalcification. In a first step, polyethylene substrates were surface-grafted with hydrophilic poly(acrylic acid) or poly(acryl amide) to introduce carboxyl or amide groups, respectively.…”

“…After 14 days in SBF, the peaks corresponding to the coatings are poorly resolved and the broad band corresponding to the hybrid predominates in the three spectra (10-25º). After 35 days, the broad peak at 32 to 34º and the peak at around 26º attributed to XRD HAp crystals [40,50,54,60,61,93,101,102] are well defined. The intensity of these peaks decreases in the order: H15 > H30 > H00.…”
