Effect of Humidity on Metallizing on Polyphenylene Sulfide (PPS) with Atmospheric UV Treatment

“…This reduction in the peak intensity means that the crystal structure had collapsed and become amorphous. Reactions induced by UV treatment generally include functional group formation, recrystallization, crosslinking, and molecular chain scission [4,[20][21][22]. This is consistent with the abovementioned XPS analysis, which revealed an increase in the amount of C-O and C=O bonds and a relative decrease in the C-H and C-C ones after UV pretreatment under wet conditions.…”

“…This indicates that the introduction of O-containing functional groups was further promoted by UV treatment under wet conditions. The adhesion between the plating film and resin can be explained by two mechanisms: physical adhesion and chemical adhesion [4,19]. In the physical mechanism, as typified by the anchor effect, a plating film is formed on the rough surface of the resin and gets caught on the rough surface.…”

“…In recent years, plating on engineering plastics has been investigated using a construction method that excludes harmful chemicals [1][2][3][4]. There are three reasons for this.…”

Electroless Plating Catalyst Performance of a Cationic Moiety Bearing Palladium Complex

“…For these reasons, many reports on new resin surface modification methods have been published. [1][2][3][4][5][6] The common feature of these surface modification methods is that they focus on generating hydrophilic functional groups such as hydroxyl and carboxylate groups on resin surface by reactive oxygen. In traditional roughing methods, even if adhesion between resin and palladium catalyst or electroless plated films was weak, the electrolytic plated film are physically anchored to the resin, therefore no problem would have been noticeabled.…”
