“…The free radicals are created on the polymer surface may then combine with oxygens and moistures in air to form oxygen functionality including hydroperoxide on the polymer surface. 5 This modified surface is relatively unstable undergoing reorganization, leading to a decrease in surface hydrophilicity. Therefore, subsequent modification by grafting of AA was carried out to maintain the surface functionality.…”

“…O envelhecimento da superfície do polímero modificado é caracterizado pelo retorno da hidrofobicidade com o decorrer do tempo, ou seja, ao estado de molhabilidade anterior ao tratamento. Embora existam muitos estudos de envelhecimento de polímeros tratados por plasma [16,[21][22][23] , os polímeros tratados por VUV têm sido negligenciados neste contexto [24] . Um fator importante na análise da recuperação hidrofóbica é o próprio tratamento, pois dependendo das condições e do tipo de tratamento a recuperação hidrofóbica pode ser mais ou menos lenta [16,25,26] .…”

“…These free radicals then combine with oxygen or moisture in air when they are exposed to the atmosphere. 10 Radio-frequency (RF) plasma (13.56 MHz) treatment was used in this study to modify the surface of polycarbonate to improve its wettability. The objective was to develop an empirical model of the process and to make a more precise assessment of the optimum operating conditions for the governing factors.…”
