Biodegradation of poly(ε-caprolactone)–polycarbonate blend sheets

Degradation of poly(ε-caprolactone) by a thermophilic bacterium Ralstonia sp. strain MRL-TL isolated from hot spring

“…It belongs to the class b-proteobacteria. The degradation of PCL has been studied by various researchers (Hirotsu et al, 2000;Khatiwala et al, 2008;Li et al, 2012) as well as under thermophilic conditions (Sanchez et al, 2000;Nakasaki et al, 2006;Tseng et al, 2007;Chua et al, 2013). However, there are limited reports on degradation of polyesters by thermophilic strain from genus Ralstonia as well as the depolymerases from Ralstonia sp.…”

Fluorinated-plasma coating on polyhydroxyalcanoate PHBV

“…Improvement of the biodegradation of polyalcanoates can be achieved by increasing the hydrophilicity of the surface to facilitate diffusion of the enzymatic aqueous media towards the bulk. Argon and oxygen plasma for grafting polar groups and acrylic acid plasma for depositing an hydrophilic layer, were most widely investigated [9,10]. However, modification of the polyalcanoate surface did not lead to a more rapid biodegradation.…”

Surface modification of non-woven fabric by DC pulsed plasma treatment and graft polymerization with acrylic acid

“…Oxygen plasma can introduce reactive hydroxyl and carboxyl groups and other polar functions to a substrate surface [11,12]. A higher grafting efficiency was achieved using oxygen plasma when compared to other atmospheres [13], and surface modification with oxygen plasma is effective in promoting the surface hydrophilicity as reported in many studies [14][15][16].…”
