摘要：

Biodegradable polymer foils made by extrusion of a mixture of potatoes and maize starch were coated by plasma polymerization of hexamethyldisilazane (HMDSN) and hexamethyldisiloxane (HMDSO) in order to prevent the direct action of water while retaining the biodegradability of the foils as much as possible. Foils coated at higher monomer concentrations in the argon feed (17% and 11% for the HMDSN and the HMDSO, respectively) and at higher RF power (5 W and 2 W, respectively) became highly hydrophobic (water contact angle 97 degrees and 103 degrees, respectively), i.e. they showed a good water repellency. Beside a small increase of the induction period, the biodegradability remained unaffected by the coatings. (C) 1998 Elsevier Science S.A.
