 Full text | Abstract: A polyester fabric was treated by corona discharges. Surface modification was carry out using a laboratory prototyped device. A quantity of acid groups formed on the surface of fibres was determined and normalised activation energy [Ej] was selected, required to apply the Layer-by-Layer (L-b-L) method. Contact angles were established and components of the surface free energy were calculated for the samples activated. A significant growth in polar components of the surface free energy was found, caused by the corona discharges. The L-b-L method was used for deposition nano-layers of poly(allylamine hydrochloride) [PAH] and polyacrylic acid [PAA]. Using the test dye method, it was found that the method can be applied to polyester fabrics activated by corona discharges and modified by the deposition of polymer complex nano-layers. |
