<abstract xmlns="http://www.w3.org/1999/xhtml">In this paper we report a study on influence of radio-frequency (RF) plasma induced with electron cyclotron resonance (ECR) on multiblock copolymer containing butylene terephthalate hard segments (PBT) and butylene dilinoleate (BDLA) soft segments. The changes in thermal properties were studied by DSC. The changes in wettability of PBT-BDLA surfaces were studied by water contact angle (WCA). We found that ECR-RF plasma surface treatment for 60 s led to decrease of WCA, while prolonged exposure of plasma led to increase of WCA after N2 and N2O2 treatment up to 70°–80°. The O2 reduced the WCA to 50°–56°. IR measurements confirmed that the N2O2 plasma led to formation of polar groups. SEM investigations showed that plasma treatment led to minor surfaces changes. Collectively, plasma treatment, especially O2, induced surface hydrophilicity what could be beneficial for increased cell adhesion in future biomedical applications of these materials.</abstract>
