Surface structural characterisation of three different starch-based blends (with poly[ethylene-co-(vinyl alcohol)], cellulose acetate and polycaprolactone) was carried out. The results show that there is a difference between the bulk and the surface composition of all studied blends. Two different hypotheses were investigated - predominant presence of a synthetic component on the surface and possible inter- and/or intramolecular bonds. The results were related to previous data for cell behaviour on those materials. It was found that both surface hydrophilicity and surface functionality are of great importance for cell adhesion and growth on starch-based biomaterials.
对三种不同的淀粉基共混物（与聚乙烯-共-（乙烯醇）、醋酸纤维素和聚己内酯）进行了表面结构表征。结果表明，所有研究的共混物的本体和表面组成之间存在差异。研究了两种不同的假设——表面上合成组分的主要存在以及可能的分子间和/或分子内键。结果与之前关于细胞在这些材料上行为的数据相关。发现表面亲水性和表面功能性对于淀粉基生物材料上的细胞粘附和生长都非常重要。
