| 摘 要： | 通过在铝合金表面制备等离子体聚合物薄膜以减少蛋白质吸附,提高铝合金生物相容性.采用四乙二醇二甲醚为有机试剂,在电子回旋共振低温微波等离子体条件下,在铝合金表面制备了一层涂层,用X-ray光电子能谱、衰减全反射红外光谱和血浆蛋白吸附试验对涂层进行分析表征.结果表明:铝合金表面沉积的涂层均匀、致密,其化学组成为类PEG结构,主要聚集大量碳氢和碳氧极性键;与改性前相比,等离子体沉积在铝合金表面的类PEG涂层能够有效抵抗蛋白质吸附.

| Abstract: | Cold plasma surface modification technology is a promising approach to control non-specific protein adsorption and cell adhesion on biomaterials.A uniform and compact thin solid film on aluminum alloy surfaces under tetraglyme microwave cold-plasma from electron cyclotron resonance.Research of XPS and ATR-FTIR spectra indicated that the plasma modification resulted in the formation of the polyethylene glycol(PEG)-like structures of the deposited thin coatings,with abundance of carbon-hydrogen and polar carbon-oxygen linkages aggregating on the surfaces.Compared to the unmodified surfaces,the plasma-treated surfaces effectively offer protein resistance. |
