精细功能陶瓷的若干发展趋势

概括了分析自９０年代初以来精细功能陶瓷的发展趋势，提出了一些相关的研究领域。     

生物驻极体材料对细胞生长的影响

研究天然生物高分子（如胶原）对组织损伤修复的影响．从猪皮中提取的Ｉ型胶原通过ＴＳＤＣ技术极化，并测试其驻极化前后的ＴＳＤＣ变化．将极化的材料用于细胞培养．得到了细胞生长曲线．实验证实，极化后的材料能加速细胞的生长．有可能用作生物医用材料．     

单极性复合生物驻极体材料及其对细胞生长的影响

为了探索复合生物驻极体材料的带电性能对细胞生长的影响，研制了几种不同配比的胶原／壳聚糖复合生物驻极体材料，分析了它们的ＴＳＤＣ图谱（热刺激去极化电流谱），筛选出了一种性能较好的胶原／壳聚糖复合生物驻极体材料，它在极化状态时，主峰温度和电流分别为３７℃和２×１０－９Ａ细胞培养实验研究发现，当该材料负极化时，能够有效地促进正常细胞的生长；当材料正极化时，能够抑制癌细胞的生长这表明，对复合生物驻极体材料进行合理设计，将对临床医学应用具有重要意义     

A study on bioelectret collagen

The aim of this paper is to study the properties of collagen, which is used as a promoting bioelectret for wound healing. So first of all, a bioelectret material based on collagen was prepared, then the processes of thermally stimulated discharge of collagen were measured under different conditions. Cell culture studies were used in the determination of the suitability of this kind of bioelectret as surfaces for the attachment and growth of cells. Some results show the potential use of bioelectret collagen in soft tissue wound healing. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 64: 267–271, 1997
