  • 需要先进的伤口护理材料来解决出血控制和身体扩张的问题.

研究的目的:

  • 开发一种新型复合材料,将静血特性与形状记忆聚合物泡结合起来,以改善伤口管理.
  • 制造和描述两个不同的复合材料配方:涂层复合材料和注入复合材料.
  • 评估开发材料的静血疗效,液体吸收和降解概况.

主要方法:

  • 复合材料的制造,通过将静血纳米复合材料与形状记忆聚合物泡相结合.
  • 开发了两种配方:纳米复合材料的外部涂层和孔隙注入.
  • 评估液体吸收,形状记忆扩张,静血性能 (凝结时间) 和在降解条件下的材料稳定性.

主要成果:

  • 这两种复合材料配方均表现出形状记忆泡扩张特性.
  • 与仅注入复合材料和泡相比,涂层复合材料显示显著改善液体吸收 (>2倍).
  • 涂层复合材料减少了大约20%的凝血时间,而输注复合材料在更长的距离 (高达2倍) 上增强了凝血.

结论:

  • 开发的复合材料提供适合非压缩性伤口的模块化静血功能.
  • 涂层复合材料在快速凝固和液体吸收方面表现出色,而注入复合材料则提供扩散凝固和持续的机械完整性.
  • 这些先进的材料显示出在战场创伤和其他关键出血场景中改善结果的巨大潜力.
