The fabrication of polysaccharide films with metal cation cross-linking was achieved and the mechanical properties of the films were tested.Optimum crosslinking of carrageenan films with calcium ions yielded films with the desired properties of high tensile strength and elongation, transparency and bio-compatibility.Films were also tested for water permeability revealing values similar to other commercial biofilms.Sensing properties of the films were tested by incorporating an organic dye to act as an indicator for acidic gases. Reversible sensing of hydrogen chloride was achieved using this method. This work is currently under preparation for publication.

实现了金属阳离子交联多糖薄膜的制备并测试了薄膜的力学性能。卡拉胶薄膜与钙离子的最佳交联产生了具有高拉伸强度和伸长率、透明性和生物相容性的薄膜。还测试了薄膜的透水性，显示与其他商业生物膜类似的值。通过掺入有机染料作为酸性气体指示剂来测试薄膜的传感特性。使用该方法实现了氯化氢的可逆传感。该作品目前正在准备出版中。
