Abstract: Multifunctional coating films that can be applied in liquid form are provided for compressing, sealing, covering and preserving surfaces. The films include a composition of polysaccharide materials and/or homo- or heteroglycan water-soluble polysaccharide derivatives, polyol spacers, and crosslinkers with carbonyl or carboxylic function(s). As-applied, the composition is water-soluble and reactive, but after hardening it is capable of absorbing water or swelling, impermeable to water vapour, stable against water and UV and can be biologically degraded in a controlled manner. By reacting polysaccharide materials, polysaccharide derivatives and polyol spacers with cross linkers having carbonyl or carboxylic function(s), mechanically stable flexible films are obtained, which retain their mechanical properties up to a foreign material content of 80%. The films can swell in a controlled manner and can bind up to 75% water relative to their dry weight, corresponding to the degree of crosslinking and the spacer that is used.
Abstract translation: 可应用于液体形式的多功能涂膜用于压缩，密封，覆盖和保存表面。 膜包括多糖材料和/或均聚物或异源聚糖水溶性多糖衍生物，多元醇间隔物和具有羰基或羧基官能团的交联剂的组合物。 应用时，组合物是水溶性的和反应性的，但是在硬化之后，其能够吸收水分或膨胀，对水蒸气不透水，对水和UV具有稳定性，并且可以以受控的方式生物降解。 通过使多糖材料，多糖衍生物和多元醇间隔物与具有羰基或羧酸官能团的交联剂反应，获得机械稳定的柔性膜，其保持其机械性能达80％的异物含量。 膜可以以受控的方式膨胀，并且相对于其使用的交联度和间隔物相对于其干重可以结合高达75％的水。
