摘要: If self-healing materials can be prepared via simple technology and methods using nontoxic materials, this would a great step forward in the creation of environmentally friendly materials. In paper, specific structural parameters various hydrogen bonds between chitosan (CS) polyacrylic acid (PAA) were calculated. Then, multilayer polyelectrolyte films fabricated with CS PAA based on layer-by-layer (LbL) self-assembly at different pH values. The possible influence (CS/PAA) × 30 film was investigated. results show that interactions PAA, swelling capacity, microstructure, wettability, ability are all governed by solution. When value solution is 3.0, (CS3.0/PAA2.8) has fine-tuned interactions, network-like structure, good ability, hydrophilicity, excellent ability. This promises to greatly widen future applications bio-materials.
