Although chitosan has many advantages and wide application prospects, it also has some disadvantages and limitations.
First, chitosan has poor stability in some specific environments. For example, chitosan is susceptible to deliquescence, which affects its stability and durability in practical applications. Especially in the application of preparing waterproof materials, adhesives, etc., deliquescence may lead to the performance degradation of chitosan products. In addition, chitosan is also susceptible to environmental factors such as temperature and humidity, resulting in poor stability.
Secondly, the purity of chitosan is also an issue. The extraction process is relatively complex, and it is difficult to improve the purity, which may lead to the limitation of the effect in some application fields.
Furthermore, when chitosan is used as a coating carrier, its dissolution rate is relatively slow, which may affect the absorption and utilization efficiency of the drug. Although chitosan can accelerate drug release and absorption, the limitation of its dissolution rate still needs to be considered.
In addition, chitosan may cause allergic reactions in some cases and is not suitable for use in all populations.
In addition, the application range of chitosan is also limited by its applicable pH range. It can only be dissolved in acidic solution, easy to lose and degrade under acidic conditions, and the selectivity of metal ions is not good.
In summary, although chitosan has many advantages, it is still necessary to pay attention to its shortcomings and limitations such as stability, purity, dissolution rate, allergic reaction and pH range in practical applications. When using chitosan, it is necessary to consider comprehensively according to specific application scenarios and requirements.
