“…Natural rubber (NR), one of the most important biosynthesized polymers displaying excellent chemical and physical properties, finds widely application in various areas [1][2][3]. Particularly, as an chemical-free biomacromolecule, natural rubber latex (NRL) has been used in manufacturing medical products such as medical gloves, condoms, blood transfusion tubing, catheters, injector closures and safety bags due to its excellent elasticity, flexibility, anti-virus permeation, good formability and biodegradability [4][5][6]. More recently, with the worldwide spread of the epidemic diseases such as acquired immure deficiency syndrome (AIDS), hepatitis B, severe acute respiratory syndrome (SARS) and avian influenza A (H5N1), it becomes increasingly important and urgent to develop high performance NRL protective products.…”
