Natural rubber (NR) latex was initially deproteinized, then, the interactions between chitin nanocrystals (ChNCs) and deproteinized natural rubber (DNR) latex particles in an aqueous system and the properties of DNR/ChNCs composites were investigated. Composite films were obtained by casting and evaporating off the prevulcanized DNR/ChNCs complexation rather than simply mixing of DNR latex and ChNCs suspension. The results of DLS and TEM confirmed that this kind of complexation was formed between negative charged DNR and positively charged ChNCs by self‐assembly. The tensile strength of composite films containing 4 wt% ChNCs was 25.00 ± 1.42 MPa, which was 3.11 multiples of the pure pre‐vulcanized DNR. DNR/ChNCs composite films could provide excellent mechanical properties and avoid allergies caused by proteins in NR latex.

几丁质纳米晶体的网状自组装结构增强了脱蛋白的天然橡胶乳胶膜

首先对天然橡胶（NR）乳胶进行脱蛋白处理，然后研究几丁质纳米晶体（ChNCs）与脱蛋白的天然橡胶（DNR）乳胶颗粒在水性体系中的相互作用以及DNR / ChNCs复合材料的性能。通过流延并蒸发掉预硫化的DNR / ChNCs络合物，而不是简单地将DNR胶乳和ChNCs悬浮液混合，可以获得复合膜。DLS和TEM的结果证实了这种复合是通过自组装在带负电荷的DNR和带正电荷的ChNC之间形成的。包含4 wt％ChNCs的复合膜的拉伸强度为25.00±1.42 MPa，是纯预硫化DNR的3.11倍。DNR / ChNCs复合膜可提供出色的机械性能，并避免由NR乳胶中的蛋白质引起的过敏。
