Abstract

The importance of sustainable polymers has increased greatly in the last years since most polymers are derived from non-renewable sources. Sustainable polymers (i.e., biopolymers) such as natural rubber (NR) are proposed as a solution for this concern. A comparative study between NR and deproteinized NR (DPNR) was carried out to elucidate the role of proteins on the network formation and degradation of peroxide cross-linked NR using time-domain NMR experiments. The H multiple-quantum (MQ) NMR experiments provided information on the cross-link density and its spatial distribution, while the actual fraction of non-coupled network defects was obtained by exploiting the Hahn echo approach measured on swollen samples. The results showed that proteins influenced the network formation during the vulcanization process of NR, leading to a higher number of non-elastic network defects and promoting the creation of additional cross-links with a broader spatial distribution. The formation of network heterogeneities in different length scales deeply influences the mechanical properties of NR samples. On the other hand, the proteins showed a pro-oxidant activity on the degradation behavior by accelerating the degradation process of peroxide cross-linked NR.

摘要

在过去几年中，可持续聚合物的重要性大幅提升，因为大多数聚合物来源于不可再生资源。诸如天然橡胶（NR）之类的可持续聚合物（即生物聚合物）被提议作为解决这一问题的方案。开展了一项NR与脱蛋白NR（DPNR）之间的对比研究，以利用时域核磁共振实验阐明蛋白质在过氧化物交联NR的网络形成和降解过程中的作用。H多量子（MQ）核磁共振实验提供了有关交联密度及其空间分布的信息，而未偶联网络缺陷的实际占比则通过对溶胀样品测量的哈恩回波方法获得。结果表明，蛋白质在NR的硫化过程中影响网络形成，导致产生更多数量的非弹性网络缺陷，并促使形成具有更广泛空间分布的额外交联。不同长度尺度上网络不均匀性的形成深刻影响着NR样品的机械性能。另一方面，蛋白质通过加速过氧化物交联NR的降解过程，对其降解行为表现出促氧化活性。
