摘要

摘要本研究采用衰减全反射-傅立叶变换红外光谱法测定了不同种类天然橡胶的脂质含量。考虑了这些量与天然橡胶化合物的拉伸性能之间的相关性。所有情况下的Pearson相关系数均大于-0.9，这证实了模型是可接受的。在案例研究中，这些模型被应用于拉伸性能的估计。据观察，拉伸强度、断裂伸长率、模量100%和模量300%可以分别预测约4%、17%、18%和18%的误差。这是一种在制备化合物之前评估拉伸性能的简单、快速和无损的方法。

Correlations between lipid contents of natural rubber and tensile properties of natural rubber-based compound, using attenuated total reflection Fourier transform infrared spectroscopy

Abstract In this study, the lipid contents of different kinds of natural rubber were measured by attenuated total reflection–Fourier transform infrared spectroscopy. The correlation between these amounts were considered with the tensile properties of natural rubber compounds. The Pearson correlation coefficients were more than −0.9 for all cases, which confirms that the models are acceptable. These models were applied for the estimation of tensile properties in the case study. It was observed that the tensile strength, elongation at break, modulus 100%, and modulus 300% can be predicted by errors of about 4%, 17%, 18%, and 18% respectively. This is a simple, fast, and nondestructive way to estimate the tensile properties before the compound preparation.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
