Abstract

Rod-like chains (RLCs) recently came back in the spotlights due to the development of new systems and applications such as the demand for the replacement of flexible polymers as viscosifiers or the development of suited extra cellular matrices. The advantage of RLC systems is their high mechanical susceptibility. However, the interpretation of the mechanical properties is not straightforward as slow dynamics can be due to extreme sterical hindrance, glassy behavior, or due to attractions that yield gel formation. In this review we identify the open questions for repulsive RLCs and discuss how recent developments in terms of new model systems, experiments, and theory help to identify the huge impact that the morphology of the RLCs can have on the mechanical properties.

棒状链在各向同性相中的流变学

棒状链（rlc）最近重新成为人们关注的焦点，这是由于新系统和新应用的发展，例如需要替代柔性聚合物作为增粘剂或开发合适的细胞外基质。RLC系统的优点是机械敏感性高。然而，机械性能的解释并不简单，因为缓慢的动力学可能是由于极端的位阻，玻璃状行为或由于产生凝胶形成的吸引力。在这篇综述中，我们确定了排斥性rlc的开放性问题，并讨论了新模型系统、实验和理论方面的最新发展如何帮助确定rlc的形态对力学性能的巨大影响。

期刊介绍： Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
