Polymers are being used in many applications all around the world. However, there are some drawbacks in the properties of polymers that could hamper their usage in certain applications. Therefore, a new material polymer composite was introduced. A polymer composite is a polymer-based material with the addition of a filler. Many researchers have reported the improvement in the properties of a polymer when a filler was introduced. This helps minimize the disadvantages of using a polymer. As a result, polymer composite products can be used in many industries, such as automobile, aerospace, biomedical, and packaging. Fillers derived from natural minerals, such as dolomite, are among the best reinforcement materials for polymeric materials because they are plentiful and low cost, have high rigidity and hardness, and even have tailorable surface chemistry. The use of dolomite as a filler in a polymer composite system has gained increasing attention in recent years after researchers successfully proved that it is capable of improving the mechanical, physical, and thermal properties of various polymeric materials. However, chemical or physical treatment/modification of raw dolomite is needed in order to prepare it as an efficient reinforcing filler. This procedure helps to improve the performance of the resultant polymer composites. This article reviews the usage of dolomite as a filler in a variety of polymeric materials and how it improved the performance of the polymer composite materials. It also highlights several methods that have been used for the purpose dolomite's treatment/modification. Furthermore, the role of dolomite as a co-filler or a hybrid filler in a polymer composite system is also discussed, revealing the great potential and prospect of this mineral filler in the field of polymer composites for advanced applications.
聚合物在世界各地的许多应用中都有使用。然而，聚合物的某些性能存在一些缺点，这可能会妨碍它们在某些应用中的使用。因此，一种新型材料——聚合物复合材料被引入。聚合物复合材料是一种添加了填料的聚合物基材料。许多研究人员报告称，当引入填料时，聚合物的性能会得到改善。这有助于将使用聚合物的缺点降至最低。因此，聚合物复合材料产品可用于许多行业，如汽车、航空航天、生物医学和包装等。源自天然矿物（如白云石）的填料是聚合物材料的最佳增强材料之一，因为它们储量丰富、成本低廉，具有高刚性和硬度，甚至具有可定制的表面化学性质。在研究人员成功证明白云石能够改善各种聚合物材料的机械、物理和热性能之后，近年来，将白云石用作聚合物复合体系中的填料受到了越来越多的关注。然而，为了将原始白云石制备成高效的增强填料，需要对其进行化学或物理处理/改性。这一过程有助于提高所得聚合物复合材料的性能。本文综述了白云石在各种聚合物材料中作为填料的用途，以及它如何改善聚合物复合材料的性能。它还重点介绍了用于白云石处理/改性的几种方法。此外，还讨论了白云石在聚合物复合体系中作为共填料或混合填料的作用，揭示了这种矿物填料在先进应用的聚合物复合材料领域的巨大潜力和前景。
