A miniature twin screw extruder is required for processing of polymers with other polymers or with specialty nanomaterials which may be synthesized in-house or acquired from suppliers. Polymer materials are used in many applications and over 2/3 of materials that people touch every day is made of polymers. Polymer nanocomposites (polymer matrices holding nanofillers) have drawn much attention as they benefit from inherent properties of both polymer matrix and nanofiller, and they are considered materials of the future and can access property combinations previously unachievable with single materials. Nanocomposites are currently used in high-tech applications. It is currently a $2 Billion dollar industry, and is predicted to triple in size in the next three years, yet there is little understanding about how manufacturing and structure affects the final properties. A more developed field is polymer blends (a mixture of two or more polymers) and it is estimated that over 80% of plastic materials sold today are actually blends. Our group is dedicated to the design of novel polymer blends and nanocomposites containing effectively dispersed functional nanofillers and polymer phases, for a wide range of applications such as electrical conductivity, charge storage, barrier properties, structural and electromagnetic interference shielding.

微型双螺杆挤出机需要与其他聚合物或特殊纳米材料一起加工聚合物，这些材料可以在内部合成或从供应商处获得。聚合物材料在许多应用中都有使用，人们每天接触的材料中有超过2/3是由聚合物制成的。聚合物纳米复合材料（含有纳米填料的聚合物基体）因其具有聚合物基体和纳米填料的固有特性而备受关注，被认为是未来的材料，可以实现以前单一材料无法实现的性能组合。纳米复合材料目前应用于高科技领域。目前，它是一个价值20亿美元的产业，预计在未来三年内规模将增加两倍，但人们对制造和结构如何影响最终性能知之甚少。一个更发达的领域是聚合物共混物（两种或两种以上聚合物的混合物），据估计，今天销售的80%以上的塑料材料实际上是共混物。我们的团队致力于设计新型聚合物共混物和纳米复合材料，其中包含有效分散的功能纳米填料和聚合物相，用于广泛的应用，如导电性，电荷存储，屏障性能，结构和电磁干扰屏蔽。
