Research progress of polyurethane foam modified by carbon nano-materials
This paper introduces the research progress of polyurethane foam changed by carbon nano-materials in recent years.The enhancement methods are divided into two categories according to the different ways of introducing carbon nano-materials,namely the internal doping method and the external protective layer method.The action mechanism and modification effect of the two methods are discussed respectively.The shortcomings of polyurethane foam modified by carbon nano-materials and the prospect for the future are discussed.Simple modification operation and reduction of packing agglomeration should be the focus of future research.
