Special Issue Information

Dear Colleagues,

Through microstructure design, viscoelastic composite materials (VCMs) may exhibit effective properties that conventional materials may not possess, such as high damping and high stiffness simultaneously. Internal processes, in addition to microstructure, may also greatly affect the properties of VCMs. In industry, linear and nonlinear viscoelastic properties have found a wide range of applications, including the reduction of unwanted vibrations and noise. This Special Issue of Polymers, entitled “Viscoelastic Composite Materials”, aims to provide a forum for original research, critical reviews, and perspectives in the area of viscoelastic composite materials and their applications in academic and industrial sectors.

Topics of interest include, but are not limited to:

  • polymer–matrix composites;
  • metal–matrix composites;
  • composite materials with a polymeric inclusion;
  • asphalt and related composite materials;
  • cellular solids;
  • coupled-field properties;
  • static and dynamic properties;
  • waves in viscoelastic composite materials;
  • viscoelastic properties of metamaterials.

Slopes with carbonaceous mudstone (CM) are widely distributed in the southwest of China and have experienced numerous geological disasters in special climate, especially in rainfall conditions. Therefore, novel materials to stabilize CM slopes have attracted increasing interests. However, developing ultra-stable and cost-effective additives for CM slopes is still a great challenge. Herein, a hydrophobic polymeric material (polyvinylidene fluoride, PVDF) is investigated as an additive to enhance the mechanical strength and long-time stability of CM slopes. The PVDF is uniformly dispersed in CM matrix via interfacial interaction. The contact angle of the PVDF-modified carbonaceous mudstone (PVDF-MCM) can reach as high as 103.95°, indicating an excellent hydrophobicity. The unconfined compressive strength (UCS) and tensile strength (TS) of PVDF-MCM have been intensively enhanced to 4.07 MPa and 1.96 MPa, respectively, compared with ~0 MPa of pristine CM. Moreover, the UCS and TS of PVDF-MCM remain at 3.24 MPa and 1.03 MPa even after curing for 28 days in high humidity conditions. Our findings show that the PVDF can improve the hydrophobicity of CM significantly, which leads to super mechanical stability of PVDF-MCM. The excellent performance makes PVDF a promising additive for the development of ultra-stable, long-lifetime and cost-effective carbonaceous mudstone slopes. Full article
