“…It can be seen that the surface resistance of the SWCNT/PET lm was greatly reduced to 120 Ω/□ when a SWCNT thin lm with a transparency of ~50% was employed. This low sheet resistance is about 4 times lower than that of the best value previously reported [5], which fully meet the demands of antistatic packaging applications [39]. The dramatically decreased surface resistance is attribute to the embedded SWCNT network shown in Fig.…”

Single-wall carbon nanotubes (SWCNTs) with excellent physicochemical properties are considered a promising candidate for the electrical and mechanical reinforcements of polymers. However, the poor dispersion of SWCNTs in plastics seriously limits their application and the performance enhancement achieved. Here we coat free-standing, highly conductive SWCNT film onto the surface of polyethylene terephthalate (PET) film by a hot-pressing method. Due to the uniform SWCNT network structure and strong interfacial interaction, the SWCNT/PET hybrid film showed notably enhanced electrical and mechanical properties even though with a very low SWCNT weight fraction of 0.066%. The surface square resistance of the SWCNT/PET film decreased to 120-140 Ω/□ from 1016Ω/□. In addition, the Young's modulus and tensile strength of the SWCNT/PET film reached 4.6 GPa and 148 MPa, which are 31.3% and 24.4%, respectively, higher than pure PET film. The SWCNT/PET film shows excellent mechanical durability and thermal stability, demonstrating their potential use as an antistatic material.

The electrostatic voltage can seriously affect some precise electronic components and trigger safety issues 15,16 .

This paper reported the high strength and antistatic polyethylene terephthalate (PET) bead foam with a typical segregated structure prepared by supercritical carbon dioxide (scCO2) foaming and microwave selective sintering. Firstly, carbon nanotubes (CNTs) were coated on the surface of PET pellets, and then the composite foam with segregated structure was prepared via scCO2 foaming in a confined mold. The interfaces among PET foamed beads were further sintered by utilizing the selective heating behaviors of microwave, which greatly enhanced the interfacial strength and thus the overall mechanical strength of bead foam. The final composite foam showed an electrical conductivity of 0.004 S/m with an extremely low CNTs loading of 0.138 vol%, and its mechanical strength reached as high as 10.44 MPa, far superior to the composite without microwave treatment. Thus, the problem in the welding of PET bead foams and antistatic properties could be solved. The effect of the foaming conditions on the structure and properties of PET foam were systematically investigated, providing a novel method for the preparation of high strength and antistatic engineering plastics composite foam.

The use of biodegradable polymers is an interesting way to reduce the polymeric waste accumulation in the environment. However, the addition of fillers to biodegradable polymer matrices may decrease their biodegradability. Glassy carbon (GC) is a promising carbon material that can be employed as a filler in the production of antistatic packaging utilized to protect electronic components. The use of a biodegradable polymeric matrix such as poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) can be an excellent alternative for the preparation of green composites to be used in these packages. This work aims to evaluate the effect of the GC addition and the GC particle size on the biodegradability of the PHBV matrix, as well as to study the result of the employment of a previous photodegradation treatment on the biodegradation in aqueous medium of PHBV/GC composites. Scanning electron microscopy, residual weight measurement (%) and surface roughness showed that GC does not interfere negatively with PHBV biodegradability. Differential scanning calorimetry analysis and residual weight measurement permitted to suggest that the increase in the crystallinity degree of PHBV and PHBV/GC samples occasioned by the ultraviolet radiation hindered the water and enzyme access to the bulk of the materials, decreasing the biodegradability.
