Studies Conducted at Sichuan University on Succinic Acid Recently Reported [Enhanced toughness and strength of conductive cellulose-poly(butylene succinate) films filled with multiwalled carbon nanotubes]
By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on Succinic Acid have been published. According to news reporting out of Chengdu, People's Republic of China, by NewsRx editors, research stated, "Cellulose (CE) composite films with high tensile strength, modulus, remarkable elongation as well as excellent electrical conductivity were successfully prepared by dispersing poly(butylene succinate) (PBS) and multiwalled carbon nanotubes (MWCNTs) in CE matrix via the help of ionic liquid 1-allyl-3-methylimidazolium chloride. Fourier transform infrared spectroscopy and differential scanning calorimetry results verified that a physical interaction junction existed between PBS and CE."
Our news journalists obtained a quote from the research from Sichuan University, "Scanning electron micrograph (SEM) showed that the low content PBS was uniformly dispersed in CE matrix, leading to a tough and ductile fractured surface. The elongation at break of CE composite film with 1 wt% PBS was increased to 25.9 %, which showed an increase of 325 % compared to that of neat CE film (6.07 %). But high-content PBS acted as the structural defect in the CE matrix. MWCNTs were further added to improve the mechanical and conductive properties of the composite film. The tensile strength and Young's modulus of MWCNT/CE-PBS composite film with 4 wt% MWCNTs were respectively increased by 33.6 and 140 % compared to CE-PBS film."
According to the news editors, the research concluded: "The electrical conductivity of MWCNT/CE-PBS film was also improved by 8-9 orders of magnitude from 2.5 x 10(-14) to 1.3 x 10(-5) S/m."
