Hydrothermal and mechanically generated hemp hurd nanofibers for sustainable barrier coatings/films

نویسندگان

چکیده

Residual hemp (Cannabis sativa) hurd fibers obtained from hydrothermal, carbonate, and kraft treatments were the resources used to obtain lignocellulosic nanofibers (LCNF) by using an ultra-fine friction grinder. The morphological, crystallinity, chemical characteristics of nanocellulose films carried out SEM, XRD, EDX ToF-SIMS. Water barrier properties same measured in terms water contact angle, vapor permeability (WVP) absorption. found be dependent not only on lignin content distribution, but also film density porous structure. LCNF coatings showed much higher angle (WCA) (80°-102°) than produced bleached CNF. WVP was more content. Overall, LCNF-based derived residual can contribute a circular economy sustainability.

Enrichment of Cellulosic Waste Hemp (Cannabis sativa) Hurd into Non-Toxic Microfibres

In this study a largely available lignocellulose feedstock hemp (Cannabis sativa), obtained as an industrial waste, was used for cellulose extraction. The extraction of cellulose microfibres from hemp biomass was conducted by alkaline treatment and an acidification process. The extracted cellulose microfibres were characterised using Fourier-transformed infrared spectroscopy (FTIR), Scanning el...

Automatic Guidance of Mechanically Generated Proofs

The objectives of the project, as stated in the original proposal, were to couple the HOL and CL a M systems and to test this combination on industrially signi-cant veriication problems, to use CL a M to automate signiicant parts of HOL's proof process and to signiicantly reduce the amount of time and to simplify the interaction that it takes a HOL user to verify a system. CL a M aspects of the...

Mechanically generated surface chirality at the nanoscale.

A substrate coated with an achiral polyimide alignment layer was scribed bidirectionally with the stylus of an atomic force microscope to create an easy axis for liquid crystal orientation. The resulting noncentrosymmetric topography resulted in a chiral surface that manifests itself at the molecular level. To show this unambiguously, a planar-aligned negative dielectric aniostropy achiral nema...
