This review covers the recent developments in field of biobased packaging materials. Special emphasis is placed on barrier properties, which are crucial terms food packaging. The state-of-the-art several biopolymers including pectin, starch, chitosan, xylan, galactoglucomannan, lignin and cellulose nanofibrils discussed. As most cases related properties single layer biopolymer films inadequate, thin film coatings, such as sol-gel ALD (atomic deposition), well multilayer coatings also briefly touched.
Complete dissolution of cellulosic waste material in a superbase-derived ionic liquid allows for the production textile products.
Abstract In this study an optical cellulose fiber for water sensoring was prepared by using a sequential preparation strategy. The core of the from dissolved cellulose, in [EMIM]OAc, which dry–wet spun into water. cladding layer on produced coating acetate, acetone, filament coater. chemical and properties both regenerated acetate were studied cast films ultraviolet–visible Fourier-transform infrared spectroscopy measurements. Regenerated film observed to absorb UV light, passing visible...
In this study, we investigated the enzymatical degradability and pilot-scale composting of 14 cellulose-based materials. The materials analyzed here were cellulose regenerated from ionic liquid (EMIM[OAc]), carboxymethyl (CMC) crosslinked by aluminum salt (Al-salt), methyl cellulose, acetate, butylated hemicellulose: DS: 1, 0.4, 0.2, cellophane, wet strength paper, nanocellulose, paper partially dissolved IL, carbamate, palmitate, octanoate. aim study was to show how chemical substituting...

Electrospinning utilizes electric forces and hence the electrical properties of solution have an effect process.The study examined conductive additive filler on electrospinning process with polyacrylonitrile (PAN).Electrospinning trials were performed using a pure PAN solution, salt-containing containing carbon nanotubes (CNTs).Different nozzle sizes used, spinning voltage distance also varied.The composition had greater fibre diameter than varying parameters.Conductivity increased...
Abstract Electrospinning of several polyamides, PA6, PA66, PA612, PA614, PA1012, and PA1014, having different chain compositions lengths diacid diamine segments, was demonstrated. Electrospinnability fiber production rate these polyamides were evaluated. Electrospun fibers characterized with regard to their use in air filtration by measuring diameter efficiency coating. Longer nonpolar segments higher could theory indicate dielectricity compared PA6 which would be an advantage applications....
ABSTRACT A single biopolymer film rarely has a competitive edge against synthetic films. One solution is to combine several layers with different properties into multilayer structures. In this way, for example, the barrier of bio‐based materials can be improved. study, films are produced by combining three techniques/materials: 1) dispersion coating (cellulose nanofibrils, CNF), 2) atomic layer deposition (Al 2 O 3 ; aluminum oxide), and 3) extrusion (polyglycolic acid, PGA). Especially CNF...
ABSTRACT The aim of this study was to evaluate a thin, TEMPO‐oxidized (2,2,6,6‐tetramethylpiperidine‐1‐oxyl–mediated oxidation) cellulose nanofibril (CNF) coating as barrier layer in multilayer packaging films together with biobased polyethylenes. purpose also explore the possible interactions between food products and films, feasibility these for dry foods. CNF provided an oxygen suitable both demanding modified atmosphere (MAP). MAP pouches made retained their shape protected ground...
Polystyrene-block-poly(4-vinylpyridine) with nominally one pentadecylphenol molecule hydrogen-bonded to each pyridine group has been electrospun, leading fibers a hierarchical, structure-within-structure morphology (see Figure). An internal structure on the nanometer length scale exists within tens-of-nanometers scale. Internal porosity can be obtained by selective removal of amphiphile.
