Sleeving nanocelluloses by admicellar polymerization.
نویسندگان
چکیده
This investigation reports the first application of admicellar polymerization to cellulose nanofibers in the form of bacterial cellulose, microfibrillated cellulose, and cellulose nanowhiskers using styrene and ethyl acrylate. The success of this physical sleeving was assessed by SEM, FTIR, and contact angle measurements, providing an original and simple approach to the modification of cellulose nanofibers in their pristine aqueous environment.

Stain Resistance of Cotton Fabrics before and after Finishing with Admicellar Polymerization
Environmental concerns related to perfluoroctanoic acid (PFOA) led to a re-examination of the methods for imparting stain resistance and stain repellency to textiles. Non-PFOA fluoropolymer finishes have been formed on cotton knits by admicellar polymerization, a surface analogue of emulsion polymerization. Fabric samples were characterized by a drop test, contact angle measurements, SEM, eleme...
متن کاملGrafting of Polycaprolactone on Oxidized Nanocelluloses by Click Chemistry
The main objective of this work is the grafting of polycaprolactone diol (PCL) on the surface of oxidized nanocelluloses (ONC) in order to enhance the compatibility between the hydrophilic cellulose nanofibres and the hydrophobic polymer matrix. This grafting was successfully realized with a new strategy known as click chemistry. In this context, the oxidized nanocelluloses bearing alkyl groups...

متن کاملSurface Modification of Nanocellulose towards Composite Applications
The desire to develop high-value end-products derived from renewable resources is continuously growing as a result of environmental awareness and the depletion of fossil resources. In this context, nanocelluloses have gained great interest during recent decades owing to their renewability, abundancy and remarkable physical and mechanical properties. The aim of the present work was to investigat...
متن کاملAlumina and admicellar sorbents for the separation of copper(II) ions and humic complexes in water.
alumina 1,2 or hydrated iron(III) oxide, 3 are called admicelles, whose interior tends to incorporate sparingly soluble organic constituents. Previously, we proposed a novel separation technique with admicellar sorbents for inorganic trace analysis. 4,5 For example, trace heavy metals in water were converted into hydrophobic chelates with ammonium pyrrolidinedithiocarbamate (APDC), and successf...
