Abstract To obtain high performance of nanocomposite films made of cellulose nanofibrils (CNFs) and montmorillonites (MMTs), highly ordered nanostructures and abundant interfacial interactions are of extreme importance, especially for CNF film with high MMT content. Here, we tend to unveil the influence of exfoliation degree of MMTs and their interfacial interactions with CNFs on the properties of ensuing nanocomposite films. Monolayer MMTs prefer to form highly ordered nanostructure during water evaporation induced self-assembly. The obtained nanocomposite film with 30 wt% monolayer MMTs exhibits a tensile strength of 132 MPa, a total light transmittance of 90.2% (550nm), and water vapor transmission rate (WVTR) of 41.5 g•mm/m2•day, better than the film made of original bulk MMTs and CNFs (30 MPa strength, 60% transparency, and 78.7 g•mm/m2•day WVTR). Moreover, the physical properties (153 MPa strength and 20.9 g•mm/m2•day WVTR) of nanocomposite film can be further enhanced by constructing ionic interactions between the monolayer MMT and CNF using 0.5 wt% cationic polyethylenimine (PEI). However, as the amount of PEI continues to increase, its performance will be deteriorated dramatically because of the disordered orientation of monolayer MMTs. This work could provide an insight into the fabrication of high performance MMT/CNF nanocomposite film for advanced applications.

In this present work, chitosan (CS) crosslink with polyaniline (PANI) with montmorilonite (MMT) called as (CSPANI/MMT) and CS crosslink with PANI without MMT called as (CS-PANI) were prepared by employing the solution casting method. Further the formation of nanocomposites CS-PANI/MMT and CS-PANI were investigated using XRD, FTIR, SEM and tensile strength. Water uptake and swelling ratio of the CS-PANI and CS-PANI/MMT were found to decrease with increase in concentration of clay. Mechanical properties of the CS-PANI and CS-PANI/MMT were assessed in terms of tensile strength and extensibility using texture analyzer. Increase in tensile strength and reduction in extensibility was reported with increase in the nanoclay content. In vitro drug release study on CS-PANI and CS-PANI/MMT indicated pronounced sustained release of doxorubicin by the incorporation of clay particles in the CS polymer matrix. Overall CSPANI/MMT nanocomposite films exhibited improved mechanical and sustained drug release properties than CS-PANI.

Nanocomposites are substances that incorporate nanoparticles (0.5-5% by weight) into a matrix of standard material, which enhances the mechanical strength, toughness including thermal or electrical conductivity and other properties. Nanocomposites are versatile in terms of their applications such as anti-corrosive, healing of bones, sensors, environmental protection, packaging, wastewater treatment, and diagnosis of tumors and other diverse uses. They may be fabricated by blending nanofillers with a polymer to produce a composite. The current trend of processing is by polymerizing monomers. Nanocomposites serve as sustainable solutions to curb global issues. Evaluation is performed on properties such as mechanical, thermal, dispersion, and toxicological. Some marketed products of nanocomposites include In Mat (coating), FiltekZ350 XT by 3M (tooth fillers), chitosan/organic rectorite nanocomposite films (bactericidal activity), graphene oxide/Carboxymethylcellulose (targeted drug delivery of anti-cancer drug doxorubicin), MD1 Flex, Nano Clean MD1, Plactive TM (Antimicrobial nanocomposites) and NovaProTM(Tooth fillers). This article discusses about Nanocomposites–their types, preparation methods, recent research and applications.
