Bionanocomposite Films

Production of Polylactic acid (PLA)/Polycaprolactone (PCL) bionanocomposite films with various ratios was done by adding nanocrystalline celullose (NCC) from oil palm empty fruit bunches (OPEFB) as a filler. The aim of the research was to find out the effect of PLA/PCL ratio on film thickness, transparency of bionanocomposite films and water vapor permeability or WVP of the film bionanocomposite with addition of the 3% NCC.  The PLA/PCL ratio are 1.0/0.0; 0.8/0.2; 0.6/0.4; 0.5/0.5; 0.4/0.6; 0.2/0.8; and 0.0/1.0, prepared with solvent casting method. Characterization of PLA/PCL bionanocomposites film performed was thickness, transparency test and water vapor permeability (WVP) test. The thickness of bionanocomposites film produced were around are about 0.036-0.053 mm, results show that the lower PLA/PCL ratio the thicker film obtained. The highest value of film transparency was obtained at a ratio of 1.0 / 0.0 (81.4% at a wavelength of 550 nm), the smaller the PLA / PCL ratio, the lower the value of transparency. The WVP value of PLA/PCL bionanocomposite films gives a lower value than the WVP value of pure PLA film and pure PCL film. The best WVP was obtained at a PLA/PCL ratio of 0.8/0.2 which was 1.49x10-16kg.m/(m2.s.Pa).

Chitosan Membranes

Among the variety of polymers used as drug carriers, chitosan has received attention in the fields of medicine and pharmacy by being a nontoxic, biocompatible and biodegradable copolymer. Piperine is a natural alkaloid, has various pharmacological activities such as anti-inflammatory, analgesic, antipyretic, hepatoprotective and antitumor when combined with chitosan has better bioavailability and more effectiveness. This work aims to prepare and characterize chitosan / piperine membranes obtained by the solvent casting method. The membranes were characterized by Spectroscopy Fourier Transform Infrared (FTIR), X-ray Diffraction (DRX) and Scanning Electron Microscopy (MEV). From the results obtained it can be concluded that the process described was effective in obtaining the system chitosan/piperine indicating its potential for studies of controlled release of drug.

Solution Casting Method

Polylactic acid (PLA) based biocomposite films, reinforced with different loadings of organoclay, were prepared by solution casting method. Four different loadings of clay was done, 2, 5, 10 and 15 weight% with respect to the matrix. These biocomposite films were characterized by mechanical characterization, scanning electron microscopy (SEM) moisture diffusivity property at 93% RH. Both the mechanical and the visco-elastic property of these films were measured by nano indentation technique. Mechanical property by nano indentation analysis revealed an idea about the extent of clay dispersion in the matrix. The amount of clay loading and its dispersion significantly affected the mechanical as well as the Visco-elastic behavior of the biocomposite films. The morphology of the films were observed with the help of SEM.

To develop osmotic granule with semi-permeable membranes, we prepared the semipermeable membranes with different pore forming agent by using solvent casting method. The membrane was consisted of cellulose acetate, Eudragit® RS, hydroxypropylcellulose (HPC), and triethylcitrate (TEC) in the presence of PEG200, PEG1, 000, or dibutylsebacate(DBS) as a pore forming agent. The produced membranes were white and elastic and exhibited soft property on touch. The release amount of pore forming agent from membrane with different pore forming agent was measured in water dissolution media and the order was PEG200 > PEG1, 000 > DBS. The formation of pore in membrane was observed by morphological SEM image after dissolution. The pore formation and porosity of membrane depended on water solubility of pore forming agent. We confirmed that pores in porous semi-permeable membrane could be controlled by the pore forming agent.

Biocomposite Films

Nowadays bioplastics is the most recent study materials as the substitute for conventional plastics. The interest in bioplastics has lead to the production of polylactic acid (PLA) biocomposite films. In this study the PLA/Corn husk (CH) biocomposite films were prepared by using solvent casting method and the effect of CH content on the tensile properties were studied. The result found that increasing of CH content decreased the tensile strength and elongation at break of the biocomposites film. While, the modulus of elasticity increased with the increasing of CH content in the PLA matrix.
