Biodegradable Polymer
We have developed biopolymer nanoparticle technology based on cost-effective biodegradable and biocompatible polyolefins and copolymer of ethylene and vinyl acetate and thermoplastic starch (TPS) blend nanocomposites wherein these nanocomposites of the present invention have improved mechanical, zero moisture content and biodegradable properties.
Modern-day technology calls for the development of ecofriendly polymeric materials having the desirable mechanical properties. The effects of environmental factors (e.g. water, atmospheric oxygen, sunlight and biological agents, such as microbes, fungi, insects, etc.) alter the service life of many articles prepared from polymeric materials. However, the immense bulk of polymeric materials and articles made thereof put forward a problem of their further destruction or disposal after the termination of their service life. Many polymers are decomposed in the environment over a relatively long period of time; therefore, the production of biodegradable materials is as important area of research.
Polymers, particularly house-hold plastics and films, must be rapidly decomposed after use under the influence of chemical (atmospheric oxygen, water), physical (sunlight, heat) and biological (bacteria, fungi, yeasts, insects, etc.) environmental factors. These factors produce a synergistic effect, eventually resulting in the fragmentation of the polymer owing to the destruction of its macromolecules and their conversion into low molecular weight compounds that can be further involved in the natural circulation of substances.
Because of the rising consciousness on the environmental protection, the development of various biodegradable polymers has received much attention by the industry in recent years, especially the biodegradable polymers applied in the packaging industry. However, the price of biodegradable polymers is usually quite high, and the mechanical properties such as tensile strength, tearing resistance etc are inferior to the conventional packaging materials, such as polyethylene (PE).
Therefore, a blending process is required for the preparation of a biodegradable polymer to be commercialized successfully. In particular, the starch-based biodegradable polymers are widely studied due to the relatively low price of raw starch materials. However, there are some disadvantages associated with them like moisture sensitivity problem, which in turn may affect their mechanical properties by some parameters. So there is a need to better understand this behaviour. Our new invented technology overcomes all these above mentioned deficiency.
Hybrid composites made of natural fibers with metal matrix and thermoset resins
This newly developed hybrid composites material that consists of jute fiber fabric and aluminum sheeting, with an epoxy resin modified with resol type phenol formaldehyde (PF) offering high modulus, along with high tensile strength in the longitudinal direction, and good thermal stability with low water uptake, these hybrid materials have potential applications in the aerospace and automotive industries, as well as for use in high performance end products. It has low cost and high mechanical properties.
Recycling of XLPE waste
We have developed this path breaking technology. XLPE is a competitor sheeting materials for PVC, used as for electric power cable sheathing and telecommunications cables as well as insulation for electric wires and cables where PVC is easily recyclable but due to XLPE’s cross linking nature it is not like that.
XLPE is a material in which the polyethylene molecule chains have been crosslinked by such means as organic peroxides, ionizing radiation or silane compounds. It is virtually impossible to reuse XLPE in the same application. There are some techniques such as pyrolysis and pulverization that have been used in the past to recycle XLPE that was not environmental friendly and totally recyclable.
We have developed unique techniques to recycle XLPE waste and solve down land filling, green house gas emissions and others.
