Biodegradable polymers by reactive blending trans-esterification of thermoplastic starch with poly (vinyl acetate) and poly (vinyl acetate-co-butyl acrylate)

Author: Vargha, V ; Truter, P Date: Apr 2005 Wheat starch was reacted with poly (vinyl acetate) and with poly (vinyl acetate-co-butyl acrylate) in an internal mixer at 150 _C in the absence of catalyst, and in the presence of sodium carbonate, zinc-acetate and titanium (IV) but oxide. ... Read more
Biodegradation of flax fiber reinforced poly lactic acid

Author: Kumar, R ; Yakubu, MK ; Anandjiwala, RD Date: Jul 2010 Woven and nonwoven flax fiber reinforced poly lactic acid (PLA) biocomposites were prepared with amphiphilic additives as accelerator for biodegradation. The prepared composites were buried in farmland soil for biodegradability studies. Loss ... Read more
Cellulose nanostructure-based biodegradable nanocomposite foams: A brief overview on the recent advancements and perspectives

Author: Motloung, Mpho P ; Ojijo, Vincent O ; Bandyopadhyay, Jayita ; Ray, Suprakash S Date: Jul 2019 The interest in designing new environmentally friendly materials has led to the development of biodegradable foams as a potential substitute to most currently used fossil fuel–derived polymer foams. Despite the possibility of developing ... Read more
Mechanical, thermal, and fire properties of biodegradable polylactide/boehmite alumina composites

Author: Das, K ; Ray, Suprakas S ; Chapple, Stephen A ; Wesley-Smith, J Date: May 2013 Boehmite alumina (BAl) was investigated in terms of its use as an filler to improve the inherent properties of polylactide (PLA). Composites of PLA with different loadings of BAl were prepared by melt-blending. Morphological analysis using ... Read more
Optimisation of ported yield of hemispherical ported microparticles for soft tissue augmentation

Author: Barnard, A ; Kotzé-Jacobs, L ; Moolman, S Date: May 2011 The use of biodegradable polymers in temporary surgical and pharmacological applications has become a prominent part of polymer research. Poly(e-caprolactone) (PCL) is widely studied for tissue engineering applications due to its relatively ... Read more
Polystyrene/TiO2 composite electrospun fibers as fillers for poly(butylene succinate-co-adipate): Structure, morphology and properties

Author: Neppalli, R ; Causin, V ; Benetti, EM ; Ray, Suprakas S ; Esposito, A ; Wanjale, S ; Birajdar, M ; Saiter, J-M ; Marigo, A Date: 2014 In this work, composite polystyrene/titanium dioxide (PS/TiO(sub2)) electrospun fibers were used as a reinforcement for a poly(butylene succinate-co-adipate) (PBSA) matrix. The structure, morphology, mechanical properties and degradation ... Read more
Processing strategies in bionanocomposites

Author: Ojijo, Vincent O ; Ray, Suprakas S Date: Oct 2013 In recent years, the development of environmentally friendly polymeric materials, which are primarily based on biodegradable polymers (from both fossil-fuel and natural resources) with balanced properties, has become the focus of considerable ...

Role of special interfacial area in controlling properties of immiscible blends of biodegradable polylactide and poly[(butylene succinate)-co-adipate

Author: Ojijo, Vincent O ; Ray, Suprakas S ; Sadiku, R Date: Dec 2012 Binary blends of two biodegradable polymers: polylactide (PLA), which has high modulus and strength but is brittle, and poly[(butylene succinate)-co-adipate] (PBSA), which is flexible and tough, were prepared through batch melt mixing. The ... Read more
