Using a method of combined HNO(3)-KClO(3) treatment and sulfuric acid hydrolysis, bamboo cellulose crystals (BCCs) were prepared and used to reinforce glycerol plasticized starch. The structure and morphology of BCCs were investigated using X-ray diffraction, electron microscopy, and solid-state (13)C NMR. Results showed that BCCs were of typical cellulose I structure, and the morphology was de...

F1-antigen purified from Yersinia pestis was covalently linked to 5-mm diameter filter paper discs plasticized with polyvinyl alcohol-glutaraldehyde. These discs were used both for ELISA and dot-ELISA for the detection of anti-F1 IgG in rabbits. The best conditions were achieved using 1.25 microg of F1 antigen/disc, 3% w/v skim milk in PBS as blocking agent, anti-IgG peroxidase conjugate dilute...

In this research an attempt is made to modify the brittle poly (Lactic acid) (PLA) into flexible PLA by adding Poly (Butylene Succinate) (PBS), Poly (Ethylene Glycol) (PEG) and Ricinoleic acid (R.ACID) as a plasticizer. Various plasticizers with different weight % of plasticizers 10%, 20% and 30% in wt% for PLA/PBS, 5, 10 and 15% for PLA/PEG and PLA/R.ACID are used to make sheets. With the addi...

Malaysia, especially the Borneo Island state of Sarawak, has a large variety of tropical wood species. In this study, selected raw tropical wood species namely Artocarpus Elasticus, Artocarpus Rigidus, Xylopia spp., Koompassia Malaccensis, and Eugenia spp. were chemically treated with sodium metaperiodate to convert them into plasticized wood (PW). Manufactured plasticized wood samples were cha...

Two types of externally plasticized cellulose acetate (CA) were chemically modified using 4,4'-methylene diphenyl diisocyanate (MDI) as crosslinking agent. Crosslinking was performed in the molten state by means of melt mixing in an internal mixer. The viscoelastic properties of the non-crosslinked, externally plasticized CA show typical temperature dependence, similar to conventional thermopla...

Soft denture-lining materials are an important treatment option for patients who have chronic soreness associated with dental prostheses. Three distinctly different types of materials are generally used. These are plasticized polymers or copolymers, silicones, or polyphosphazene fluoroelastomer. The acceptance of these materials by patients and dentists is variable. The objective of this study ...

A renewable resource, epoxidized jatropha oil (EJO), was used as a green plasticizer and added to poly(lactic acid) (PLA). EJO was compounded into PLA at different contents. The addition of 3 wt % EJO to the PLA demonstrates significant improvement in flexibility, which leads to a percentage increase of about 7000% in elongation at break. This tensile result was confirmed by surface morphology ...

Identifying the parameters that can impact sorption of drugs to polymer materials is critical design medical devices which would prevent drug loss by sorption. We propose a combined approach based on advanced molecular simulations and liquid chromatography experiments investigate adsorption active pharmaceutical ingredients (API) onto plasticized PVC materials. The thermodynamic characterizatio...

Abstract A polyester plasticizer (RSOP) for polyvinyl chloride based on rubber seed oil (RSO) was synthesized. Firstly, RSO monoglyceride were synthesized by the transesterification of with glycerol at 220–240 °C. Secondly, RSOP from and adipic acid esterification. The characterized GPC, FT-IR, 1 H NMR DSC. Plasticized (PVC) materials dioctyl phthalate (DOP) in varying ratios prepared via therm...
