“…The substitution of these compounds by less hazardous ones such as triethyl citrate, tributyl citrate, tributyl 2‐acetyl citrate, triacetin, tripropionin, and low molecular weights PEO have been largely studied. These plasticizers increase the weight loss of the materials and decrease the Tg of cellulose acetate.…”

Polymeric materials, in particular PVC, can find various industrial utilizations thanks to the use of plasticizers added during their processing. The most famous applications include wires and cables, coatings, flooring, paintings, packaging… After some generalities concerning plasticization theories and the description of plasticized petro‐ and bio‐based polymers, this review details the well‐known different petro‐based plasticizers and more particularly phthalates which represent the most important category of PVC plasticizers. Owing to migration problems, impact on the human health and the environment, alternative candidates have been developed by researchers. Renewable resources and their wastes offer a large platform for the design of bio‐based plasticizers using polysaccharidic or lipidic structures. In an in‐depth analysis, the bio‐based plasticizer structures, their groups and substituents (ester groups, alkyl chains, aromatic rings…) are gathered and examined in order to be able to predict their plasticizing efficiency and design new molecular and macromolecular plasticizers from natural resources. © 2015 Wiley Periodicals, Inc.

“…The crystallinity of the aged blends was higher than that of the unaged blends. This is because SSP easily diminished after exposure to aging [25]. The amorphous regions were degraded due to the heat of the surroundings, whereas the crystalline regions remained unaffected.…”

This study investigates the properties of highdensity polyethylene (HDPE) with different soya spent powder (SSP) blend contents upon oven aging. The aged properties of the HDPE/SSP blends were studied by using tensile test, thermogravimetric analysis, differential scanning calorimetry and Fourier transform infrared analysis. The tensile strength and elongation at break (E b ) decreased inversely proportional to SSP content and aging period. The thermal stability of the blends was significantly reduced after 21 days of aging. After aging, the melting temperature and crystallinity of the blends decreased with increasing aging period. These results revealed that samples with higher SSP content are more brittle upon oven aging.

“…Another contributing factor to the deterioration is migration of plasticizer, the presence of white crystals on the surface of the substrate are observed when the plasticizer moves towards the substrate [11][12][13][14].…”

Microbubble disease observed in cellulose acetate microfilm was accompanied by the production of vinegar syndrome, which has a negative influence on the integrity of image. In the present study, cellulose acetate microfilm with microbubble disease from the Republic of China (AD 1912-1949) collected in the Second Historical Archives of China was chosen as a prototype to investigate its treatment methods. A combination of optical microscopy and a stainless-steel needle was used to remove plasticizer exudation within microbubbles. The plasticizer was effectively removed by infiltrating butan-1-ol into the microbubble from a small hole made by the stainless-steel needle. The SEM and laser confocal microscopy were used to study the morphology and roughness of the internal surface of microbubble. It was found that the blurry image could be attributed to the light scattering from the rough surface. Based on the advantages of ethyl cellulose in conservation science, the optimal concentration of ethyl cellulose was selected and used to fill the interior of the microbubble to obtain a clearer image. To determine the protective potential of this filling material, the chemical and mechanical properties of coated film after dry heat, hygrothermal and UV accelerated ageing were measured. Based on the above-mentioned results, it is encouraging that a new microrepair method and its corresponding method are offered in film treatment work.
