“…Therefore other thermoplastic biodegradable materials, mostly polyesters-prepared microbially or chemically-have become the focus of attention in recent years. [14][15][16] Microbially Synthesized Polyester Poly(3-hydroxybutyrate) (PHB) is produced by various bacteria by fermentation of carbohydrates under controlled nutrition conditions. Similar to the function of starch or glycogen in other organisms, it serves as an energy-storage reservoir.…”

Nature or Petrochemistry?—Biologically Degradable Materials

Naturally occurring polymers have been utilized for a long time as materials, however, their application as plastics has been restricted because of their limited thermoplastic processability. Recently, the microbial synthesis of polyesters directly from carbohydrate sources has attracted considerable attention. The industrial‐scale production of poly(lactic acid) from lactic acid generated by fermentation now provides a renewable resources‐based polyester as a commodity plastic for the first time. The biodegradability of a given material is independent of its origin, and biodegradable plastics can equally well be prepared from fossil fuel feedstocks. A consideration of the overall carbon dioxide emissions and consumption of non‐renewable resources over the entire life‐cycle of a product is not necessarily favorable for plastics based on renewable resources with current technology—in addition to the feedstocks for the synthesis of the polymer materials, the feedstock for generation of the overall energy required for production and processing is decisive.

“…Renewable resources can constitute an attractive alternative to conventional petrochemical resources [1][2][3]. Thus, recent work on resins derived from natural products has led to the development of rigid foams based on polyflavonoid tannins-furfuryl alcohol copolymerization, giving foams of excellent performance and characteristics [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Mixed phenolic-polyurethane-type rigid foams were developed using tannin-furfuryl alcohol natural materials co-reacted with polymeric isocyanate in the proportions imposed by the limitations inherent to continuous industrial plants for polyurethane foams. A variety of different copolymerization oligomers formed. Urethanes appeared to have been formed with two flavonoid tannin sites, mainly at the flavonoid hydroxyl group at C3, but also, although less, on the phenolic hydroxyl groups of the flavonoid oligomers. Urethanes are also formed with (i) glyoxal in the formulation, be it pre-reacted or not with the tannin; (ii) with phenolsulfonic acid and (iii) with furfural. This latter one, however, greatly favors reaction with the A-ring of the flavonoids through OPEN ACCESSPolymers 2014, 6 2986 a methylene bridge rather than reaction with the isocyanate groups to form urethanes. All of the materials appeared to have co-reacted in a manner to form urethane and methylene bridges between all of the main components used. Thus, the tannin, the furfuryl alcohol, the isocyanate, the glyoxal and even the phenol sulfonic acid hardener formed a number of mixed species linked by the two bridge types. Several mixed species comprised of 2, 3 and even 4 co-reacted different components have been observed.

“…Polymers from renewable resources are now considered as promising alternatives to petroleum-based polymers as they meet current environmental concerns in terms of environmental pollution, greenhouse gas emissions and the depletion of fossil fuel resources [6][7][8]. Poly(lactic acid) (PLA) is aliphatic polyester derived from the fermentation of renewable agricultural crops, such as, corn, potato, rice, sugar beet and other agriculture products [9,10].…”

The aims of the present study were to use organoclay to improve the property of poly(lactic acid) (PLA) fiber in the dyeing process. Chitosans were used to modify montmorillonite (MMT) to produce organoclay. Poly(lactic acid) was melt-mixed with oganoclay using a twin-screw extruder to achieve a PLA/organoclay nanocomposite. The nanocomposite fiber was then prepared using single-screw extruder. The effects of organoclay on the structure, thermal and dyeing properties of the nanocomposite were also investigated. The results of dyeing show that the nanocomposite fiber was dyeable with natural dye extracted from curcumin. The colour strength was found to be dependent on the amounts of chitosan in the organoclay. The fastness properties such as wash fastness and light fastness were found to be similar to that in traditional fibers. Other properties such as thermal stability were also reported. This study demonstrates that poly(lactic acid) can exhibit natural dyeability through its preparation in nanocomposite form.
