Materials based on biodegradable polyesters, such as poly(butylene terephthalate) (PBT) or poly(butylene terephthalate-co-poly(alkylene glycol) terephthalate) (PBTAT), have potential application as pro-regenerative scaffolds for bone tissue engineering. Herein, the preparation of films composed of PBT or PBTAT and an engineered spider silk protein, (eADF4(C16)), that displays multiple carboxyli...

In this study, a kind of biodegradable material was developed by blending polylactide (PLA) with natural biodegradable dextran, and a novel sponge-like scaffold made of it was fabricated thereof using solvent-casting and particle-leaching technique. To obtain a uniform blend of PLA and dextran by simple solvent-casting method, hydroxyls of dextran should be protected via trimethylsilyl (TMS) gr...

A novel Starch/Poly (vinyl alcohol)/nano-Titanium dioxide (ST/PVA/nano-TiO2) biodegradable nanocomposite film was prepared by homogeneously dispersed TiO2 nanoparticles in different ratios of starch/PVA-based materials, via a solution casting method. Glycerol was used as plasticizer. The mechanical and thermal properties of films were studied using tensile and perforation strength tests and the...

The non-biodegradable nature of plastic packaging has brought about an attention in bio-basedpackaging materials. Edible composite films were prepared using soy protein concentrate (SPC) and pullulan(PUL) biopolymer at five different ratio (100:0; 70:30; 50:50; 30:70 and 0:100) with glycerol as plasticizer bycasting-evaporation method. The thickness, mechanical properties, water vapor permeabil...

The peculiarities of the technology hybrid modification lignite humic acids biodegradable films based on hydroxypropylmethylcellulose are considered. As a result conducted research, with antibacterial properties were obtained for first time. Hydroxypropylmethylcellulose Walocel brand was used production films, and citric acid (99.88%) according to GOST 3652 is as catalyst crosslinking polymer f...

Correction for ‘ In vivo wound healing efficiency of curcumin-incorporated pectin-chitosan biodegradable films’ by V. Muthulakshmi et al. , New J. Chem. 2021, DOI: 10.1039/d1nj03477d.

the usage of antimicrobial materials for coating meat products, in addition to reducing the microbial population and increase of the quality safety of products, be greatly reduced usage of nitrites as preservatives and synthetic carcinogens. compounds that have antimicrobial activity can be mixed, stabilized or incorporated with edible coatings. spices and vegetable extracts are also a group of...

Corn starch-based films are inherently brittle and lack the necessary mechanical integrity for conventional packaging. However, the incorporation of additives can potentially improve the mechanical properties and processability of starch films. In this work two essential oils, Zataria multiflora Boiss (ZEO) or Mentha pulegium (MEO) at three levels (1%, 2% and 3% (v/v)), were incorporated into s...

Electrostatic self-assembly was used to fabricate new smart multi-layer coatings, using a recombinant elastin-like polymer (ELP) and chitosan as the counterion macromolecule. The ELP was bioproduced, purified and its purity and expected molecular weight were assessed. Aggregate size measurements, obtained by light scattering of dissolved ELP, were performed as a function of temperature and pH t...
