Title: A Review on Plasticizers and Eco-Friendly
Bioplasticizers such as epoxidized plant oils, cardanol, citrates and Isorbide esters are derived from further modifications of oils and triglyceride, starch and cellulose, citric acids and...
Natural-based plasticizers and biopolymer films: A review
Industrially, the most common plasticized polymers are PVC, poly (vinyl butyral) (PVB), poly (vinyl acetate) (PVAc), acrylics, cellulose molding compounds, nylon, polyamides and certain copolyamides. PVC processing is by far the most important use of plasticizers, consuming over 80% of production [3], [4].
Interfacial effects of plasticizers on the properties
Cellulose diacetate (CDA) is a biodegradable biobased polymer, which is not easily melt-processable with a narrow window between flowing and decomposition temperature. Selecting the appropriate plasticizer and evaluating its effect on the properties are important for the application developments of CDA materials. In this paper, eco-friendly plasticizers, such as glycerin (GL), diacetin (DA
Cellulose Acetate Thermoplastics with High Modulus
Cellulose diacetate (CDA) can be melt-processed to produce numerous and widely-used plastic products. However, due to the high glass transition temperature (Tg) of CDA, the addition of up to 30 wt% of micromolecular plasticizers is indispensable, which significantly reduces the dimensional stability and raises safety concerns from the migration of plasticizers. In this work, a series of CDA
Brazil: The circular economy is a boost for the cellulose
Following the signature of a contract based on circular economy principles in 2011, Veolia and Fibria have become global benchmarks in the management of waste from the paper pulp (cellulose) industries. The operator is responsible for converting 100% of the mineral waste generated during Fibria’s cellulose production process, at both its
- What are plastics based on cellulose?
- This chapter is concerned with plastics based on cellulose, produced from either cotton linters or wood pulp. They have the advantage of being produced from a renewable source. Cellulose itself is both crystalline and hydrogen bonded, so is insoluble and cannot be melted.
- Can plasticizers be used in regenerated cellulose films?
- This challenge may restrict their application in electronic devices like optoelectronics, including solar cells and touch screens [20, 21]. Additionally, incorporating plasticizers into regenerated cellulose films can increase or decrease the transmittance of these films .
- Does incorporating plasticizer reduce cellulose decomposition temperature?
- Thus, incorporating plasticizer also reduced all films' initial and final decomposition temperature, possibly due to the mixing and interactions of the regenerated cellulose with the plasticizers . Incorporating AgNP in all nanocomposite films shifted the cellulose degradation peak to lower temperatures.
- Can glycerol be used as a plasticizer in packaging film production?
- Tensile strengths of 10 to 30 MPa and percentages of elongation at break of 3 to 60% were obtained with 20 to 30% glycerol as a plasticizer in packaging film production with starch biopolymers [86, 87]. Cellulose is an extract from plants and is the most abundant material on earth.
- Does plasticizer and AgNP incorporation affect the transmittance of regenerated cellulose films?
- Therefore, UV-Vis investigated the effect of plasticizer and AgNP incorporation on the transmittance of regenerated cellulose films. The UV-Vis results and the transmittance values for the films at 550 nm are presented in Figure 3. The transmittance curve for all RCF films was observed throughout the wavelength range between 200 and 800 nm .
- Are natural polymers a viable alternative to plastics?
- Natural polymers such as cellulose, starch, chitosan, and protein extracted from renewable resources are extensively explored as alternatives to plastics due to their biodegradability, biocompatibility, nontoxic properties, and abundant availability.
