Summary
Menthol-based hydrophobic eutectic solvents (HESs) offer a sustainable alternative to conventional plasticizers in biobased acrylic films. These green plasticizers enhance material properties for applications like therapeutic patches.
Area of Science:
- Polymer Science
- Green Chemistry
- Materials Science
Background:
- Conventional plasticizers in acrylic polymers raise environmental and health concerns due to volatile organic compounds (VOCs).
- The polymer industry seeks sustainable alternatives to oil-based monomers and toxic additives.
Purpose of the Study:
- To investigate menthol-based hydrophobic eutectic solvents (HESs) as eco-friendly plasticizers for biobased acrylic polymers.
- To evaluate the performance of these biobased films, particularly for therapeutic patch applications.
Main Methods:
- Synthesis of acrylic films using biobased isobornyl methacrylate (IBOMA) and 2-octyl methacrylate (2-OMA) via miniemulsion polymerization.
- Incorporation of menthol-based HESs as plasticizers.
- Comprehensive characterization of film properties (chemical, thermal, adhesive, mechanical).
Main Results:
- Menthol-based HESs demonstrated effective plasticization of biobased acrylic films.
- Plasticizer efficacy was tunable by controlling the polarity of the hydrogen bond donor and vapor pressure within the eutectic mixture.
- Biobased films exhibited suitable properties for potential use as therapeutic patches.
Conclusions:
- Menthol-based HESs are viable, multifunctional, and sustainable plasticizers for advanced acrylic materials.
- This research paves the way for environmentally friendly alternatives in the polymer industry.

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

01:20Types of Step-Growth Polymers: Polyesters
2.5K
The introduction of polyesters has brought major development to the textile industry. The wrinkle-free behavior of polyester blends has eliminated the need for starching and ironing clothes.
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...

01:20Anionic Chain-Growth Polymerization: Overview
2.5K
The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...

311
Superplasticizers are advanced admixtures that enhance the workability of concrete by lowering the water content without compromising the strength of the material. These substances are highly effective water reducers, improving concrete flow, making it easier to work with, and enabling concrete to reach inaccessible areas or densely reinforced sections without mechanical vibration. The key components in superplasticizers are either sulfonated melamine or naphthalene formaldehyde condensates,...

3.1K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...
