Preparation and characteristics of nanocapsules containing essential oil for textile application

Abstract

Methyl methacrylate (MMA)-styrene (St) copolymer nanocapsules containing cologne essential oil for fragrant fabrics treatment were prepared by miniemulsion polymerization. The morphology, chemical composition and thermal properties were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) and thermal gravimetric analysis (TGA). The nanocapsules had relatively small size (ca. 136 nm of mean particle diameter), regular sphericity and uniform particle size distribution. The encapsulation efficiency and loading capacity of the nanocapsules were 85.4% and 42.7%, respectively. The nanocapsules had good thermostability. The release experiments showed that 6.8% cologne essential oil still existed after being washed 15 times in the fabrics treated with nanocapsules, indicating that the fabrics treated with nanocapsules had good washing durability.

Core–shell nanocapsules containing essential oil for textile application

“…First, high thermal stability is need, due to long time finishing process on the cotton fabrics where the treatment temperature is normally pretty high. 22 Based on the previous work, the novel P(St-MMA)/PBA core-shell nanocapsules with much better washing durability were prepared. 13 Among materials that can be used to prepare capsules, polymers with core-shell structures are of great scientific and industrial interests because their chemical and mechanical properties can be tailored for applications easily and the versatility of monomers allows the design of nanocapsules with welldefined size distribution and release properties.…”

“…21 In our previous work, P(St-MMA) copolymer nanocapsules containing cologne essential oil for fragrant fabrics treatment were prepared by miniemulsion polymerization, with high EE and loading capacity (LC). 22 Based on the previous work, the novel P(St-MMA)/PBA core-shell nanocapsules with much better washing durability were prepared. PBA is a soft polymer with a low glass transition temperature, which is in rubbery state and polymer chains are mobile at room temperature.…”

Destruction of Opportunistic Pathogens via Polymer Nanoparticle‐Mediated Release of Plant‐Based Antimicrobial Payloads

“…In this direction, essential oils (EOs) – typically complex extracts from aromatic plants comprising mixtures of aldehydes, terpenes, and phenols – are well known to exhibit broad spectrum biological and antimicrobial activity . With many EOs identified as “Generally Regarded as Safe,” these extracts have been actively explored and continue to garner interest as food preservatives and packaging constituents, textile fragrances, pesticides, and other antimicrobial therapeutic applications …”

“…Fragrance is one of the main ingredients in food, cosmetics, pharmaceuticals, and other daily necessities. [1][2][3] Pleasant aroma always makes people happy. However, the poor stability and volatile nature of fragrance molecules have made them hard to guarantee the quality of the products.…”
