“…Effect of silane coupling agent and soft monomer on the properties of latex and its film At present, KH-570 has been the most studied for its application in nanomaterials, and it was mainly used to modify the surface of nano-SiO 2 , and examples of its use in modifying acrylic polymer emulsions were relatively rare (Hou et al, 2014;Ye et al, 2013). Through the experiment, it was found that the introduction of KH-570 has resulted in an important effect on the hardness and tensile strength of latex.…”

Purpose Silane cross-linkers have been used to strengthen the mechanical stabilities and friction resistance of plastic products. Therefore, the effect of silane cross-linkers on latex has been studied through preparing modified self-cross-linking long fluorocarbon polyacrylate latex. In this paper, nonionic surfactant alcohol ether glycoside (AEG1000) and anionic polymerizable surfactant 1-allyloxy-3-(4-nonylphenol)-2-propanol polyoxyethylene (10) ether ammonium sulfate (DNS-86) acted as mixed emulsifier and 3-(methacryloyloxy) propyltrimethoxysilane (KH-570) and bis (2-ethylhexyl) maleate (DOM) were used as functional monomers. Design/methodology/approach The modified acrylate polymer latex was synthesized through the semi-continuous seeded emulsion polymerization with methyl methacrylate (MMA), butyl acrylate (BA), dodecafluoroheptyl methacrylate (DFMA) and hydroxypropyl methacrylate (HPMA) as main monomers. Potassium persulfate (KPS) was applied to initiate polymerization reaction, nonionic surfactant AEG1000 and DNS-86 acted as emulsifier, KH-570 and DOM were used as functional monomers, respectively. Findings The optimum conditions of synthesizing the modified latex were the following. The mass ratio of monomers containing MMA, BA, DFMA, HPMA, KH-570 and DOM was 13.58:13.58:0.90:1.20:0.15:0.60, the usage of initiator KPS was 0.5% of the total weight of monomers and the amount of emulsifier was 7% of all monomers with AEG1000:DNS-86 = 1:1. The results indicated that the conversion of monomer was 99% and the coagulation was about 2.0%. Originality/value The resultant latex was modified silane cross-linker KH-570 and DOM, which positively affected the comprehensive properties of latex and its film. Apart from this, the novel mixed emulsifier was used to improve the size and distribution of latex particles and reduce environmental problems caused by the use of emulsifiers.

A novel kind of bifunctional nanoencapsulated phase change material with thermal energy storage and ultraviolet absorption functions was successfully prepared through surfactant‐free emulsion polymerization with reactive emulsifiers. These nanocapsules consisted of n‐octadecane and n‐butyl stearate as binary core materials and polyacrylate supplemented with titanium dioxide nanoparticles (nano‐TiO2) as hybrid shell materials. The experimental results show that the monomer conversion and thermal conductivity increased and the particle size and distribution decreased with increase in nano‐TiO2 content when the nano‐TiO2 dosage was below 0.2 wt%. Fourier transform infrared spectroscopy and XRD confirmed that the binary phase change materials were well encapsulated inside the polyacrylate‐TiO2 hybrid shell and nano‐TiO2 was also successfully crosslinked in the nanocapsules. TEM demonstrated that the synthesized nanocapsules exhibited a regular spherical profile and a well‐defined core–shell structure with diameter ranging from 70 to 100 nm. In addition, the results obtained from DSC, TGA and UV–visible spectrophotometry showed that the as‐prepared nanocapsules had good thermal storage capacity, thermal stability and ultraviolet absorption properties. It can be considered that the resultant nanoencapsulated phase change materials with polyacrylate‐TiO2 hybrid shell may have high feasibility and hold good promise in the applications of intelligent thermoregulation fabrics. © 2019 Society of Chemical Industry
