Abstract
Tourmaline was modified with vinyl triethoxysilane containing double bond to prepare the polymerizable organic vinylsiliconoxyl tourmaline (VST) and then copolymerized with methyl methacrylate (MMA) and butyl acrylate (BA) to produce the tourmaline-containing functional copolymer p (VST/MMA/BA). The structures and morphologies of VST and p (VST/MMA/BA) copolymer were characterized by IR, SEM, and EDX. The experimental results indicated that tourmaline was introduced into the copolymer via surface modification and the tourmaline-containing functional copolymer was obtained by a copolymerization process with MMA and BA. The prepared p (VST/MMA/BA) copolymer displayed excellent storage stabilities, high far-infrared radiation and negative ion releasing performances, and good mechanical properties.
Highlights
Negative oxygen ions possess the efficacy of promoting metabolism of the human body, being able to prevent influenza, enhance human immune system, and restore the balance of the human body [1]
20 mL of mixture of butyl acrylate (BA) and methyl methacrylate (MMA) (1 : 1) dissolved in Benzoyl peroxide (BPO) was added to the flask with stir via the constant pressure funnel under 70°C. 2 g polymerizable organic vinylsiliconoxyl tourmaline (VST) was added into the flask while the viscosity started to rise and the reaction lasted for 9 h at 70°C under stirring to obtain the tourmaline-containing functional copolymer p (VST/MMA/BA)
The FTIR results confirmed that vinylsiliconoxyl was introduced onto the surface of tourmaline to produce the polymerizable organic VST via surface modification (Scheme 1)
Summary
Negative oxygen ions possess the efficacy of promoting metabolism of the human body, being able to prevent influenza, enhance human immune system, and restore the balance of the human body [1]. Because of its special chemical structure, it possesses many unique physical and chemical properties [6], such as far-infrared radiation [7, 8] and negative ion release [9, 10]. We prepared the tourmaline-containing functional copolymer p (TUC/BA/ MMA), which displayed an excellent storage stability, excellent mechanical properties, superior performance in farinfrared radiation, and enhanced negative ion release [21]. We developed a new method to prepare tourmaline-containing functional copolymer. The structures and morphologies of VST and copolymer p (VST/MMA/BA) were characterized by IR, SEM, and EDX, and their mechanical properties and performances in far-infrared radiation and negative ion release were evaluated quantitatively
