  • Glass surface modification via Cu(0)-mediated living radical polymerization of fluorinated and non-fluorinated acrylates
Title: Glass surface modification via Cu(0)-mediated living radical polymerization of fluorinated and non-fluorinated acrylates
Terminal silanol groups on the glass surface were used for the chemical bonding of α-bromo amide as the initiator for surface initiated Cu(0)-mediated living radical polymerization (LRP) to graft well-defined poly(butyl arylate) (PBA) and poly(2,2,2-trifluoroethyl methacrylate) (PTFEM) brushes on the glass surface. A grafting to methodology was also performed by the modification of the glass surface using a thiosilane agent and performing a thio-bromo click reaction in the presence of PBA and PTFEM synthesized via Cu(0)-mediated LRP. Furthermore, a one-pot grafting to method was developed that proved a facile, fast, and efficient method for grafting a bromo-terminated polymer to the glass surface in one step. All glass slides were characterized using ATR-FTIR and UV-vis spectroscopy, water contact angle measurements and SEM. The surface topology and roughness of selected samples were analyzed using AFM. Results show that an ultrathin layer of a polymer with nanoscale features and high roughness was chemically grafted to the glass surface without compromising glass transparency. These methodologies can be used to graft well-defined polymers with different functionalities on the glass surface.  more » « less

    We report a green solvent-to-polymer upgrading transformation of chemicals of the lactic acid portfolio into water-soluble lower critical solution temperature (LCST)-type acrylic polymers. Aqueous Cu(0)-mediated living radical polymerization (SET-LRP) was utilized for the rapid synthesis of N -substituted lactamide-type homo and random acrylic copolymers under mild conditions. A particularly unique aspect of this work is that the water-soluble monomers and the SET-LRP initiator used to produce the corresponding polymers were synthesized from biorenewable and non-toxic solvents, namely natural ethyl lactate and BASF's Agnique® AMD 3L ( N , N -dimethyl lactamide, DML). The pre-disproportionation of Cu( i )Br in the presence of tris[2-(dimethylamino)ethyl]amine (Me 6 TREN) in water generated nascent Cu(0) and Cu( ii ) complexes that facilitated the fast polymerization of N -tetrahydrofurfuryl lactamide and N , N -dimethyl lactamide acrylate monomers (THFLA and DMLA, respectively) up to near-quantitative conversion with excellent control over molecular weight (5000 < M n < 83 000) and dispersity (1.05 < Đ < 1.16). Interestingly, poly(THFLA) showed a degree of polymerization and concentration dependent LCST behavior, which can be fine-tuned ( T cp = 12–62 °C) through random copolymerization with the more hydrophilic DMLA monomer. Finally, covalent cross-linking of these polymers resulted in a new family of thermo-responsive hydrogels with excellent biocompatibility and tunable swelling and LCST transition. These illustrate the versatility of these neoteric green polymers in the preparation of smart and biocompatible soft materials.

    Abstract Block copolymer brushes are of great interest due to their rich phase behavior and value‐added properties compared to homopolymer brushes. Traditional synthesis involves grafting‐to and grafting‐from methods. In this work, a recently developed “polymer‐single‐crystal‐assisted‐grafting‐to” method is applied for the preparation of block copolymer brushes on flat glass surfaces. Triblock copolymer poly(ethylene oxide)‐b‐poly(l‐lactide)‐b‐poly(3‐(triethoxysilyl)propyl methacrylate) (PEO‐b‐PLLA‐b‐PTESPMA) is synthesized with PLLA as the brush morphology‐directing component and PTESPMA as the anchoring block. PEO‐b‐PLLA block copolymer brushes are obtained by chemical grafting of the triblock copolymer single crystals onto a glass surface. The tethering point and overall brush pattern are determined by the single crystal morphology. The grafting density is calculated to be ≈0.36 nm−2from the atomic force microscopy results and is consistent with the theoretic calculation based on the PLLA crystalline lattice. This work provides a new strategy to synthesize well‐defined block copolymer brushes.

    Polymer nanoparticles are an emerging class of materials with potential impact in sensing, catalysis, imaging, cosmetics, and therapeutics. Here, a collection of graft polymers with conjugated polythiophene backbones were synthesized via a grafting-to approach. We functionalized polythiophene backbones with side chains of either poly(3-hexylthiophene) (P3HT), poly(ethylene oxide), or poly(methyl methacrylate) (PMMA) via copper-catalyzed azide–alkyne click chemistry. The backbones, graft polymers and a linear poly(3-hexylthiophene) were fabricated into nanoparticles through precipitation in aqueous media. We measured the absorption and emission spectra of the polymers dissolved in chloroform and as nanoparticles suspended in water. Compared to linear P3HT, all graft polymer nanoparticles exhibit higher quantum yields. Moreover, the addition of PMMA side chains increased the quantum yield by more than two orders of magnitude. This versatile approach to conjugated graft copolymer synthesis demonstrates a route for enhancing photoluminescence of conjugated polymer nanoparticles that could be beneficial for a variety of applications, such as biosensing and bioimaging.

    ABSTRACT Cellulose‐based polymer brushes with variable grafting densities and low dispersity were synthesized by grafting poly(n‐butyl acrylate) (PBA) side chains from cellulose‐derived backbones via ATRP. Esterification of commercially available cellulose acetate with 2‐bromoisobutyryl bromide (2‐BiBB) in NMP provided cellulose‐based macroinitiators averaging one initiation site per double glucose unit. ATRP macroinitiators averaging up to 6 initiation sites per repeating double glucose unit were prepared by acylation of microcrystalline cellulose (MCC) in LiCl/DMAc solvent system with 2‐BiBB. A series of linear macroinitiators with narrow MWD were obtained by fractional precipitation process. The content of initiating sites was determined by elemental analysis. (Meth)acrylate side chains were then grafted from the cellulose‐based macroinitiators. The prepared cellulose‐based polymer brushes showed tunable degradation rates dependent on grafting density of the brush, following two different degradation pathways, either cleavage of the main chain or detachment of the side chains. © 2019 Wiley Periodicals, Inc.

    Abstract Amphiphilic graft copolymers were prepared via a grafting through approach to yield materials with a hydrophilic backbone and hydrophobic arms. The thermally responsive macromonomers were designed to contain a Diels–Alder adduct such that cyclo‐reversion would cleave the arms from the backbone thus altering polymer topology, composition and solubility. The macromonomers were prepared via light‐inducted atom transfer radical polymerization followed by post‐polymerization modification to install a polymerizable functionality. Next, free radical polymerization was employed to yield thermally responsive amphiphilic graft copolymers, whose solution state characteristics were extensively characterized by UV/Vis spectroscopy and fluorimetry. Due to the amphiphilic nature of the graft copolymer, some unexpected results occurred because of aggregation and solubility limitations. Furthermore, it was discovered that poly(N‐isopropyl acrylamide) exhibited distinct and unique aggregation properties by itself.
