Influence of dodecyl surfactants on the cross-linking, plasticization and damping behavior of epoxy novolac resins

Autor: Sathiadasan Minu, Ramasubbu Ramani, Ramakrishna Indu Shekar, Teggina Math Kotresh, Naveen Vijay Padaki

Publikováno v: Soft Matter. 18:7380-7393

A series of modified epoxy novolac resins (ENRs) were prepared by incorporating dodecyl chain surfactants with polar groups such as amine, carboxylic acid, phenol, resorcinol and benzene sulfonic acid. Except for the case of benzene sulfonic acid, no

A comparative study on the influence of alkyl thiols on the structural transformations in P3HT/PCBM and P3OT/PCBM blends

Autor: Sarfaraz Alam, Ramasubbu Ramani

Publikováno v: Polymer. 54:6785-6792

Herein, we present a comparative study on the structural transformations in P3HT/PCBM and P3OT/PCBM blends using octane (C 8 ) and dodecane (C 12 ) thiols as solvent additives. Addition of dodecane thiol to the blends promotes needle-like PCBM crysta

Dielectric and conducting behavior of pyrene functionalized PANI/P(VDF-co-HFP) blend

Autor: Ramasubbu Ramani, Veer Singh, Vijay Pal, Amit Saraiya, Ajit Singh, P. K. Mishra

Publikováno v: Journal of Applied Polymer Science. 133

Herein, we present the dielectric and electrical conductivity properties of the partially miscible polymer blend prepared using pyrene functionalized polyaniline (pf-PANI) and poly(vinylidene fluoride-co-hexafluoro propylene) (PVDF-co-HFP). The blend

Evidence of PPII-like Helical Conformation and Glass Transition in a Self-Assembled Solid-State Polypeptide−Surfactant Complex: Poly(l-histidine)/Docylbenzenesulfonic Acid

Autor: Ramasubbu Ramani, Ari Laiho, Sirkku Hanski, Roman Tuma, Janne Ruokolainen, Olli Ikkala, Filip Tuomisto, Simo Kilpeläinen

Publikováno v: Biomacromolecules. 9:1390-1397

We present lamellar self-assembly of cationic poly(L-histidine) (PLH) stoichiometrically complexed with an anionic surfactant, dodecyl benzenesulfonic acid (DBSA), which allows a stabilized conformation reminiscent of polyproline type II (PPII) left-

Diffusion of seawater in unsaturated polyester resin and its glass fiber reinforced composites in the presence of titanium dioxide as UV absorber

Autor: Babu Lal, Ramasubbu Ramani, C. Ranganathaiah, Sarfaraz Alam, M.V. Deepa Urs

Publikováno v: Journal of Applied Polymer Science. 102:2784-2794

Diffusion of seawater in unsaturated poly- ester resin (UPR) and its glass fiber reinforced composite in the presence of titanium dioxide has been studied by sorption method. Incorporation of glass and TiO2 to UPR alters the seawater diffusion proces

Microstructure and properties of novel fluorescent pyrene functionalized PANI/P(VDF-HFP) blend

Autor: Sarfaraz Alam, Vijay Pal, Ramasubbu Ramani, Asit Prakash, Veer Pal Singh

Publikováno v: Journal of Applied Polymer Science. 131

We herein report the preparation and properties of the first polymer blend using pyrene functionalized polyaniline (pf-PANI). The pf-PANI has been synthesized and its blend has been prepared with the copolymer of vinylidene fluoride and hexafluoropro

Publikováno v: Physica Status Solidi C, 6(11), 2414-2416

We report here the first results of order-disorder transition (ODT) in a self-assembled comb-like polymer-amphiphile supramolecular system as identified from the change in positron lifetime parameters. We have used poly(4-vinyl pyridine) hydrogen bon
