Microporous polyurethanes: Synthesis and investigation of the mechanism of the pore formation

Deepa, P; Jayakannan, M (Wiley, 2006)

A new approach for microporous polymeric material is developed utilizing the secondary interactions such as hydrogen bonding in the polymer chains in polyurethane systems at ambient conditions. A new series of highly rigid, ...
Multifunctional ZnO-Biopolymer nanocomposite coatings for health-care polymer foams and fabrics

Sanoop, P K; Mahesh, K V; Nampoothiri, K M; Mangalaraja, R V; Ananthakumar, S (Wiley, 2012)

Biopolymer-mediated sonochemical synthesis has been carried out for obtaining stable, nanocrystalline ZnO-biopolymer nanocomposite colloids to be applied on polymer foam and cotton fabrics to ultimately produce multifunctional, ...
Polyurethane-oligo(phenylenevinylene) random copolymers: pi-conjugated pores, vesicles, and nanospheres via solvent-induced self-organization

Deepa, P; Jayakannan, M (Wiley, 2008)

We report a new series of polyurethane-oligo(phenylenevinylene) (OPV) random copolymers and their self-assembled nanomaterials such as pores, vesicles, and luminescent spheres. The polymers were synthesized through melt ...
Solvent – induced self – organization approach for polymeric architectures of micropores, hexagons and spheres based on polyurethanes prepared via novel melt transurethane methodology

Deepa, P; Jayakannan, M (2007)

Solvent - induced self-organization approach was developed, for the first time, to produce polyurethane micro porous templates and higher ordered morphologies such as micro or nanometer- sized polymeric hexagons and spheres. ...
Solvent-Induced self-assembly in cardanol-based urethane methacrylate comb polymers

Rekha, N; Asha, S K (Wiley, 2009)

We report side chain urethane-methacrylate comb polymers based on the renewable resource cardanol and its saturated analogue 3-pentadecyl phenol and their self-assembly into pores, spheres, vesicles, tubes, and so forth. ...
Solvent-induced self-organization approach for polymeric architectures of micropores, hexagons and spheres based on polyurethanes prepared via novel melt transurethane methodology

Deepa, P; Jayakannan, M (Wiley, 2007)

Solvent-induced self-organization approach was developed, for the first time, to produce polyurethane microporous templates and higher ordered morphologies such as micro or nanometer-sized polymeric hexagons and spheres. ...
Synthesis and characterization of rubber-seed-oil-based polyurethanes

Bakare, I O; Pavithran, C; Okieimen, F E; Pillai, C K S (Wiley, 2008)

Novel biobased polyurethanes were synthesized from rubber seed oil (RSO), a renewable resource. The RSO monoglyceride, together with xylene and hexamethylene diisocyanate (HMDI), was employed to synthesize the desired ...
