Journal ArticleDOI
Functional porous structures based on the pyrolysis of cured templates of block copolymer and phenolic resin
Harri Kosonen,Sami Valkama,A Nykanen,M Toivanen,G. ten Brinke,Janne Ruokolainen,Olli Ikkala,Antti Nykänen +7 more
TL;DR: In this article, a facile method to construct porous films by crosslinking phenolic resin in the presence of a self-assembled block-copolymer template, followed by pyrolysis at moderate temperature.
Journal ArticleDOI
Self-Organized Thermosets: Blends of Hexamethyltetramine Cured Novolac with Poly(2-vinylpyridine)-block-poly(isoprene)
TL;DR: In this article, a self-organization-based method was proposed to prepare thermally cross-linked nanostructured phenolic resins based on selforganization, where the block length of P2VP has been selected to be sufficiently high to allow the mutually hydrogen-bonded novolac and P 2VP, including HMTA, to be contained in the same microphase-separated domains.
Journal ArticleDOI
Hierarchical Porosity in Self-Assembled Polymers: Post-Modification of Block Copolymer-Phenolic Resin Complexes by Pyrolysis Allows the Control of Micro- and Mesoporosity
Sami Valkama,Antti Nykänen,Harri Kosonen,Ramasubbu Ramani,Filip Tuomisto,Peter Engelhardt,Gerrit ten Brinke,Olli Ikkala,Janne Ruokolainen +8 more
TL;DR: In this paper, self-assembled hierarchical porosity in organic polymers can be obtained in a facile manner based on pyrolyzed block-copolymer-phenolic resin nanocomposites and that a given starting composition can be post-modified in a wide range from monomodal mesoporous materials to hierarchical micro-mesoporous material with a high density of pores and large surface area per volume unit.
Journal ArticleDOI
Nanoscale Conducting Cylinders Based on Self-Organization of Hydrogen-Bonded Polyaniline Supramolecules
Harri Kosonen,Janne Ruokolainen,Matti Knaapila,Mika Torkkeli,K. Jokela,Ritva Serimaa,G. ten Brinke,Wim Bras,Andrew P. Monkman,Olli Ikkala +9 more
TL;DR: In this paper, a concept to achieve electrically conducting acid dopes was introduced to achieve a combination of rigid rod polymers and amphiphilic oligomers, which can be obtained by hydrogen bonding rigid rods and rigid rods.
Journal ArticleDOI
Self-organized cross-linked phenolic thermosets: thermal and dynamic mechanical properties of novolac/block copolymer blends
TL;DR: In this article, hydrogen bonding, dynamic mechanical properties and glass transition temperatures are investigated using Fourier transform infrared spectroscopy (FTIR) and dynamic mechanical spectrograms (DMA) using differential scanning calorimetry.
