The effect of sintering dispersed dispersion and nano-emulsion particles of high molecular weightpolytetrafluoroethylene(PTFE)on a substrate as a function of“melt”time and temperature is described.Folded chain singlecrystals parallel to the substrate and as ribbons on-edge(with double striations),as well as bands,are produced for longersintering times;particle merger and diffusion of individual molecules,crystallizing as folded chain,single(or few)molecule,single crystals when“trapped”on the substrate by cooling occur for shorter sintering times.It is suggested the observedstructures develop with sintering time,in a mesomorphic melt.The structure of the nascent particles is also discussed.
The effect of sintering dispersed dispersion and nano-emulsion particles of high molecular weight polyethylene polytetrafluoroethylene (PTFE) on a substrate as a function of “melt” time and temperature is described. Molded chain singlecrystals parallel to the substrate and as ribbons on-edge (with double strokes), as well as bands, are produced for longersintering times; particle merger and diffusion of individual molecules, crystallizing as folded chain, single (or few) molecules, single crystals when “trapped” on the substrate by cooling happen for lower sorties .It is suggested the observedstructures develop with sintering time, in a mesomorphic melt. The structure of the nascent particles is also discussed.
