Heat treatment of thin polymer films

Номер: US20120091628A1
Автор: Miroslav Planeta
Принадлежит: Macro Engineering and Technology Inc

Stretch film is treated by passing a web of tackifier-containing, unbloomed thin polymer film through a heater so that the web is heated to a temperature sufficient to cause tackifier bloom prior to the web reaching a next stage in an in-line process. Also, a pattern can be applied to a thin polymer film. An oriented web of thin polymer film is passed across at least one heated roller having the pattern engraved thereon to define face regions and relief regions collectively conforming to the pattern. As the web contacts each roller surface, portions of the web positioned over the relief regions receive less heat than portions of the web positioned over the face regions, thereby causing the respective portions of the web to undergo differential, heat-induced shrinkage which imparts the pattern to the thin polymer film.

A method and apparatus for removing a SMP apparatus from within a cured composite part. The method may comprise the steps of triggering the SMP apparatus from a rigid state to a malleable state, inducing a pressure differential that drives the SMP apparatus, in the malleable state, away from the cured composite part and toward an inner mandrel tool, and removing the inner mandrel tool with the SMP apparatus resting thereon out of the cured composite part. The inner mandrel tool may comprise an outer surface having varying contours such that a surface area of the outer surface is great enough to prevent the SMP apparatus from folding over onto itself or creasing when driven toward the inner mandrel tool. A maximum straight line distance between points on the outer surface may be small enough to allow the inner mandrel tool clearance for removal from the cured composite part.

A two-way shape-memory effect of the LCE may thereafter be programmed and locked into the LCE the second stage polymerization reaction. The self-limiting reaction allows for unprecedented control over LCE domain states and cross-linking densities, as well as the resultant mechanical and optical properties of the LCE formed. 1.

FABRICATION AND APPLICATION OF SHAPE MEMORY POLYMER POSSESSING TRANSESTERIFICATION INDUCED PERMANENT RESHAPING PROPERTY

Номер: US20170197356A1
Автор: WU JINGJUN, Xie Tao, Zhao Qian, ZOU WEIKE
Принадлежит: Zhejiang University

The present invention discloses the fabrication and application of a shape memory polymer possessing transesterification-induced permanent reshaping. The ester-containing crosslinked polymer is obtained by crosslinking ester bearing polymer precursors or by reaction of monomers which yield ester bonds. The transition temperature falls between 20-150° C. The reshaping temperature is tuned by catalyst amount and should be 20° C. above the transition temperature. The breakthrough of the present invention lies in integrating shape memory effect and plastic deformation into the same polymer and triggering the respective function at different occasions. The permanent shape of as synthesized polymer could be modified arbitrarily and cumulatively. Therefore, the hierarchical structure which could not otherwise be obtained due to the limit of mold fabrication process should expand the practical application of SMPs. 1. An application method of a shape memory polymer possessing transesterification-induced permanent reshaping property , the method comprising the steps of:a) (1) when the temperature reaches reshaping temperature, under the impact of an external force, the polymer with a certain original shape (shape I) is changed to an arbitrary desired new shape;b) (2) the temperature and external force remain stable to allow the transesterification reactions in the polymer system until dynamic equilibrium is reached;c) (3) the new shape is permanently fixed under cooling and now defined as the new original shape (shape II);d) (4) the processed polymer is further altered to a temporary shape (shape III) after being heated above the phase transformation temperature under an external force;e) (5) the temporary shape of step (4) shall be fixed after cooling below the phase transformation temperature;f) (6) the polymer obtained from step (5) is reheated to above its the phase transformation temperature so that the polymer will recover to the permanent shape (shape II) obtained in ...
