摘要： METHOD IN WHICH A GAS IS DISSOLVED WITHIN A MOLTEN THERMOPLASTIC POLYMER DURING ITS PASSAGE THROUGH AN EXTRUDER TO PROVIDE A SUPER-SATURATED SOLUTION OF DISSOLVED GAS THEREIN AS SUCH POLYMER APPROACHES AND ENTERS A REGION OF LOWER PRESSURE OUTWARDLY OF THE EXTRUDER. AT A LOCATION NEAR THE BEGINNING OF THE ZONE OF THE SUPERSATURATED SOLUTION OF DISSOLVED GAS, THE THERMOPLASTIC POLY-

MER IS SUBJECTED TO SONIC VIBRATIONS TO CAUSE INCIPIENT BUBBLE FORMATION THEREIN. SUCH BUBBLES ARE PERMITTED TO EXPAND IN THE REGION OF LOWER PRESSURE, AFTER WHICH THE THERMOPLASTIC POLYMER IS QUENCHED.

摘要： Composite foams having cells containing shape-stabilized phase change material (ss-PCM) particles are described. Composite foams may be made by contacting a plurality of ss-PCM particles and one or more pre-polymer reactants, wherein each ss-PCM particle can form a nucleation site for foam cell generation. The composite foams may be used in regulating the temperature of an article wherein the foam undergoes a phase transition as the surrounding temperature of the article approaches the foam's phase transition temperature. The thermostatic material may exchange heat with the article during the phase transition, resulting in regulation of the temperature of the article. The composite foams may be used as a thermostatic packaging material having a cavity for storing goods.
摘要翻译：描述了具有包含形状稳定相变材料（ss-PCM）颗粒的单元的复合泡沫。可以通过使多个ss-PCM颗粒和一种或多种预聚物反应物接触来制备复合泡沫，其中每个ss-PCM颗粒可以形成泡沫细胞产生的成核位点。复合泡沫可以用于调节制品的温度，其中随着制品的周围温度接近泡沫的相转变温度，泡沫经历相变。恒温材料可以在相变期间与制品交换热量，从而调节制品的温度。复合泡沫体可以用作具有用于储存物品的空腔的恒温包装材料。

摘要： A selective high intensity ultrasonic foaming technique is described to fabricate porous polymers for biomedical applications. Process variables, including ultrasound power, scanning speed, and gas concentration have an affect on pore size. Pore size can be controlled with the scanning speed of the ultrasound insonation and interconnected porous structures could be obtained using a partially saturated polymers. A gas concentration range of 3-5% by weight creates interconnected open-celled porous structures. The selective high intensity ultrasonic foaming method can be used on biocompatible polymers so as not to introduce any organic solvents. The method has use in cell related biomedical applications such as studying cell growth behaviors by providing a porous environment with varying topological features.

摘要： A method for producing rigid sugar micro-/nanofoams includes providing a solution with at least one sugar, a super- or near-critical fluid and a surfactant component as a (micro)emulsion. The (micro)emulsion is expanded so as to convert the super- or near-critical fluid from a state of liquid-like density to a state of gaseous density so as to thereby obtain a micro-/nanofoam. The micro-/nanofoam is then rigidified so as to obtain a rigid sugar micro-/nanofoam.
