    • Improved fabricated adhesive microstructures and methods of fabricating adhesive microstructures incorporating deformable materials are provided. We have found that the fabricated adhesive microstructures exhibit significantly improved adhesion strengths at least at smooth surfaces such as glass, as compared to known fabricated adhesive microstructures. Advantageously, we have found that the adhesion strengths of fabricated microstructures of the invention for a range of smooth glass contact surfaces may be in the range of between about 125kPa and 220kPa in air at one atmosphere pressure and in the range of between about 25kPa and 12OkPa in vacuum. Conveniently, synthetic elastomers are used in the invention. A method (55) (steps 1. to 5.) of fabricating new adhesive microstructures (75) having multiple levels of compliance with a surface has been proposed. Methods of fabricating new double-sided adhesive microstructures via moulding have further been proposed.
    • 提供了改进的制造的粘合剂微结构和制备包含可变形材料的粘合剂微结构的方法。 我们已经发现,与已知的制备的粘合剂微结构相比,所制造的粘合剂微结构至少在诸如玻璃的光滑表面显示出显着改善的粘合强度。 有利地,我们已经发现,在一个大气压力的空气中,对于一系列平滑玻璃接触表面的本发明的制造的微结构的粘合强度可以在约125kPa至220kPa之间的范围内,并且在约25kPa至120kPa 在真空中。 方便地,在本发明中使用合成弹性体。 已经提出了制造具有多个与表面的柔顺程度的新的粘合剂微结构(75)的方法(55)(步骤1.至5.)。 进一步提出通过模塑制造新的双面粘合剂微结构的方法。
