Buildings may be capable of repairing themselves in the future. It sounds like science fiction, but scientists are developing self-repairing polymer materials whereby cracks can be sealed automatically.<br />The technology being developed has been inspired by the human body's ability to repair minor cuts without any external intervention.<br />There are two such technologies in polymer materials: adhesives and thermal encapsulation.<br /><br />The first involves a series of 'stores' of adhesive distributed homogenously throughout the material,so that when the crack reaches one of these nodes, the adhesive is secreted, together with a catalyst,and the crack is closed and the material polymerised.<br /><br />There are two variants within this technology, depending on whether adhesive-containing microcapsules or tubes filled with adhesive are employed.<br /><br />INASMET-Tecnalia, a private technological centre in Spain, has worked on this line. It has managed to produce a series of microcapsules and distribute them in a polymeric resin.This was a fundamental step to finding out the difficulties that might arise in the encapsulation process.<br /><br />The second method, developed by Bristol University, is a project for the European Space Agency (ESA), is very similar. The difference lies in the use of tubes rather than microcapsules filled with adhesive.<br /><br />The thermal method uses a different repair technology. The material, developed by the University of Sheffield, is a polymeric matrix compound, reinforced with carbon fibres. <br />The polymer matrix, in turn, is made of a solid solution of a thermoplastic polymer and another thermostable polymer.<br /><br />The development of self-repairing materials is still at initial stages and there is a long way to go before reaching the desired goal. Nevertheless, the results are encouraging.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8380481751214832942-3112249881589930996?l=watermlics.blogspot.com' alt='' /></div>WATERMLICShttp://www.blogger.com/profile/05403556195940707401noreply@blogger.com0tag:blogger.com,1999:blog-8380481751214832942.post-68495596538361714572008-03-06T08:41:00.001-08:002008-03-06T08:42:31.651-08:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://bp3.blogger.com/_uX7U-M5zWz4/R9Ae1FAFZiI/AAAAAAAAAFo/nu_KLTX-vDM/s1600-h/Services+of+watermlics_1.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://bp3.blogger.com/_uX7U-M5zWz4/R9Ae1FAFZiI/AAAAAAAAAFo/nu_KLTX-vDM/s320/Services+of+watermlics_1.jpg" alt="" id="BLOGGER_PHOTO_ID_5174669869073131042" border="0" /></a><br /><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/6UJnfjMJQwo"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/6UJnfjMJQwo" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8380481751214832942-6849559653836171457?l=watermlics.blogspot.com' alt='' /></div>WATERMLICShttp://www.blogger.com/profile/05403556195940707401noreply@blogger.com0tag:blogger.com,1999:blog-8380481751214832942.post-4450018589750153192008-03-06T08:39:00.000-08:002008-03-06T08:40:16.478-08:00<object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/VgeK2j8PWhA"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/VgeK2j8PWhA" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8380481751214832942-445001858975015319?l=watermlics.blogspot.com' alt='' /></div>WATERMLICShttp://www.blogger.com/profile/05403556195940707401noreply@blogger.com0tag:blogger.com,1999:blog-8380481751214832942.post-46641416512362890382008-03-06T08:37:00.000-08:002008-03-06T08:39:13.908-08:00<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://bp3.blogger.com/_uX7U-M5zWz4/R9Ad_FAFZhI/AAAAAAAAAFg/ac7_YUG16bs/s1600-h/Visiting+card+watermlics_6.jpg"><img style="margin: 0pt 10px 10px 0pt; float: left; cursor: pointer;" src="http://bp3.blogger.com/_uX7U-M5zWz4/R9Ad_FAFZhI/AAAAAAAAAFg/ac7_YUG16bs/s320/Visiting+card+watermlics_6.jpg" alt="" id="BLOGGER_PHOTO_ID_5174668941360195090" border="0" /></a><br /><br /><br /><br /><br /><br /><br /><object height="355" width="425"><param name="movie" value="http://www.youtube.com/v/VgeK2j8PWhA"><param name="wmode" value="transparent"><embed src="http://www.youtube.com/v/VgeK2j8PWhA" type="application/x-shockwave-flash" wmode="transparent" height="355" width="425"></embed></object><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/8380481751214832942-4664141651236289038?l=watermlics.blogspot.com' alt='' /></div>WATERMLICShttp://www.blogger.com/profile/05403556195940707401noreply@blogger.com1
