Specialty processing techniques advancing electronic end-use development
By Don Rosato
End-use electronic application plastic process development is responding to the ongoing need for smaller electronic devices that in turn call for smaller, thinner electrical components. Convergence among computer, consumer electronics and telecom industries continue to blur the lines between information, entertainment and communication. Complex plastic components can now light up or heat up at a touch, opening new applications for plastic components with integrated electronics and functional surfaces.

SPE HIGHLIGHTS


Tough, biodegradable poly(L-lactic acid) polymer blends
SPE Plastics Research Online
Poly(L-lactic acid) PLLA is an aliphatic polyester that is used in textile fibers, paper coatings, and biomedicine. It has many advantageous properties: it is insoluble in water, completely biodegradable by composting, and is an optically active and transparent thermoplastic. However, slow crystallization rates under supercooling conditions permit large spherulites (spherical semi-crystalline regions) with cracks to form.1,2 In addition, the glass transition temperature of PLLA is 60°C, such that the polymer chain is immobile at room temperature. As a result, it is brittle and unsuitable for many applications, such as in food packaging.

    Caltech engineers focus on the nano to create strong, lightweight materials
    Plastics Engineering
    The lightweight skeletons of organisms such as sea sponges display a strength that far exceeds that of manmade products constructed from similar materials. Scientists have long suspected that the difference has to do with the hierarchical architecture of the biological materials — the way the silica-based skeletons are built up from different structural elements, some of which are measured on the scale of billionths of meters, or nanometers.

  • From dental braces to astronauts' seats
    The Economist
    Ever since 3-D printing hit public consciousness a couple of years ago, comment has veered towards two extremes. Fans, often in America, insist it will have a dramatic impact, undermining the economics of mass production and repatriating jobs to the West. ccording to the Harvard Business Review, "China will have to give up on being the mass-manufacturing powerhouse of the world." Critics denounce it as overblown hype — "a gimmick" according to Terry Gou, the boss of Foxconn, a manufacturing giant in China: he says he will start spelling his name backwards if he is proved wrong.

    PLA-thermoplastic lignin blends
    Plastics Engineering Magazine
    Lignin is the second most abundant natural polymer on earth after cellulose. It is one of the main constituents of plants and wood, giving them them their structural integrity and providing water transport. Currently a huge amount of lignin is generated as a byproduct of the paper and bioethanol industries. In the papermaking industry this lignin is directly used as fuel for boilers and thus provides energy for the process.

    As expected, Apple has launched a plastic iPhone, a "cheaper" addition to its smartphone range, although it remains to be seen if the market will consider it a bargain. The California company's design chief, Jony Ive, stressed the high-end manufacturing that goes into the one-piece polycarbonate outer body. "It is an extraordinarily rigid structure and has a solid, dense feel that you would not expect from a plastic product," he said.
