“…It is then reasonable that these effects are comparable to the behaviour of a 'free surface' 5,38,39 that vanishes during annealing with the gradual anchoring of chains on the substrate and the consequent reduction of unoccupied sites at the interface. Our previous work on PS160 qualitatively supports this scenario 40 : the response of polymers annealed at lower temperatures mimic the trends of films with a layer of liquid-like thermal expansivity that does not vitrify when the system is cooled below bulk T g .…”

“…Films of glycerol, threitol and xylitol (degree of purity 499%, purchased from Aldrich), were prepared by organic molecular beam deposition directly on the IDE 30,39,40 , which made it possible to probe their dielectric response. The bulk material was heated above its melting temperature in a crucible connected, via a pneumatic valve, to a vacuum chamber maintained at a pressure pB10 -8 mbar.…”

“…The traditional fibre-reinforced plastics which are usually made up of glass, carbon or aramid fibres-reinforced thermoplastic and thermoset resins are considered critically and because of their environmental difficulties the manufacture, use and removal of traditional fibre-reinforced composites are less popular. Of late, there has been an increasing interest for alternatives which are the biodegradable plastic composites by using natural fibres [1][2][3][4]. The benefits of natural fibres are: biodegradability, renewability, low density, and low cost.…”

“…The promising applications of natural fibre reinforced composites: door, package trays, instrument panels, arm rest, seat back and glove boxes [1]. However, the natural and common drawbacks of natural fibres are the high degree of moisture absorption, poor wettability with non-polar polymers, low-adhesion of untreated fibres with polymer-matrix which facilitates the retardation of significant bonding during aging [3][4][5]. To overcome these drawbacks for increasing the applications of natural fibre reinforced composites, the possible recommendations are the fabriccation method of fibre, cautious choice of pair (fibre and matrix), and development procedures [6,7].…”
